Why are giraffes so tall?

Reading and enjoying these following facts about why are giraffes and baby giraffe get so long neck

Around 15 million years ago, antelope-like animals were roaming the dry grasslands of Africa. There was nothing very special about them, but some of their necks were a bit long.

Within a mere 6 million years, they had evolved into animals that looked like modern giraffes, though the modern species only turned up around 1 million years ago. The tallest living land animal, a giraffe stands between 4.5 and 5 metres tall – and almost half that height is neck.

Most people assume that giraffes’ long necks evolved to help them feed. If you have a long neck, runs the argument, you can eat leaves on tall trees that your rivals can’t reach. But there is another possibility. The prodigious necks may have little to do with food, and everything to do with sex.

The evidence supporting the high-feeding theory is surprisingly weak. Giraffes in South Africa do spend a lot of time browsing for food high up in trees, but elsewhere in Africa they don’t seem to bother, even when food is scarce.
Girls like them long

Giraffes’ necks are long, but there have been longer ones. Sauropod dinosaurs trump them easily: the dinosaur Mamenchisaurus, for instance, had a neck over 9 metres long, four times the longest of giraffe necks.

Long necks come at a cost. Because a giraffe’s brain is around 2 metres above its heart, the heart has to be big and powerful. In fact, for the blood to reach the brain it has to be pumped at the highest pressure of any animal. So there must be a big payback to keep giraffes’ necks so long.

The latest theory – and it’s a surprise this hasn’t come up before, given biologists’ fixation with it – is that the long necks are the result of sexual selection: that is, they evolved in males as a way of competing for females.

Kết quả hình ảnh cho Why are giraffes so tall?

Male giraffes fight for females by “necking”. They stand side by side and swing the backs of their heads into each others’ ribs and legs. To help with this, their skulls are unusually thick and they have horn-like growths called ossicones on the tops of their heads. Their heads, in short, are battering rams, and are quite capable of breaking their opponents’ bones.

Having a long and powerful neck would be an advantage in these duels, and it’s been found that males with long necks tend to win, and also that females prefer them.

The “necks for sex” idea also helps explain why giraffes have extended their necks so much more than their legs. If giraffes evolved to reach higher branches, we might expect their legs to have lengthened as fast as their necks, but they haven’t.

Neck and neck

The problem for the sex idea is that it implies that female giraffes shouldn’t have long necks, and they plainly do. Sexual selection often drives males to develop spectacular attributes – think peacocks’ tails or the feathers of birds of paradise – to impress females, but the females remain relatively dowdy.

A study last year by Graham Mitchell of the University of Pretoria in South Africa and colleagues apparently delivered a knock-down blow to the “necks for sex” theory. Mitchell’s team showed that, in Zimbabwe at least, males and females had necks that were almost exactly the same length, and that if anything the females’ necks were longer. This led many people to write off the whole sex idea.

However, Rob Simmons and Res Altwegg of the University of Cape Town, also in South Africa, have taken a second look at Mitchell’s results and are not convinced. They say the figures do show that males have proportionally longer necks, and that “Mitchell et al. appear to have misinterpreted this result”.

Kết quả hình ảnh cho Why are giraffes so tall?

They point to a study in Namibia which found that males consistently had heavier necks than females with the same body mass, and that only the males’ necks kept growing throughout their lives. Males’ heads were also heavier than females’, which is what you would expect if they were being selected for their ability to fight.

Simmons and Altwegg suggest that giraffes’ necks may have begun growing as a way of eating hard-to-reach food, but that they were then “hijacked” for mating purposes. Once the necks had reached a certain length, males could use them for necking and clubbing – and at that point sexual selection took over, driving the necks to their current extreme lengths.

Peacocks and birds of paradise aside, there are many birds of which the male seems to have developed colourful plumage as a result of sexual selection, but the females are also brightly coloured. Perhaps the sexual selection explanation for long necks in giraffes isn’t dead after all.

Vitamin C helps reduce anxiety among diabetics

It's the fact that vitamin c helps reduce anxiety among diabetics. Let's see how

Kết quả hình ảnh cho vitamin c helps reduce stress

But this effect upon moods has also been found among diabetics, as another study found that the antioxidant vitamin C can significantly reduce stress and anxiety among type 2 diabetic patients.

The research divided 45 diabetes mellitus patients into three groups. For six weeks, they gave one group 1,000 milligrams per day of vitamin C, and another 400 IU per day of vitamin E. They gave the third group a placebo. The researchers used a 21-question test called the Depression Anxiety Stress Scale before and after the treatment period.

After the six weeks, those patients taking the vitamin C experienced a significant reduction in anxiety levels. The other two groups experienced no difference in anxiety.

Yes, patients with diabetes mellitus often suffer from anxiety, depression and stress. This was theorized as diabetes producing greater oxidative stress within the cells and tissues, which impacts brain cells and the production of mood neurotransmitters.

Tigers can climb trees

Don't you know why and when do tigers climb trees? Just keep reading to know more about this tigers facts

Although able to climb trees, tigers rarely climb trees; they can easily reach 500 pounds, which is far too heavy for efficient climbing. Tiger cubs have been seen going up and down trees for fun, but they do so less as they grow larger. 
Mostly, tigers avoid climbing trees because they don't always know how to get down, which leads to very awkward situations.

Cubs:

Kết quả hình ảnh cho does tiger climb tree

Tiger cubs willingly climb trees for about the first sixteen months of life and young tigers have been sighted following langur monkeys up into the trees in an effort to secure a feed. But after this age their increasing weight makes both ascent and descent difficult, and few tree branches have the needed strength to hold their weight.
Also see elephant facts

Adults:

Adults seldom climb, but are quite capable of doing so; they may do this if being chased by dogs or when after prey. There have been occasions of men climbing trees to escape an attacking tiger, only to be killed when the tiger followed them up. 
This does not mean tigers are willing or efficient climbers. On the contrary, they are not. The white Bengal and Amur tigers shown here are doing something quite unusual for tigers of their age.

Dragons have been discovered in our times

Whether or not dragons exist, they have been discovered in our times. Keep reading for more amazing animal facts about dragons:


This species has many features similar to the legendary dragons we’ve heard about. It is capable of gliding flight, it is carnivorous being a reptile and it lays eggs. The recorded maximum length of this species is around 23 cm, now that’s a bit low for dragons right?

Well perhaps there are some secrets still left to be discovered, like may be it was evolution or even magic that got all dragons to shrink !


No this species doesn’t breath fire either but then again it might be choosing not to ? or perhaps the decrease in size has rendered it incapable of fire, probably due to decreased intelligence. The possibilities are endless.

Animal question: Can cockroaches fly?

Can you answer animal facts question: Can cockroaches fly?



To answer your question simply, yes.

The very thought of cockroaches can send shivers down your spine. These pesky creatures are synonymous with dirt and filth, and are also known to spread diseases such as salmonella, whilst also triggering asthma.

There are around 4,500 species of cockroaches in the world, but only 30 are considered pests. But can these crawling insects fly?

Some basic infor about penguins

Enjoying these following penguin facts about their living place, diet and mating and baby penguins

Where do penguins live?


Considered marine birds, penguins live up to 80 percent of their lives in the ocean, according to the New England Aquarium. All penguins live in the Southern Hemisphere, though it is a common myth that they all live in Antarctica. In fact, penguins can be found on every continent in the Southern Hemisphere. It is also a myth that penguins can only live in cold climates. The Galapagos penguin, for example, lives on tropical islands at the equator.

What do penguins eat?

A penguins diet consists primarily of fish, squid and krill.

Depending on the species of penguin their food preference can vary which also helps reduce competition for food.

Large colonies are able to consume millions of pounds of food on a daily basis.

Penguins rely on their eyes to find food while underwater.

Most dives for food do not exceed 60 feet, although some species are capable of diving nearly 2,000 feet for when hunting for prey.

They capture their prey by grabbing it with their bill and swallow their food whole.

Penguins are known to fast (stop eating) annually during breeding periods when they must watch their eggs, keep them warm and prevent them from being attacked by predators.

Before fasting they stock up by consuming large quantities of food so that they can build up enough energy from fat to last them throughout their fasting period.

Mating and baby penguins


A group of penguins is called a colony, according to the U.S. Geological Survey. During breeding season, penguins come ashore to form huge colonies called rookeries, according to Sea World.

Most penguins are monogamous. This means that male and female pairs will mate exclusively with each other for the duration of mating season. In many cases, the male and female will continue to mate with each other for most of their lives. For example, research has found that chinstrap penguins re-paired with the same partner 82 percent of the time and gentoo penguins re-paired 90 percent of the time.

At around three to eight years old, a penguin is mature enough to mate. Most species breed during the spring and summer. The male usually starts the mating ritual and will pick out a nice nesting site before he approaches a female.

After mating, the female emperor or king penguin will lay a single egg. All other species of penguins lay two eggs. The two parents will take turns holding the eggs between their legs for warmth in a nest. The one exception is theemperor penguin. The female of this species will place the egg on the male's feet to keep warm in his fat folds while she goes out and hunts for several weeks.

When penguin chicks are ready to hatch, they use their beaks to break through the shell of their eggs. This process can take up to three days. After the chicks emerge, the parents will take turns feeding their offspring with regurgitated food. Penguin parents can identify their offspring by unique calls that the chick will make.

Tiger - Where do they live?

Reading and enjoying these following tiger facts -  facts of one of the most amazing big cats in the world.

Tigers are found in amazingly diverse habitats: rainforests, grasslands, savannas and even mangrove swamps. Unfortunately, 93 percent of historical tiger lands have disappeared primarily because of expanding human activity. Saving tigers means saving forests that are vital to the health of the planet. You can help by taking action to save tiger forests.


In many areas, the number of tigers is dwindling due to poaching and loss of habitat, and the reproduction rate of tigers is not high. A female typically produces two to three cubs every 2 to 2 1/2 years, because cubs are not fully independent until they are about 2 years old. About one-half of all cubs do not survive long enough to go out on their own. Females are ready to reproduce at 3 to 4 years old, but males do not first mate until they are 4 or 5.

How importance of science is?

Everyone know the science facts that science is important because it influences most aspects of everyday life but how? 

Science is important because it influences most aspects of everyday life, including food, energy, medicine, transportation, leisure activities and more. Science improves human life at every level, from individual comfort to global issues.


When they hear the term “science”, a lot of people usually imagine some guy wearing a lab coat and safety glasses, operating some high-tech machinery or mixing some funny-looking substances; in fact, science can be a lot simpler than that. Science is actually not something that’s strictly happening into a laboratory, but rather everything that follows a certain pattern, and can be replicated if some conditions are met. Throwing a rock up, just to see it fall down to the ground can be considered science, as the rock will always fall down, thus demonstrating that gravity is present, and that it works.

The bigger misconception is that you have to understand how it all works in order to take advantage of it – this couldn’t be more false. Just think about it this way: you may not know much about electricity or electronics, but you know that if your TV is plugged into the power socket, once you push the power button on the remote, it will turn on. How do you know that? It’s simple – because you’ve done it over and over again, with the same results. But science gave us much more than non-stop television.

  2. Food is often swallowed whole – bits of fur and bone are then regurgitated (coughed up) as an owl pellet.
  3. Barn Owls screech – they never hoot (that’s Tawny Owls).
  4. The scientific Latin name for Barn Owl is Tyto alba alba.
  5. Barn Owls have very long legs, toes and talons to help them to catch prey hidden under long grass.
  6. Most owls hunt insects, small mammals and other birds.
  7. Some owl species hunt fish.
  8. Owls have powerful talons (claws) which help them catch and kill prey.
  9. Owls have large eyes and a flat face.
  10. Owls can turn their heads as much as 270 degrees.
  11. Owls are farsighted, meaning they can’t see things close to their eyes clearly.
  12. Owls are very quiet in flight compared to other birds of prey.
  13. The color of owl’s feathers helps them blend into their environment (camouflage).
  14. Barn owls can be recognized by their heart shaped face.
  15. Barn Owls usually hunt at night – even in total darkness they can find the smallest vole using their super-sensitive hearing.
  16. Barn Owls’ large eyes are very sensitive too – they can quickly spot a mouse moving in a very gloomy barn.
  17. Barn Owl feathers are super soft – this helps them to hunt silently, but they are not very waterproof and get soaked if it rains.
  18. Barn Owls have lop-sided ears! One is higher than the other, which helps them to pinpoint exactly where tiny sounds are coming from.
  19. A wild Barn Owl usually eats about 4 small mammals every night, that’s 1,460 per year!

What are the pig facts?

Reading and enjoying these following animal facts about pigs

pigs are smart

  • Pigs snuggle close to one another and prefer to sleep nose to nose. They dream, much as humans do. In their natural surroundings, pigs spend hours playing, sunbathing, and exploring. People who run animal sanctuaries for farmed animals often report that pigs, like humans, enjoy listening to music, playing with soccer balls, and getting massages.
  • Pigs communicate constantly with one another; more than 20 vocalizations have been identified that pigs use in different situations, from wooing mates to saying, “I’m hungry!”
  • Newborn piglets learn to run to their mothers’ voices and to recognize their own names. Mother pigs sing to their young while nursing.
  • According to Professor Donald Broom of the Cambridge University Veterinary School, “[Pigs] have the cognitive ability to be quite sophisticated. Even more so than dogs and certainly [more so than human] 3-year-olds.”
  • Think that pigs are slow and lumbering? As it turns out, they’re not at all! Adult pigs can run at speeds of up to 11mph, or in other words, they can run a seven-minute mile. Could you do any better?
  • Pigs appear to have a good sense of direction and have found their way home over great distances. Adult pigs can run at speeds of up to 11 miles an hour.




pigs-exploring

  • Like humans, pigs are omnivores, meaning they eat both plants and other animals.
  • A pig’s snout is an important tool for finding food in the ground and sensing the world around them.
  • Pigs have an excellent sense of smell.
  • There are around 2 billion pigs in the world.
  • Humans farm pigs for meat such as pork, bacon and ham.
  • Pigs do not “eat like pigs” or “pig out.” They prefer to eat slowly and savor their food.
  • Suzanne Held, who studies the cognitive abilities of farmed animals at the University of Bristol’s Centre of Behavioural Biology, says that pigs are “really good at remembering where food is located, because in their natural environment food is patchily distributed and it pays to revisit profitable food patches.”
  • Pigs are clean animals. If given sufficient space, they will be careful not to soil the area where they sleep or eat. Pigs don’t “sweat like pigs”; they are actually unable to sweat. They like to bathe in water or mud to keep cool, and they actually prefer water to mud. One woman developed a shower for her pigs, and they learned to turn it on and off by themselves.

Kết quả hình ảnh cho tiger facts for kids

  1. The tiger is capable of killing animals over twice its size; it is one of nature’s most feared predators.
  2. Like its ancestor, the sabre-tooth cat, the tiger relies heavily on its powerful teeth for survival. If it loses its canines (tearing teeth) through injury or old age, it can no longer kill and is likely to starve to death.
  3. Tigers live alone and aggressively scent-mark large territories (up to 100sq km in size) to keep their rivals away.
  4. They are powerful nocturnal hunters that travel many miles to find buffalo, deer, wild pigs, and other large mammals. A Bengal tiger can eat 21kg of meat in a night and can kill the equivalent of 30 buffaloes a year.
  5. The roar of a Bengal tiger can carry for over 2km at night.
  6. Although tigers are powerful and fast over short distances, the Bengal tiger cannot outrun fleet footed prey such as deer. Instead it uses stealth to catch its victims; attacking from the side or the rear.
  7. Tigers use their distinctive coats as camouflage (no two have exactly the same stripes).
  8. If the kill is large, the tiger may drag the remains to a thicket and loosely bury it with leaves, then return to it later.
  9. As well as game animals, it preys on wild boar, monkeys, lizards and occasionally porcupines.
  10. Females give birth to litters of two to six cubs, which they raise with little or no help from the male. Cubs cannot hunt until they are 18 months old and remain with their mothers for two to three years, when they disperse to find their own territory.
  11. Like domestic cats, all tigers can purr. Unlike their tame relatives, however, which can purr as they breathe both in and out, tigers purr only as they breathe out.
  12. Unlike other cats, tigers are good swimmers and often cool off in lakes and streams during the heat of the day.
