That s where similar environmental factors lead to traits that are unrelated similar in species. Think rheas (South america) ostriches (Africa) and emus (Australia.

All are unrelated large flightless birds that evolved on different continents. I m not sure what drives trees to grow taller

Antarctica's Baby Penguins A December 2012 expedition from Princess Elisabeth station marked the first time humans saw this colony of flightless birds.

Large flightless birds such as the Diatryma thrived. Â The Neogene Period gives rise to early primates including early humans.

Cheetahs prey on warthogs gazelles antelopes rabbits porcupines and even ostriches and they catch their prey by chasing it down.

The 9 Weirdest Animal Penises The most primitive group of birds paleognaths which include emus kiwis

and ostriches have developed well phalluses as well. Along the evolutionary line two newer groups diverged: anseriformes which include penis-wielding ducks swans and geese and galliformes

Dozens of species disappeared altogether including 17 giant lemurs three pygmy hippopotamuses two aardvarklike mammals a giant fossa (a catlike carnivore) eight elephant birds a giant crocodile and two giant tortoises.

There were also some flightless birds such as ostriches rheas and moas. The flightless birds did not fare as well as they had to compete with mammals

and other creatures for limited supplies of food and water as a good portion of the water was frozen.

The large flightless birds went extinct in the mid-19th century. Other species disappeared before scientists had a chance to study their remarkable biological abilities like the gastric brooding frog which vanished from Australia in the mid-1980s likely due to timber harvesting and the chytrid fungus.

Flightless birds such as ostriches and emus don't have big tail-feather fans and birds that do have big tail-feather fans such as peacocks

or megafauna such as marsupial versions of lions rhino-size wombats giant kangaroos and flightless birds but about 90 percent of that megafauna disappeared during this time.

#Ostrich Facts: The World's Largest Bird Ostriches are large flightless birds that have long legs

and a long neck that protrudes from a round body. Males have bold black-and-white coloring that they use to attract females.

Ostriches are bigger than any other bird in the world. They can grow up to 9 feet (2. 7 meters) tall

145 kilograms) according to the African Wildlife Foundation and an ostrich's eyes are 2 inches (5 centimeters) in diameter the largest of any land animal.

The ostrich is the only bird that has two toes on each foot. All other birds have three or four toes according to the American Ostrich Association.

Wild ostriches live in the dry hot savannas and woodlands of Africa. They once roamed all over Asia Africa

and the Arabian peninsula but because they have been hunted so extensively wild ostriches'range has been reduced to Sub-saharan africa according to the University of Michigan Museum of Zoology.

However ostriches can be found in captivity all over the world. Ostriches are omnivores which means they eat both vegetation

and meat Although they prefer plants especially roots seeds and leaves they also eat locusts lizards snakes and rodents according to the San diego Zoo.

They also eat sand and pebbles to help grind up their food inside their gizzard

Ostriches don't need to drink water; they get all the water they need from the plants they eat.

Male ostriches are called cocks or roosters and females are called hens. A group of ostriches is called a flock.

Flocks can consist of up to 100 birds though most have 10 members according to the San diego Zoo.

Their feathers will turn a silvery color according to the American Ostrich Association. Ostrich eggs are 6 inches (15 cm) in diameter

and can weigh up to 3 lbs. 1. 3 kg. Eggs are laid in a communal nest called a dump nest

Ostrich offspring are larger than any other bird baby. At birth chicks can be as big as chickens.

An ostrich can live 50 to 75 years. Ostriches are in the same order as cassowaries emus kiwis and rheas.

The taxonomy of ostriches according to the Integrated Taxonomy Information system (ITIS) is: According to the International Union for Conservation of Nature's (IUCN) Red List most ostrich subspecies are endangered not though their populations are declining.

The Somali ostrich is listed as vulnerable though their population is unknown. It is believed that they are on a rapid decline.

It may seem amazing that an ostrich's thin legs can keep their large bodies upright.

Their legs are placed perfectly so that the body's center of gravity balances on top of its legs. Their thin legs give them great speed and maneuverability too.

They can run up to 40 mph (64.3 km h) for sustained periods of time according to the American Ostrich Association.

Contrary to popular belief ostriches don't bury their heads in the sand but they do lie down with their heads against the ground

when they feel threatened. It only looks like the ostrich has buried its head because its head

and neck blend in with the color of the sand. Ostriches fight with their feet. They kick forward because that's the direction in

which their legs bend according to the American Ostrich Association. A solid kick can kill a lion.

Ostrich feathers look shaggy because they hang loosely and don't hook together like feathers on other types of birds y

#Chimps Are Naturally Violent, Study Suggests For years anthropologists have watched wild chimpanzees go ape and attack each other in coordinated assaults.

I've also had an opportunity to work with rhea (flightless birds native to South america) that we raised

I heard one of the rheas running towards me. I turned to look and saw a male completely fluffed up

I soon made my way to the door leaving the hissing puffed-up kicking rhea behind.

To study how male birds lose their penises the UF researchers examined the embryonic development of birds with penises (ducks and emus) and birds without penises (chicks) among other creatures.

In other birds like ducks and emus that gene stays switched off allowing their penises to grow fully.

and dispersed by today's larger-bodied animals such as emus or elephants. If these plants are adapted for dispersal by a set of animals that has been missing from Earth's fauna for tens of thousands of years then how can they still be around today?

Australian cycads once coexisted with megafauna that could have dispersed their large heavy seeds--such as giant ground birds bigger then present day emus

Since their potential Australian prehistoric megafaunal dispersers became extinct around 45000 years ago why haven't Australian cycads begun to evolve smaller seeds that would be dispersed more readily by flying birds or possums for example over the interim?

Of course, there are native animals that are edible too (such as kangaroos, crocodiles and emus), but Weatherhead prefers to educate us on the wonders of Australias native flora world.
