The Indian Ocean is between Asia, Africa, Oceania and Antarctica. It is the third largest ocean in the world, with a total area of 74.917 million square kilometers, about 1/5 of the total ocean area. Its average depth is 3897 meters and the deepest is 7729 meters. The northern part of the Ind
The Atlantic Ocean is between Europe, Africa, America and Antarctica. It is the second largest ocean in the world and the youngest ocean, only 100 million years ago. The Atlantic Ocean has an area of 93.363 million square kilometers, an average depth of 3627 meters, and a maximum depth of 921
The Pacific Ocean is between Asia, Oceania, Antarctica and the Americas. It is the largest of the world's oceans. It is about 19,000 kilometers wide from east to west and about 16,000 kilometers long from north to south. It covers an area of 180 million square kilometers, accounting for 35% o
On the earth we live on, there are continents and oceans. And the ocean is much larger than the land. According to calculations by scientists,the Earth’s surface area is 510 million square kilometers, of which the ocean occupies 70.8%, or 361 million square kilometers. The remaining 149 mill

Scientists recently believed that the ugly herbivorous reptile called "bunostegos" was discovered to have evolved from 260 million years ago, and its fossils have now proven that this creature appeared earlier than the dinosaurs. "Bunostegos" are cow-like in appearance, with bulbous growths o
It’s not just humans who are jealous, it’s not just humans who have love rivals, it’s not just humans who have wars with love rivals, it’s the same in the animal kingdom. Whether they are humans or animals, the desire for control and possessiveness between lovers is the same. When you see
1. Dinosaurs also wooed by wagging their tails. Scientists came to this conclusion after studying small flightless dinosaurs, modern birds and reptiles. Oviraptorosaurs had strong, soft tails with colorful feathers that they could show off. "Such a tail is perfect for showing off t
Different eras require animals to have different survival abilities. If you lived in ancient times, huge size and ferocious habits once became the most important characteristics of animals. Currently, 593 species of birds, more than 400 species of animals, 209 species of amphibians and reptil
The end of the Cretaceous period witnessed one of the most dramatic mass extinctions in Earth's history. Find out what caused the extinction of dinosaurs and many other animals. The fossil record shows that during the first 175 million years of their existence, dinosaurs took on a variety of
Although dinosaurs lived millions of years ago, we know they existed because some of them became fossils after they died. How were dinosaur fossils formed? Below we explore this process in more detail. Skull fossil of the dinosaur Hypsilophodon, found in the UK
Dinosaurs were a group of reptiles that dominated land for more than 140 million years (more than 160 million years in some parts of the world). They evolved in different shapes and sizes, from the terrifying giant Spinosaurus to the chicken-sized Microraptor, and were able to survive in a va
作为能人的后代，在距今大约２００万年前的非洲，直立人出现在人类进化的历史舞台上。直立人直立人的脑子已经明显增大，早期成员的脑量就已经达到８００毫升左右，晚期成员则上升为１２００毫升左右。而且，脑子不仅仅是体积增大了，它的结构也变得更加复杂并进行了重新改组，显示出直立人已经有了相当复杂的文
Our current human beings are members of the genus Homo. They evolved from Homo habilis through Homo erectus and early Homo sapiens. Why did only early members of the genus Homo develop into modern humans while the various Australopithecus species living at that time failed to continue develop
Among the relics of the Peking people discovered in Zhoukoudian, there are not only a large number of stone tools, but also many tools made of animal bones or horns - bone tools. A more important discovery is the evidence that people in Beijing used fire. Among the eviden
The origin of the hominid family represented by Ardipithecus and Australopithecus was an evolutionary leap, marking the differentiation of the human family from other groups of higher primates. The next leap was a leap within the human family: a group closer to us in the family Hominidae, the
We already know that the oldest groups of members of the family Hominidae known so far are basically found in the east of the African continent. But the story doesn't end there. Early human footprints In 1976, a research team led by Mary Leakey discov
