How long have humans been on Earth? And how old are other Earths inhabitants? What were the first animals on our planet? If we traveled back millions of years in a time machine, we'd find some species looking much as they do today. For example, mosquitos looked pretty much the same as most of the 3, 500 mosquito species that exist nowadays. The first cats ancestor appeared 10 to 15 million years ago. The first specimen recognizable as bats appeared already 52 million years ago!
As for humans, Homo sapiens appeared around 300, 000 years ago in Africa. But they were smaller than their ancestors and had impressively big brains, less heavy jaws, and smaller teeth. Let's find out what are the oldest creatures on Earth (new discoveries make scientists believe that some forms of life on Earth could have evolved more than a billion years ago) Date: 2022-04-19
