I have a question about how the animal kingdom is spread out over the world. For example, you have bears in almost all the continents, felines, primates, fish in the lakes, or even snakes are to be found all over the world. But how come early hominids are seemingly only found around the northern africa/europe area? I apologize if any of this is incorrect. I just was thinking about it and was surprised that hominids haven't branched out in a more diverse way around the earth. It seems like other animals diversified and spread out but humans are concentrated in a smaller area. Hope the question makes sense, thanks!
PS completely unrelated... how do I use the quote function so that when I reply to someone I don't have to have their entire reply quoted, thanks
Many mammals, such as bears and cats, have been around for a much longer period of time than humans. Early humans were the new kids on the block and so their fossil remains are found in a relatively limited area. But you see this same pattern with the early fossils of many new species. They had to evolve somewhere.
Exactly right. We have evidence of ancestors to bears going back 33+ million years. Early hominid 6-7 million.
