Don't blame our ancestors for making you fat, we wouldn't live to lose weight without this trick. We humans are the most cooperative species. Modern parents have to take care of children picked up from trash cans, which is because most of us humans focus on sports and rarely fight alone. In addition, humans also cooperate to hunt food and make tools, which can only be done with language. Of course, our ability to hunt large animals is also thanks to our throwing arms, which are now used to play baseball when we don't need to hunt, and our thumbs that allow us to make ingenious tools and crafts.
We and the common ancestor of telemarketing list chimpanzees separated for four or five million years at least. During this time, many human races coexisted on the earth, but in the end, only we, Homo sapiens, not only survived, but also ruled the whole world. We used to think that Homo sapiens wiped out other species of Homo, including Neanderthals, and their genetic material was not even left. But thanks to the efforts of Svante Pääbo , author of Neanderthal Man: In Search of Lost Genomes , and others in ancient DNA research, we found that It turns out that there were erotic flows between Homo sapiens and Neanderthals before ancient times.
People outside of Africa have 1 to 4% of their genomes from Neanderthals, and the genetic test I did also showed that I had 215 genetic variants from Neanderthals, which doesn't count More, because 94% of their customers have more customers than me in their database. If we go back to our ancestors, not to mention that we are related to the great apes, and we have all the creatures on the earth. If you are interested in our all the way back to our common ancestor with all living things in the world, you can refer to Richard.
