Nowadays, scientists have a lot of evidence in terms of people’s evolution, and it’s available in different forms. Human fossils enable them to study specific changes that happened in human body sizes and brains, dieting, and other important aspects, especially when researching early species. There are endless paintings, stone tools, footprints, and other traces in prehistorical records that can tell us more about early humans and their innovations.
The main purpose of human genetic is to show people how closely they are related to other primates and living organisms. This is what indicates the prehistoric migration of species all over the world. Besides, the latest advanced in the dates of artifacts and fossils help people define the exact age of these remains and paint a clearer picture of human evolution and its solid proofs.
The universal genetic code is a very important aspect because all cells, including simple bacteria and tree leaves, can read the DNA from other living forms. This evidence is quite strong and it indicates on a common ancestor from which all the other life forms descended. Fossil records shouldn’t be overlooked because they show that their simplest forms can be found in the oldest rocks. They also indicate a gradual and smooth transition from one life form to others.
Different genetic commonalities are important too because people have about a big part of their genes in common with such animals as cats, chimpanzees, cows, mice, and so on. Well, this fact can’t prove that human beings evolved from cats or other animals, but it proves that we all shared the same ancestor in the past. Moreover, differences in our genomes correspond to how long ago specific genetic lines were diverged.
Think about common traits in embryos because monkeys, snakes, humans, eels, and others are called chordates as they belong to the same phylum. One of their basic characteristics is that their embryos have tails, gill slits, and other anatomical structures, so all chordate embryos are quite similar to each other. Finally, bacterial resistance to antibiotics shouldn’t be overlooked when studying this subject. Bacteria colonies can build up their resistance to all antibiotics only via the process of evolution, and there are some people who have this resistance too because of their random mutations, so this fact also proves evolution concepts.
