I doubt that any evidence, experiment, or research could prove that humans evolved from Neanderthals. Neanderthals and humans both evolved from Heidelberg Men (Homo heidelbergensis). Genetic evidence, cloning, and geometric reconstruction can effectively establish that humans (Homo sapiens) and Neanderthals (Homo neanderthalensis) evolved from Homo heidelbergensis, but it is difficult to irrevocably prove something like that, as it cannot be, as far as we know, recreated in a laboratory.
Multi-cellularity evolved from mutations. This is how everything evolved throughout history. Random mutations that prove to be advantageous, and allow a species to continue to reproduce.
If someone steals it and swapps it
There is only partial hypothesis to prove that Humans really evolved from the early Hominids. Despite evolutionary evidences in fossils and other genetic similarities in DNA , the species Homo Sapien is a distinct class and in no way related to other species.
Dinosaurs evolved before chickens .
They never died out. Modern Europeans are descended from the Cro-Magnon.
Yes.
Science does not " prove " things! The experiment gave us some evidence that it was possible under certain conditions and with the addition of energy that many biomolecules could be formed from common gasses.
The prospective voter had to prove he could read and write.
Humans die, therefore not perfect. You may find my answer misplaced, but it is not as yours, unless you define what you mean by perfection
The single fact that montag could not prove was that Clarisse has been there but he had no evidence. Montag saw a fire through the trees.
Humans did not evolve from chimpanzees. According the the theory of evolution, all types of organisms share a common ancestor. Those "basic" species evolved into other species. So humans and chimpanzees are descended from a common primate ancestor Humans decended from a common ancestor, one of which evolved to the chimps and the other to humans. So we are therefore the 5th ape. All living things share a universal common ancestor as we are the products of evolution by natural selection. And there are skeletal remains to prove it.
yes
