So what's the point? If each gene (or protein) gives you a different phylogenetic tree, then how exactly does it shows us the relationship between the species? How does it prove evolution?

Thanks, but still, I expect that if you'll take several represent animals (monkeys, humans, dogs, cats, zebras, horses, birds, bats, squirrels, fish, whales, dolphins ...) and you'll build several phylogenetic trees for them based on several different genes and proteins, then you should get very similar trees. If not, then you can't say that phylogenetic trees are evidence of evolution. So my question is still relevant, how close are the different trees to one another?

Hi all, I read that phylogenetic trees are one of the strongest evidence of evolution, because we get a very similar trees for different genes and proteins. But I can’t find anywhere ANY concrete/specific numbers. How many phylogenetic trees where constructed so far? 1000? 50,000? a million? How similar are they to one another? 99%? 95%? 80%? I would really like to see some numbers, where can I find them? I’m asking this because I came across a video claiming that phylogenetic trees do NOT support evolution: https://www.youtube.com/watch?v=lk1gDk1wGhQ&t=5m52s So, if you have some numbers it will really help. Thanks.
