Thanks for your answers, 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?
