How similar are phylogenetic trees?

Stop and think.If you were making a tree of mammals would bears on the same branch together with cats and dogs and Giraffes and tigers?Now if you were making a tree of carnivorous mammals, which of those items would be left out?Now if you were making a tree of herbivore mammals, which of those items would be left out?

Why you examine the evidence used to create the tree as well as the reason it was created.It really is that simple.It is all truly simple and ALL of the evidence has led to the inescapable conclusion that life on the earth evolved over billions of years.Any other position is at best simply uninformed but more often simply a con job.

I offer a few examples for you and hope you can use them.Look at a tree that has cow, dog, seal, giraffe, lion, bat, bird.Now that would be a valid tree of currently living species.Look at a tree that has cow, dog, seal, giraffe, lion, bat. That would be a valid tree of mammals but the bird would lack features that allow it to be called a mammal.Phylogenetic trees are not just random associations. They are based on the actual physical evidence that is found in each item in the list.Even critters as different as a bat, a seal, a lion and a giraffe share common features that allow them to be classified under the broad tree called mammals.

All of those were addressed in the part of my post you omitted.
