Trees fork, yes. But not all branches arise from the same spot on the trunk.
Everything so far fits on a tree.
This trend can be expected to continue.
Trees have branches.
Animals with mammary glands came from reptiles.
Other animals without mammary glands came from reptiles.
Do evos think dinosaurs gave rise to anything? Where do the dinosaurs fit in?
Continuing in the evolutionist's mode, I suppose the model states that there was yet an earlier branching, again one which may be unsupported in the fossil record, at which point the dinos, suddenly and conveniently equipped with the necessary dino genes, forked away from something earlier, and so on, working back all the way to the un-Godly ooze from which the theory claims we all arose. So in the evolution model, it's "fork, fork, fork, all the way down." Rather like turtles, no?
Oh, I read your question too hastily in making my prior answer. You are asking if the dinos have descendants today. I don't know. Clearly there are many extinct species. Some could be dead-ends. I don't have an answer for you.
What a proof of evolution! So tell us, what kind of tree is this? A pear tree, a mimosa, an oak tree? We are dying to know. Is it the same tree Noah built his ark from? It seems to have enough branches to fit all creation in it!
