Yes, which is not at all in contradiction with the fact that speciation is a vertical process of species evolving into 1 or more sub-species.
Birds, reptiles, mammals,... = all vertebrates, for example.
Yes, and all of them still belong to the same ancestral groups that they branched off from.
Insects didn't branch of from mammals. Dear, your knowledge on evolution is extremely lacking.

Mammals and insects share ancestry as shown by the DNA, which can be visualized in phylogenetic trees. Family trees.
Here is a highly resolved and automatically generated tree of life, based on completely sequenced genomes:

It doesn't. Creation doesn't predict any nested hierarchies. Evolution does.
Evolution explains why you don't find mammals with feathers, creation doesn't.
Evolution explains why we share thousands of ERV's with chimps, but not as much with cats, but still more with cats then with frogs. Creation doesn't.
Evolution explains our fused chromosome and why, when split, it matches chromosome 13 of chimps. Creation doesn't.
Creation doesn't explain
anything. It merely asserts based on nothing other then religious beliefs. It's entire raison d'être comes from religion.
Demonstrably false.
"Precisely"?
