The earliest animal group to evolve was probably the?

Question

annelids, sponges, chordates or mollusks?

Answer 1

Sponges.

Answer 2

"Evolution" is a controversial topic, but some "evolutionary" claims are not controversial at all. There is overwhelming evidence of evolutionary changes within species. Examples are the development of insecticide resistance by insects, and, famously, coloring changes in the English Peppered Moth. Even the most ardent young-earth creationists do not dispute that this sort of "microevolution" takes place. However, the evidence of entirely new species developing from different species is a bit more tenuous. The best evidence for it is found, not in the fossil record, but in genetics. In particular, the evidence for "lower" (simpler) species evolving into "higher" (more complex) species is disputed. The weakest of all of the evolutionist claims is for abiogenesis: the assertion that living creatures somehow sprang from abiotic origins through undirected evolution. No plausible, coherent explanation for how that could have happened has been suggested. Note that the term "species" is rather malleable. Classically, a species is defined as a group of creatures which closely resemble each other and can produce fertile progeny when interbred. However, there is a tendency, these days, to call any distinguishable variety a species, in part for political reasons. For example, the Florida Panther is virtually indistinguishable from the Texas Cougar except for a kink near the tip of the tail, and the two varieties of cat interbreed freely, yet the Florida Panther is a legally protected "endangered species," even though its Texas cousin is not endangered. (If the same standard were applied to domestic animals, there would be dozens of dog species!) This is not the sort of "species" distinction that I meant when I referred to an "entirely new species" in the third paragraph, above. In answer to your question, the assertion that "humans evolved from monkeys" is questionable. However, I don't think that anyone would dispute that Florida Panthers and Texas Cougars evolved from common ancestors. Whether they really should be called different species, however, is debatable.

Answer 3

According to most authorities, is the sponges (Phylum Porifera).

Answer 4

do you believe in theory of evolution? becouse if human evolved from monkeies, why are there monkeies now. any way the answer is probrobly sponges
