Question

Almost all of the major animal body plans seen today appeared in the fossil record at the beginning of what period?

Answer 1

Answer:

The Cambrian Period of the Paleozoic Era.

Explanation:

In the Cambrian Period there was an "explosion" of different types of living things. Most of the major phylums of invertebrates suddenly appear in the fossil record. There are no transitional fossils for these phylums found in the Precambrian rocks.

Richard Dawkins says " The Cambrian strata are the oldest in which we find most of the major invertebrate groups. And we find many of them already in an advanced state of evolution the very first time they appear. It is as though they were planted there without any evolutionary history Needless to say this appearance of sudden planting has delighted creationists. # The blind watchmaker p 229
