How much similarity can be seen between the current body plans of organisms and the body plans seen in fossils from the Cambrian Period?

There is considerable similarity in the body plans of ancient animals and today’s
animals. The basic body plan of the elephant was evident in the tiny pikaia, a
small swimming animal. The body plan of this animal was passed on to fish,
amphibians, reptiles, birds and mammals.

Can someone put the answer in there own words!
