The evolution of animal species has been prolific (current estimates of species numbers reach into the tens of millions). Much of this diversity is a result of the evolution of novel ways to ________.
A) reproduce
B) arrange cells into tissues
C) sense, feed, and move
D) form an embryo and establish a basic body plan

Question

Sensing, feeding, and movement are all key aspects of an animal's survival and have contributed significantly to the diversification of animal species. Reproduction and formation of a basic body plan are also important factors in evolution, but do not account for as much of the diversity seen in the animal kingdom as sensing, feeding, and movement. Cell arrangement into tissues is an important step in the development of complex organisms but is not as directly related to animal diversity as the other options.
