About Changing lineages
6 Across answers meet 4 Down answers. Compare population-level mechanisms, inherited variation and shared ancestry. Reproductive contribution is different from physical strength, and structures with a shared history need not have the same present function. These terms differ from the animal features in Survival strategies.
