FOCUS ON ORGANIZATION

Early tetrapods had a sprawling gait, like that of a lizard: As the right front foot moved forward, the body twisted to the left and the left rib cage and lung were compressed; the reverse occurred with the next step. Normal breathing, in which both lungs expand equally with each breath, was hindered during walking and prevented during running. In a short essay (100-150 words), explain how the origin of dinosaurs, whose gait allowed them to move without compressing their lungs, could have led to emergent properties in biological communities.

fossil bird salamander 2. This fossil bird and this living salamander both have tails. However, they have different tail structures. The bird has a very short tail made of just one bone that helps it have a light skeleton for flying. The salamander has a long tail with many bones that helps it balance while it runs. What most likely explains why both the bird and salamander have tails and why the tails are different? a) The salamander and bird both inherited tails from a shared ancestor population, but this population separated into different environments. In each environment, different types of tails evolved, which helped the populations survive. It is impossible to explain the body structures of different species. The way that structures change over time is very complex, and no one has ever observed these changes occurring. The bird and salamander are different species, so they do not share an ancestor population. These species had separate ancestor populations, and each evolved a…

Recall that amphibians gave rise to the earliest reptiles who then branched off to all the different kinds of reptiles and mammals. List two major adaptations present in REPTILES* that allowed them to live completely on dry land, as compared to amphibians.
