Textbook Question
Chapter 40, Problem 1TYK
Tunas, dolphins, penguins, and sharks all have a fusiform body shape. What is the best explanation for this similarity?

- b. The physical laws of hydrodynamics drove the natural selection for this shape.
- c. All aquatic animals have this shape, an example of convergent evolution.
- d. This shape is determined by the
thermodynamics of maintaining body temperature in cold water.

Despite not sharing a recent common reptilian ancestor, both mammals and birds are homeotherms. Which of the following statements best explains how this trait came about?
A.
The development of homeothermic capabilities is the result of convergent evolution due to similar selection pressures
B.
Similar development of homeothermic capabilities is the result of adaptive radiation from a reptilian ancestor
C.
Birds and mammals diverged from dinosaurs, which were homeothermic
D.
Mammals and birds both inherited homeothermic capabilities from an ancient reptilian ancestor and then diverged
E.
Similar homeothermic capabilities in birds and mammals can be explained through homologous structures

A.
Evolutionary mismatch is not a real concept.
B.

Fruits and vegetables were disadvantageous for early humans to eat, but they are healthy for modern humans.
