Discussion:
Hominin Diversity, Invertebrate Diversity, Evolutionary History, and Origins of Species
Question 1
In which we explore hominin diversity.
A. Explain the evidence that suggests hominins did not evolve in a straight line leading directly to our species.
Question 2
In which we explore invertebrate diversity.
A. Explain how a hydrostatic skeleton helps an animal keep its shape and move.
Question 3
In which we discuss tracing evolutionary history.
A. Describe how radiometric dating and the relative position of a fossil within a rock strata are used to determine the age of rocks and thus the age of the fossil.
Question 4
In which we discuss tracing the origins of species.
A. Describe the circumstances that led to the adaptive radiation of the Galapogos finches.
