Activity 8: Studying Hominids
Introduction
Read the introduction.
A lineage is a series of populations of a
single species or several species
descended from a common ancestor.
Activity 8: Studying Hominids
Challenge

about Evolution”
Add information from this activity or a
previous activity to support whether any
of the statements are correct or
incorrect.
Activity 8: Studying Hominids
Analysis 1
Suppose you analyzed the DNA sequences for a
number of DNA segments in humans, chimpanzees, and
gorillas and you collected the data in the table below.
Explain how these data are related to the amino acid
data from Part B and how they explain the evolutionary
relationship between humans, chimps, and gorillas.
