After a lake dried up during a severe drought, a section of undisturbed rock layers was exposed. The layers are represented below.


This sequence of rock layers best illustrates the concept that:

Title: Turtle Cells and Human Skin

New research has demonstrated that turtles and humans may have had a common
ancestor 310 million years ago. A recent study looked at the genes responsible for the skin
layers of turtle shells compared to the genes for human skin. The findings of the study
suggest that about 250 million years ago, when turtle evolution split from other reptiles, a
mutation in a specifi c group of genes occurred. The basic organization of this group of genes
is similar in turtles and humans, and they produce the important skin proteins that produce
shells in turtles and protect against infection in the skin of humans.
Base your answer to question 20 on the information to the left and on your knowledge of biology.
