Like all good scientific theories, evolution must have scientific

evidence to support it

Like all good scientific theories, evolution must have scientific

evidence to support it

This evidence falls into 8 or more important categories:

1. Fossil Record2. Homologous structures3. Analogous structures4. Vestigial structures5. Geographical distribution6. Embryological studies7. Genetic & biochemical comparisons8. Resistance to antibiotics & pesticides

B. What evidence did scientists use to determine the fossil they found was that of a whale?

C. How do scientists use fossils to learn when whale ancestors were living on earth?

Watch the 10 minute video (Video # 3: “How Do We Know Evolution Happens”) answer the Questions above in your notebook:

A. Color-code the homologous structural parts on the sheet "Adaptive Radiation: Mammalian Forelimbs."

B. What are homologous structures? C. Why are these considered evidence for

Adaptive Radiation or Divergent Evolution?

A. What are vestigial structures? Give an example of a vestigial structure in humans. Give an example of a vestigial structure in some

other organism.

A. What is embryology? Compare the stages of development illustrated on the sheet

"Comparative Embryology" and in the diagrams in the Glencoe textbook (Page 433, Figure 18.11)

Create a branching diagram (like a family tree) which shows the degree of relationship between the animals listedin these pictures (Pg. 433, fig. 18.11) (6 total). Relationships are based on the similarity of their embryos.
