Day+54+Evidence+for+Evolution+and+Speciation

Daily Agenda: 1. Vocab Quiz 6b - 20 minutes 2. Notes: Evidence for Evolution and Speciation - 20 minutes 3. Amino Acid / Speciation Lab - 30 minutes 4. Evolution Review Sheet - 10 minutes

Objective: 3.05 Examine the development of the theory of evolution by natural selection including: • Development of the theory. • The origin and history of life. • Fossil and biochemical evidence. • Mechanisms of evolution. • Applications (pesticide and antibiotic resistance).

Amino Acid Lab: The table below shows the amino acids found in a portion of the protein, hemoglobin, of different vertebrates. Hemoglobin is present in red blood cells to carry oxygen throughout the body. [|Amino Acid Lab Table.pdf]

1. Count the number of molecules of each amino acid in human hemoglobin and record in Data Table 1 of your lab sheet.

2. Count the number of molecules of each amino acid in the hemoglobin of other vertebrates. Record your numbers in Data Table 1 of your lab sheet.

3. Going from left to right, note the position of each amino acid. Count the number of similarities in the amino acid position in the human hemoglobin as compared with the hemoglobins of each of the other vertebrates. Record your numbers in Data Table 2 of your lab sheet.
