Question

1. what is a primary contribution of biogeography to the understanding of evolution?

a. comparative anatomy analysis
b. detailed dna sequences
c. fossilized remains
d. distribution patterns of species

1. non - random mating occurs when individuals choose mates based on:

a. genetic diversity
b. random preferences
c. environmental conditions
d. specific traits

1. which of the following structures is an example of homologous structures?

a. the flippers of a dolphin and the arms of a human
b. the eyes of an octopus and the eyes of a human
c. the fins of a fish and the wings of a bat
d. the wings of a butterfly and the wings of a bird

Explanation:

• For question 7: Biogeography studies the distribution of species. It helps in understanding evolution by showing how species are spread across different regions and how this distribution relates to evolutionary history.
• For question 8: Non - random mating occurs when individuals select mates based on specific traits like physical appearance or behavioral characteristics.
• For question 9: Homologous structures have a similar underlying structure due to common ancestry. The flippers of a dolphin and the arms of a human have similar bone structures despite different functions, indicating a common evolutionary origin.

Answer:

1. d. Distribution patterns of species
2. d. Specific traits
3. a. The flippers of a dolphin and the arms of a human
