STAAR - Day 4

The scientific theory of evolution is supported by different types of evidence. The diagrams below show the skeletons of two different animal species. How does comparing the skeletons of these animals provide support for the scientific theory of evolution?

•  It provides information about the organisms' habitats.
•  It shows possible common ancestry between organisms.
• It provides information to determine the organisms' ages.
•  It shows possible chromosomal similarities between organisms.

A small portion of the population that is geographically isolated from the rest of the population runs the risk of decreased.

• genetic drift
• mutation rate
• natural selection
• genetic variation

Theodosius Dobzhansky discovered that successful species tend to have a wide variety of genes that do not appear to be useful to the species in its present environment. What did this discovery help explain about genetics and the changes that occur in a species over time?

• Environments with more organisms tend to have more successful species.
• Species with greater genetic diversity adapt more easily to changing environments.
• Changing environments prevent species from adapting and surviving.
• Species in a stable environment are more resistant to a changing environment.
