evolution

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.

• The organisms belong to the same genus.
• The organisms are native to the same geographic areas.
• The organisms will grow into anatomically similar adults.
