Evidence of Evolution Review

Some organisms that share a common ancestor have features that have different functions, but similar structures.  These are known as

• vestigial structures
• analogous structures
• homologous structures
• fossil structures

Embryos of chickens, fish and humans look very similar. They all have folds known as gill slits

in the neck region. What may this suggest?

• they all formed in the ocean

• they all evolved from a common ancestor

• they are all going extinct

Notice the similarities of a shark and dolphin. If these similarities developed by living in similiar environments and not by common ancestry. Which of the following vocabulary words would best describe them?

• a. Vestigial Organ

• b. Embryological Similarities

• c. Homologous Structures

• d. Analogous Structures

The solidified remain or imprint of a once living thing are called:

• Fossils

• Homologous Structures

• Vestigial Structures

• DNA

Adaptations are:

• physical or behavioral tendencies.

• physical or behavioral characteristics that help an organisms survive and reproduce.

• physical or behavioral characteristics that do not help the organism in any way.

• genetic mutations that have gone wrong.

The similarities of the bones in the diagram provide evidence that---

• The organisms shown lived in the same natural envionrment
• The organisms shown may have developed from a common ancestor
• The organisms shown have the same genetic diseases
• All vertebrate species have identical forelimbs
