Evidence for Evolution

Common ancestry relates to evolution because

• evolution only happens when there are common ancestors.
• Common ancestors make evolution happen more quickly.
• evolution can never take place with common ancestors.
• the more two organisms have in common, the more recent is their common ancestor during their evolution.

The appendix, tailbone, and wisdom teeth are all examples of what type of structure in humans?

• Homologous

• Analogous

• Vestigial

• Modern

In stage one (top row) of these embryos, most of the embryos________

• look very similar.
• have very different features.
• show different stages of development.
• have only a tail if they are non-human.

A type of structure that is physically present, but does not seem to serve a significant function for an organism.

• Homologous structure

• Analogous structure

• Vestigial structure

• Standard structure

What type of evidence is represented in the picture above:

• Fossils

• Vestigial Structures

• DNA

• Homologous Structures

Body parts similar in structure and origin

• evolution

• embryology

• homologous

• variation

The fossil record help scientists

• better understand the kinds of organisms that lived in the past

• better understand how the environment has changed over time

• better understand how organisms have evolved over time

• all of the above

According to this data, the unknown bacterial species is most closely related to: 

• Species I
• Species II
• Species III
• Species IV

What type of evidence is shown in the image above?

• Fossils

• Vestigial structures

• Homologous Structures

• DNA

How does embryology support the Theory of Evolution?

• It shows that they have a common ancestor because of their similarities.
•          I'm not sure.
• Animals change over time.
