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.

What are fossils?

• Are the remains or evidence of once-living organisms

• Is the change over time in populations of related organisms

• A chart that divides Earth’s history into different time units

• Occurs when the last individual organism of a species dies

What is biological evolution?

• Is made up of all the fossils ever discovered on Earth

• Is the preserved evidence of the activity of an organism

• Are the remains or evidence of once-living organisms

• Is the change over time in populations of related organisms

Study of embryos of various organisms to show a common ancestor because of similarities in development

• natural selection
• embryology
• speciation
• evolution
