• Fossil Record

• Prokaryotic Cells

• Eukaryotic Cells

• Adaptation

A more complex cell type that does have membrane bound organelles, such as a nucleus

• Fossil Record

• Prokaryotic Cells

• Eukaryotic Cells

• Adaptation

A change or the process of change by which an organism or species becomes better suited to its environment

• Fossil Record

• Evolutionary Relationship

• Natural Selection

• Adaptation

A detectable change in the internal or external environment for an organism that causes a response in that organism

• Adaptation

• Natural Selection

• Fossil Record

• Stimuli

Times in Earth's history where many organisms became extinct at one time

• Periodic Extinction

• Natural Selection

• Fossil Record

• Stimuli

This is made of all the fossils discovered on Earth

• Fossil Record

• Prokaryotic Cells

• Eukaryotic Cells

• Adaptation

These are similar physical features in an organism that do share a common ancestor but the features serve different functions

• Homologous Structure

• Analogous Structure

• Vestigial Structure

• Cladogram

Features of different species that are similar in function but did not come from a common ancestor; structures that evolved in response to a similar environmental challenge

• Homologous Structure

• Analogous Structure

• Vestigial Structure

• Cladogram

A diagram that shows the relationships between species of an organism

• Fossil Record

• Evolutionary Relationship

• Natural Selection

• Cladogram

A structure on an organism that has no apparent function and appears to be "left over" parts from a past ancestor

• Homologous Structure

• Analogous Structure

• Vestigial Structure
