Evolution/Organisms Unit Review

What is suggested by the similarity of early embryos of different species of vertebrates?

• no evolutionary relationships between the groups
• recent common ancestry
• similar environments in the past
• evolution from a distant common ancestor

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

Tags

NGSS.MS-LS4-2

Two organisms that are closely related would have

• very similar DNA sequence
• exactly the same DNA sequences
• no proteins in common
• completely different DNA sequence

What effect of genetic drift would occur after the small population has left the first island and then first island is hit by a storm?

• Founders effect

• Bottleneck Effect

• Structural adaption

• Geographical Isolation

NGSS.MS-LS2-4

Body parts that have similar structures but different functions; suggests that organisms share a common ancestry are referred to as?

• vestigial structures

• homologous structures

• adaptive radiation

• fossil

How do fossils provide evidence that evolution has happened on Earth?

• Fossils show how the sizes of certain animals has changed drastically over millions of years
• Fossils show that some species have gone extinct
• Fossils show how life forms present today are different than those from the past
• Different sedimentary rock layers provide evidence for how the environment has changed over time

Protein sequences in one organism that resemble those of another suggest a
