16
Q

Grouping organisms together based on their evolutionary history is called?

A

Evolutionary classification

17
Q

What are the ways to see how closely related two organisms are?

A

DNA and RNA, homologous structures, embryological similarities and fossil records

18
Q

What are DNA complementary pairs?

A

(A-T) (C-G)

19
Q

What is a homologous structure

A

Are similar physical features in organisms that share a common ancestor

20
Q

What are embryological similarities?

A

They are similarities you can see in vertebrae embryos before hatching and they show similarities which can support common ancestry

21
Q

What are fossil records and how do they work?

A

By arranging the fossil records of a group of organisms in a chronological sequence, scientists can decipher how they evolved

22
Q

What is the dichotomous key?

A

A dichotomous key is a tool used to sort and identify unfamiliar organisms

23
Q

What is taxonomy?

A

Is the branch of biology that identifies and classifies organisms
