Evidence for evolution

Question 1

Fossils
(EFE)

Answer 1

The preserved remains of plants and animals buried in sediments
-provides a record of how creatures evolved

Question 2

Biogeography
(EFE)

Answer 2

study where organisms live now and where their ancestors lived in the past
-the distribution of species on different continents

Question 3

Homology structures

Answer 3

structures that have similar physical features in organisms that share a common ancestor, but the features serve a completely different purpose.
-provide evidence for common ancestry,

Question 4

Analogous structures

Answer 4

structures that serve similar functions but don’t share the same structures and development EX:fins of fish
-similar selective pressures can produce similar adaptations

Question 5

Vestigial structures

Answer 5

structures inherited from ancestors but have lost their original size and functions EX:whales have vestigial pelvic bones
-show how ancestors lived and how it evolved

Question 6

Comparative embryology
(EFE)

Answer 6

the study of the similarities in the embryos of different species
-Similarities in embryos

Question 7

homology

Answer 7

refers to similarity of a structure , physiology, or development of different species based upon a common ancestor.

Question 8

survival of the fittest

Answer 8

organisms that adapt to their environment and effectively pass on genes

Question 9

adaptation

Answer 9

A trait that helps a living thing survive and reproduce in its environment

Question 10

Common ancestor
(EFE)

Answer 10

A relative from the past that two or more different species share
-share similar DNA structures

Question 11

DNA
(EFE)

Answer 11

DNA sequence comparisons can show how different species are related.
