Evolution

Question 1

Evolution

Answer 1

The slow, gradual change in species over time

Question 2

Structural Evidence (SE)
Fossil Evidence
Embryonic Evidence
Homologous Structures
Analogous Structures
Vestigial Structures

Question 3

Fossil Evidence

Answer 3

Fossils are remains of a once living organism that have been preserved through natural process

Question 4

Embryonic Evidence

Answer 4

Embryos from distantly related species show remarkable similarities

Question 5

Homologous Structure

Answer 5

Structures that share an appearance internally, but externally perform different functions

Question 6

Analogous Structures

Answer 6

Structures that preform the same function, however species achieve that function differently.

Question 7

Vestigial Structures

Answer 7

Remnants of a once working organ or tissue. Often they are much smaller then they once were, and provide no useful function

Question 8

Molecular Evidence (ME)
Amino Acids Sequencing
DNA Sequencing
GEL Electrophoresis

Question 9

Amino Acid Sequencing

Answer 9

Scientists compare the amino acids sequences of proteins to help determine evolutionary relationships among species

Question 10

DNA Sequencing

Answer 10

More recently, the DNA sequences between species can be analyzed and compared to determine evolutionary relationships

Question 11

GEL Electrophoresis

Answer 11

DNA can also be analyzed and compared among species using gel electrophories to produce a DNA fingerprint. The banding patterns can then be compared to determine evolutionary relationships
