Answer 3

A species refers to a group of organisms that look alike and can interbreed to produce fertile offspring

What are the 3 types of species concepts you can use to identify species?

Answer 4

Morphological Species Concept
Biological Species Concept
Phylogenic Species Concept

Question 5

Give a brief description on the Phylogenic Species Concept

Answer 5

examines the phylogeny, or evolutionary history of an organism

Question 6

Answer 6

whether two organism can produce fertile offspring

Question 7

focuses on morphology
- body shape, size, and other structural features

Question 8
