Flashcards in Species Concepts and Taxonomy Classification Deck (12):
1

Biological Concept

Populations of organisms that can reproduce with one another while being isolated from reproducing with other populations.

2

Phylogenetic Concept

The smallest set of organisms that share a common ancestor and can be distinguished from other groups.

3

Recognition Concept

Organisms that can recognized each other as potential mates.

6

Name the 3 types of classification in Taxonomy

1. Monophyletic
2. Paraphyletic
3. Polyphyletic

7

Trichotomies

Clues that are left about an organism that are not sure about its evolutional history

8

Nodes

Common Ancestors

9

Sister Groups

Two groups evolved from the same Nodes

10

What is the difference between Category and Taxon (Taxa)?

Category- D,K,P,O,F,G,S
Taxon- Scientific Names

11

Evolutional Reversal

When a character reverts from a derived state back to the ancestral state over many generations

12

Sexual Selection vs Natural Selection

Sexual- Traits that make mates attracted to them to produce offspring
Natural- Desired traits to help species survive
