Evolution

Question 1

Allopatric Speciation

Answer 1

Separated or speciation when two same-specie populations separate.

Question 2

Sympatric Speciation

Answer 2

Not separate, or evolution when they inhabit the same area.

Question 3

Life History Strategy (3 things)

Answer 3

1. Growth
2. Maintenance
3. Reproduction

Question 4

Stochastic Environment

Answer 4

Unpredictable environment

Question 5

Terminal Investment

Answer 5

As an organism’s residual reproductive value decreases, its reproductive effort will increase.

Question 6

Intraspecific

Answer 6

Between the same specie

Question 7

Interspecific

Answer 7

Between different species

Question 8

Mutualism

Answer 8

Symbiosis that is beneficial to BOTH organisms involved

Question 9

Predation

Answer 9

Symbiosis where one specie (predator) benefits from the other at the other’s expense

Question 10

Altruism

Answer 10

The actor loses while recipient benefits (full bat feeding other bat) Can it really happen?

Question 11

Commensalism

Answer 11

One specie obtains food or benefits from recipient without either harming or benefiting the recipient

Question 12

Sexual Dimorphism

Answer 12

Differences in appearance between female and male of the same specie.

Question 13

Asexual Reproduction

Answer 13

Offspring arise from a single organism, and inherit the genes of that parent only. (Bacteria)

Question 14

Sexual Reproduction

Answer 14

Organism is created by combining genetic info from two individuals of different sexes.

Question 15

Morphology

Answer 15

Gross structure of an organism and its component parts (physical attributes)

Question 16

Phylogeny

Answer 16

Evolutionary history of a taxonomic group of organisms

Question 17

Fecundity

Answer 17

The natural capability to produce offspring

Question 18

Structure of a Chromosome

Answer 18

Middle= centromere. Tips=telomeres. And the legs are chromatids

Question 19

Vestiges

Answer 19

A trace of something that is disappearing or no longer exists

Question 20

Atavism

Answer 20

A tendency to revert to something ancient or ancestral. (Ancient trait that reappears)

Question 21

Monophyletic Grouping

Answer 21

All come from the same ancestor

Question 22

Paraphyletic Grouping

Answer 22

Group of organisms that includes an ancestor but not all of its descendants. Just a part of the tree

Question 23

Salient Characteristics

Answer 23

The most notable traits of an organism

Question 24

Homolgy

Answer 24

Existence of shared ancestry

Question 25

Analogy

Answer 25

Appear to have shared ancestry, but they don’t (butterfly and birds)

Question 26

Convergent Evolution

Answer 26

The process by which organisms not closely related independently evolve similar traits

Question 27

Homological Evolution

Answer 27

The process by which related organisms evolve similar traits. (Dolphin and human bone hands)

Question 28

Mechanisms of Evolutionary Change

Answer 28

1. Mutation 2. Non-random mating 3. Gene flow 4. Finite population(genetic drift) 5. Natural selection

Question 29

Homonids

Answer 29

Ape family (homo sapiens)

Question 30

Conditions for Natural Selection

Answer 30

1. Reproduction 2. Heredity 3. Variation in organism 4. Variation in individual character
