Question 1

Macroevolution

Answer 1

Evolution at a larger scale across many populations

Question 2

Microevolution

Answer 2

Small changes across a population

Question 3

Speciation

Answer 3

Process for creating new species

Question 4

Species

Answer 4

A group of living organisms consisting of similar individuals capable of breeding/exchanging genes

Question 5

Species Concept

Answer 5

Used to define what a species is

Question 6

Morphological Concept

Answer 6

Characterizes a species based by body shape and other structural features

Question 7

Biological Concept

Answer 7

Group of organisms can potentially interbreed, or mate, with one another to produce viable fertile offspring

Question 8

Reproductive Isolation

Answer 8

Prevents members of different species from producing offspring

Question 9

Prezygotic Isolation Mechanism

Answer 9

Prevents mating and occurs before copulation

Question 10

Ecological Isolation

Answer 10

Species that occur in the same area, but occupy different habitats and rarely interact with each other

Question 11

Temporal Isolation

Answer 11

Species living in the same area that mate at different times of the day/year

Question 12

Behavioral Isolation

Answer 12

When signals of one species are not recognized by another

Question 13

Mechanical Isolation

Answer 13

Different in physical structures make mating impossible

Question 14

Gamete Isolation

Answer 14

When indiviuals of different species mate, but fertilization does not occur because of incompatability between the sperm and egg

Question 15

Postzygotic Isolation Mechanism

Answer 15

Prevents hyrbid offspring from developing/breeding

Question 16

Hyrbid Inviability

Answer 16

Reduces a hybrids capacity to mature into a fit, healthy adult. Cannot survivie to maturity (miscarriage)

Question 17

Hybrid Sterility

Answer 17

Hybrids are sterile

Question 18

Hybrid Breakdown

Answer 18

The second generation of hybrids reduce survival/frttility

Question 19

Speciation

Answer 19

Formation of a new species

Question 20

Allpatric Speciation (Variance)

Answer 20

When one population is geographically isolated form other populations

Question 21

Symatric Speciation

Answer 21

A population develops into 2 or more reproduvily isolated groups without geographic isolation

Question 22

Adaptive Radiation

Answer 22

When many species evolve from a single common ancestor after they are exposed to different enviroments & resoures

Question 23

Population

Answer 23

Any group of individuals of the same species living together in the same area
