100

When organisms move in or out of a population

What is gene flow

100
Group of individuals capable of breeding and producing viable offspring
What is Biological Species Concept
100

Speciation event due to reproductive isolation when populations are overlapping

What is Sympatric Speciation

100

a form of macroevolution demonstrated in the predator/ prey relationship

What is coevolution?

100
Change in a species over time
What is evolution or macroevolution
200
Appearance of lots of species over a short period of time
What is adaptive radiation?
200

The difficulty in identifying species using fossil specimens is a limitation of which species concept

Biological species concept

200

A type of reproductive isolation due to different breeding seasons

What is temporal isolation?

200
Creates homologus structures
What is divergent evolution?
200
A species evolves due to another species evolving
What is coevolution
300

Random changes in allele frequencies

What is genetic drift
300
Group of individuals with similar characteristics
What is Morphological Species Concept
300

A type of reproductive isolation due to different mating rituals

What is behavioral isolation?

300
Creates analogous structures
What is convergent evolution
300
Creation of species due to geographic barriers
What is allopatric speciation
400

Changes in gene frequencies occur following the separation of fish in a flash flood from the main population and subsequently establish a new population in the nearby lake.

The founder effect

400

Analogous structures are a limitation of which species concept

Morphological species concept
400

A type of reproductive isolation due to different reproductive structures

What is morphological isolation?

400
Explains why a whale has five finger bones in its fin
What is divergent evolutions
400
Two species acquiring same characteristics from different ancestral species
What is convergent evolution
500

Red feathers are a common color in a population. Suddenly, a volcano erupts and kills more than 3/4 of the population. Now green feathers are more common.

What is the effect demonstrated?

What is the bottleneck effect

500

Species defined as a branch in a taxonomy tree

What is the phylogenetic species concepts?

500
Speciation due to reduced hybrid viability
What is post zygotic isolation?
500
A bat wing and an insect wing are an example of this type of evolution
What is convergent evolution?
500

The change in allele frequencies that occurs over time within a population. This change is due to four different processes: mutation, selection, gene flow and genetic drift.
