Darwin's Finches became separate species due to
Geographic isolation
Temporal Isolation
Behavioral Isolation
Postzygotic Isolation
The term for the formation of new and distinct species over the course of evolution is...
speciation
biological species concept
reproductive barrier
natural selection
A new river forms and splits two populations, causing ______________ speciation
Sympatric
Allopatric
Extreme
Convergent
Orcas occur in the same habitat but some are avoiding each other and do not interbreed. They have different diets, vocal behavior, and social structures. What type of speciation is this?
Allopatric
Sympatric
Complex
Covergent
04) The biological species concept (BSC) defines a species as:
a. all similar individuals.
b. including all interbreeding populations within a group.
c. members of natural populations that interbreed
d. including all members of actual or potentially interbreeding populations that are reproductively isolated from other groups
A reproductive barrier that prevents mating from ever taking place is a:
Postzygotic Barrier
Prezygotic Barrier
Natural Selection
Species-specific Barrier
A reproductive barrier that prevents mating from occurring due to time is a:
Behavioral Isolation
Temporal Isolation
Habitat Isolation
Mechanical Isolation
Dogs are unable to mate with cats because their sperm/egg cells are not compatible. This is called:
Temporal Isolation
Gametic Isolation
Behavioral Isolation
Habitat Isolation
Sexual selection is when a member of a species chooses a sexual partner based on some external quality. This is an example of:
Gametic Isolation
Habitat Isolation
Hybrid Breakdown
Behavioral Isolation
Reduced Hybrid Viability means:
The offspring cannot reproduce
The offspring cannot hear or see
The offspring will most likely die due to complications
The offs ping will be part of a new species
Reduced Hybrid Fertility means:
The offspring cannot reproduce
The offspring cannot survive outside of its nest
The offspring will die young
The offspring will never grow
Which is a main characteristic of a postzygotic barrier?
It causes slow development of an embryo
No embryo will be formed
An offspring will be born, but it will struggle to survive/reproduce
If the reproductive organs of two individuals cannot come into contact with each other, the barrier is considered to be:
Gametic Isolation
Temporal Isolation
Mechanical Isolation
Reduced hybrid Viability
