If two sub-populations of a species become reproductively isolated, it means that adaptation or genetic drift can make the two populations diverge genetically. If, as a result of this divergence, upon reintroduction, members of the two sub-populations no longer reproduce successfully, the two sub-populations have become different species.

Hybrid zones provide an opportunity to investigate?
The evolution of reproductive isolation
How does environment relate to evolution?
The environment is the natural selector.
Why is isolation important in evolution?
It is the reproductive isolation between populations that allows divergence between populations, and ultimately speciation, to occur. Often this reproductive isolation is the result of geographical isolation, for instance when part of a population migrates to new territories.
How did Darwin relate Malthus's ideas to evolution by natural selection?
By science
What is a mutation and how does it relate to evolution?
A mutation is any change in the DNA. Mutations provide the genetic variation that evolution by natural selection needs to select from.
Type of isolation that led to the evolution of the kaibab squirrel?
Geograpic isolation

How do mutations natural selection geographic isolation genetic drift and migration contribute to biological evolution?
they contribute to biological evolution by how they've affected the evolution rate by increasing it or decreasing it
How is the structer of the cerebrum thought to relate to the evolution of human intelligence?
It isn't

What is the type of evolution by which organisms evolve differences when they are isolated in different environments?
Allopatric speciation.Allopactric speciation. Geographic isolation. Adaptive radiation can also result from geographic isolation.
Which term refers to the study of human fossil remains and how they relate to human evolution?
Paleoanthropology is the term that refers to the study of human fossil remains and how they relate to human evolution. This field combines aspects of anthropology and paleontology to understand the biological and behavioral evolution of the human species.
Difference between the evolution of man and the evolution of apes?
Man is an ape. The evolution of one is the evolution of the other. Genetics in a particular immediate environment and reproductive isolation leads to the variences in two species that share very recent common ancestors.
When studying evolution the term isolation means one?
D, Population becomes seperated from another population.
Explain the evidence of evolution presented by the mammals of Australia?
the mammals of Australia evolved in isolation on the Australian continent
