The Great Lakes is an example of a geographic barrier, isolating populations from each other. Populations can become separated (isolated) from one another, as one group expands northward of the lakes and another expands southward of the lakes.
Mountain ranges are geographic barriers that isolate populations from one another, in much the same way as the great lakes.
Oceans geographically isolate land masses, and their respective populations, from one another. This includes islands as well as continents. Examples: the Galapagos Islands, Madagascar, and Australia.
*Geographic isolation is the chief mechanism of allopatric speciation, considered by some to be a theory.

Why would a finch population that lives on an island have a higher rate of speciation that a finch population that lived in a large forest in north America?
A finch population on an island is more isolated than Êa finch population in a large forest. ÊThe gene pool of the island population would be more limited than the genetic possibilities of the finch population in the forest. ÊThe island finches would be more likely to pass on specialized genes than the forest finches. the island finches have more spatial isolation the island finches have more geographical isolation

What does geographic isolation tend to do for a society?
Geographical isolation for a society tends to keep the culture traditional. The isolation for a society also tends to keep the society from the good developments that other societies experience. An example is science and medicine advancements.
Speciation that results from geographical isolation that leads to reproductive isolation?
Allopactric ( other country ) speciation.
What are three ways isolation occur?
1. When new species form.2. When a group is separated from the rest of its species.3. When members of the isolated group can no longer mate with the rest of species.
What geographical feature most influence Japan isolation?
the fact it is on an island.
What is the opposite of geographical?
Non-geographical.
Why do geographical isolation is not regarded as a reproductive isolating mechanism?
Geographical isolation is not a cause of speciation in an asexually reproducing organism because the population is self-pollinating and would be less prone to the factors which results from geographical isolation.
What is the name for a type of isolation that prevents species from interbreeding?
there are six types which are below: 1. geographical isolation 2. ecological (habitat) isolation 3. behavioral (ethological) isolation 4. temporal isolation 5. structural (mechanical) isolation 6. gamete mortality (gamete isolation)
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.
What are three ways that can lead to speciation?
by natural selection, genetic drift and geographical isolation
The separation of populations by barriers such as rivers mountains or bodies of whaters is called?
The separation of populations by barriers such as rivers, mountains, or bodies of water is called geographic isolation. This can lead to the formation of distinct species through genetic divergence and adaptation to their specific environments.
What nation was called Europe's hermit?
Albania. Mainly because of its geographical and cultural isolation.
What are three types of reproductive isolations?
The three types of reproductive isolation are: 1. Temporal isolation: different times of reproduction 2. Behavioral isolation: different habits of the same species 3. Geographical isolation: species are separated by natural barriers
