When a subpopulation of a species is separated from another part by any form of geographical isolation the differences between individuals becomes more important to the traits of later offspring. Particularly if the isolated population has significantly fewer members than the population left behind.
If there are traits among the survivors that are asynchronous to the percentages in the original population, then the offspring may be more likely to carry those traits and thus the population may eventually shift to all have the same trait that was rare in the original population.
This is very important when dealing with environmental dangers. If the species is isolated in a colder environment, those members that survive cold better may live longer and be able to reproduce more. Their offspring, specifically those who carry traits that allow them to survive the cold easier, will survive and reproduce and their offspring may all have the trait. The original population that was left behind may not even look like the new species if the trait that was passed on was "longer hair" or "fuller feathers" or "thicker skin."
What else can I help you with?
In which area would a population be geographically isolated?
A population would be geographically isolated in areas such as islands, mountaintops, or remote valleys where physical barriers like oceans, mountains, or deserts prevent easy gene flow with other populations.
What happens to the 2 subgroup after being geographically isolated from each other?
Depending on what the animals' climates were like, each sub-species would begin to develop different characteristics to help them survive in their environment. For example: if one sub-species lived in the mountains and the other in the desert, the mountain group would probably develop something like sure-footedness, while the desert group would be more likely to adapt to go for longer periods of time without water.
When members of a species become separated by geography and lose ability to interbreed how would scientists classify them?
They would become 2 separate species.
When members of a Species become separated by geography and lose the ability to interbreed how would scientist classify them?
They would become 2 separate species.
What would happen if all individuals in a species were sterile not able to have babies?
If all individuals in a species were sterile the species would become extinct
What is isolation in relation to human evolution?
If a group of humans were kept completely isolated for tens of thousands of years, their genetics would gradually mutate to adapt to their surrounding environment, as according to 'natural selection'. Eventually, they would become a new species, unable to breed with the old one.
Without reproduction would a species become extinct?
True
Why do madagascans plants and animals do not exist in any other part of the world?
Madagascar is a geographically isolated island ~500 km off the southeastern coast of Africa (Mozambique). This isolation is too far from shore for land animals to reach. This isolation, much like Australia, led to isolated evolution with few predators. Much like you would not see Koalas anywhere else than Australia; you will not see lemurs naturally occurring anywhere but Madagascar. Exception - some bird species found in Madagascar are found elsewhere.
Why were ancient Greek communities isolated from one land?
The mountain ranges in Greece would create vallies where citys were built. Because the mountains were very hard to travel over they isolated the city to develope individully from the other citys making them city-states.
Do grizzlies neutur there young?
No. If they did, the species would quickly become extinct.
What would happen if fertilization no longer occurred in a species that reproduces sexually?
It would become extinct.
What are organisms that only mate with their own kind called?
Organisms that only mate with their own kind are called "reproductively isolated" or "reproductively compatible" species. This behavior helps maintain genetic integrity within a species and prevents hybridization with other species.
