out of a sparrow, a bat, a squirrel, a salt-water fish, and a land snail, the land snail would be the most likely candidate for geographic isolation because it has the least ablilty for mobility and could be blocked off from another area by something as little as some driveway stones or a stream.
What else can I help you with?
What is another name for geographic isolation?
Another name for geographic isolation is allopatric isolation. This refers to a type of isolation where populations become reproductively isolated due to physical barriers preventing gene flow between them.
If two populations have been reproductively isolated and can no longer breed and produce fertile offspring the process of what has occurred?
If two populations of the same species no longer interbreed then their differences will start to become more pronounced and eventually they will become so different that they will be classified as two different sub-species.
How can separation of organisms within the same species lead to the formation of a new species?
When organisms within the same species become isolated from each other, they may evolve independently due to different environmental factors and adaptations. Over time, genetic mutations can accumulate in each isolated population, leading to genetic differences that can eventually prevent interbreeding. This reproductive isolation is a key factor in the formation of a new species.
What is the type of evolution by which organisms evolve differences when they are isolated in different environments?
This type of evolution is known as allopatric speciation, where populations of a species become isolated geographically and evolve independently due to different environmental pressures. Over time, these populations may become distinct species with unique traits and adaptations.
What are some factors that are necessary for the formation of a new species?
reproductive isolation: the gene pools of two populations must become separated for them to become new species. As new species evolve, populations become reproductively isolated from each other.
What process occurs when local units of a population become reproductively isolated from other units?
genetic divergence
What is it called when a population diverges and becomes reproductively isolated?
Speciation
Speciation can result when two populations have become?
reproductively isolated. This can occur through various mechanisms such as geographical isolation, temporal isolation, or behavioral differences. Over time, this isolation causes genetic divergence and leads to the formation of new species.
What three types of barriers that can cause populations to become reproductively isolated from each other?
Isolation can be due to behavioral, geographical, or temporal barriers.
The evolution of reproductive isolation between two or more groups of organisms is?
The origin of new species. To be considered a member of a singe species, organisms must be capable of reproducing and producing viable offspring. Once they have evolved to become reproductively isolated, they can no longer fulfill these requirements and are considered separate species.
What is the process of formation of a new species?
The process is called: speciation. Basically it's when two subpopulations become reproductively isolated from one another and diverge genetically, morphologically and behaviourally.
When is variation most important in evolution?
When the immediate environment changes and stress is put on organisms. Then those who have the variation that will become beneficial in this environment will be reproductively more successful.
What is another name for geographic isolation?
Another name for geographic isolation is allopatric isolation. This refers to a type of isolation where populations become reproductively isolated due to physical barriers preventing gene flow between them.
How can populations become reproductively isolated?
Populations can become reproductively isolated through mechanisms such as geographic isolation (resulting in allopatric speciation), behavioral differences (resulting in prezygotic isolation), or genetic changes that lead to incompatibility between individuals (resulting in postzygotic isolation). These barriers prevent gene flow between populations, leading to their divergence and ultimately speciation.
What must happen for speciation to happen?
A population must be isolated in some way.
If two populations have been reproductively isolated and can no longer breed and produce fertile offspring the process of what has occurred?
If two populations of the same species no longer interbreed then their differences will start to become more pronounced and eventually they will become so different that they will be classified as two different sub-species.
Are frogs r or K selected organisms?
frogs are r-selected because they produce many offspring but only a few of them survive. There is no parental investment and they become reproductively active early in their life cycle.
