the answer is in page 497 starts where it says over several and ends where it says isolated population...
Here is the answer more specific..... It contributes because isolated groups may experience different environments then other species somewhere else where so they will have to adapt to there environment to survive..for example if you put a bird on one island and a bird on another island farther away with a different environment they are both gonna adapt to there environment and become 2 different species
Good answer but i think mine might be a little more informational. Also i got this answer in the McGraw Hill Glencoe life science book on page 159 bottom left.
Geographic Isolation contributes to evolution because many gene mutations occur. A species has already adapted to that cold environment so that they will change. This will cause the organism to not be able to mate with any other of their old species. This also adds variations to populations. The Key deer, for example, evolved because of geographic evolution 4,000-6,000 years ago. Now the key deer will only be able to mate with other deer that went through the same mutations in geographic evolution.
What else can I help you with?
Does geographic isolation contribute to evolution-?
A geographic barrier eg mountain range, river, ocean, desert, can split a species into two populations which can no longer mix with each other. By splitting up a species into two separate populations a geographic barrier can lead to the formation of a new species. The two separate populations start to develop in isolation from each other. Different mutations will occur in the two populations and natural selection will adapt them to the slightly different conditions in the two areas. Given enough time the two populations will become so different that if they are brought together again they will no longer be able to interbreed ie they will have become two different species. This is called allopatric speciation.
How did the separation of earth's continents affect biological evelution?
The separation of Earth's continents has influenced biological evolution by creating geographic isolation. This isolation has led to the development of unique species in different regions through divergent evolution. It has also allowed for the exchange of species between continents, leading to evolutionary changes through processes like adaptation and speciation.
What type of speciation occurs when new species arise as a result of geographic isolation?
When a certain species is divided up into two or more separate populations (geographically, for example) they continue to evolve (via natural selection) and over time the two (or more) populations will be so different from each other that they will not be able to reproduce, and will fit the criteria of different species.
What is a process of forming new species by evolution from preexisting species?
The process of forming new species from preexisting species is called speciation. It typically occurs when populations of a species become reproductively isolated from one another, leading to genetic divergence and the eventual evolution of distinct species. Speciation can happen through various mechanisms, such as geographic isolation, behavioral differences, or genetic mutations.
How does evolution produces new species?
Evolution produces new species through a process called speciation, where populations of a species become reproductively isolated from one another, leading to the accumulation of genetic differences over time. This can occur through mechanisms such as geographic isolation, genetic mutations, and natural selection, ultimately resulting in the emergence of distinct species that can no longer interbreed.
What were the elements for the formation of new species?
The formation of new species typically involves factors such as geographic isolation, genetic mutations, natural selection, and reproductive isolation. These elements contribute to genetic divergence between populations, eventually leading to the evolution of unique characteristics and the formation of distinct species.
When studying evolution the term isolation means one?
Isolation in evolution refers to the separation of a population from the rest of its species, leading to reduced gene flow between different groups. This isolation can be geographic, reproductive, or behavioral, and can ultimately result in the development of distinct species through the process of divergent evolution.
What does geopraphic isolation mean?
Geographic isolation refers to the physical separation of populations of a species by a barrier such as a mountain or body of water, preventing them from interbreeding. Over time, this isolation can lead to the evolution of distinct species due to the lack of gene flow between the separated populations.
How do you use geographic isolation in a sentence?
"Japan used Geographic isolation more than once" Is a sentence using Geographic isolation.
What does geographic isolation prevent?
Geographic isolation prevents individuals of the same species from interbreeding and exchanging genes, leading to the formation of distinct populations. Over time, this can result in the evolution of new species with different characteristics and adaptations.
Does geographic isolation contribute to evolution-?
A geographic barrier eg mountain range, river, ocean, desert, can split a species into two populations which can no longer mix with each other. By splitting up a species into two separate populations a geographic barrier can lead to the formation of a new species. The two separate populations start to develop in isolation from each other. Different mutations will occur in the two populations and natural selection will adapt them to the slightly different conditions in the two areas. Given enough time the two populations will become so different that if they are brought together again they will no longer be able to interbreed ie they will have become two different species. This is called allopatric speciation.
What is the difference between geographic isolation and convergent evolution?
Geographic isolation refers to the physical separation of populations, leading to independent evolution due to limited gene flow. On the other hand, convergent evolution describes when unrelated species develop similar traits or characteristics due to adapting to similar environmental pressures, despite not sharing a recent common ancestor.
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 species have evolved due to geographic isolation?
Some examples of species that have evolved due to geographic isolation include the Galapagos finches, Hawaiian honeycreepers, and the marsupials of Australia. Geographic isolation can lead to the development of distinct traits and adaptations in isolated populations over time, eventually creating new species.
What species did Darwin find on the Galapagos Islands?
Geographic isolation of a common ancestral species of finches
What account for the diversity of millions of species on earth?
The diversity of millions of species on Earth is mainly due to evolution through natural selection, where genetic variations within populations lead to different adaptations to specific environments over time, resulting in the emergence of new species. Additionally, factors such as geographic isolation, environmental changes, and ecological interactions also contribute to the diversification of species.
How did the separation of earth's continents affect biological evelution?
The separation of Earth's continents has influenced biological evolution by creating geographic isolation. This isolation has led to the development of unique species in different regions through divergent evolution. It has also allowed for the exchange of species between continents, leading to evolutionary changes through processes like adaptation and speciation.
