These are groups of reproducing populations that are isolated from other groups?

the answer is SPECIES BECAUSE the common definition is that of a group of organisms capable of interbreeding and producing fertile offspring of both genders, and separated from other such groups with which interbreeding does not (normally) happen. Other definitions may focus on similarity of DNA or morphology.

What is one cause of speciation?
One cause of speciation is reproductive isolation or the separation of the population of a species from other populations so that it can change without keep getting mixed with other populations( and therefore becoming identical to other populations).
The situation of populations by barriers such as rivers mountains or bodies of water is called what?
Populations can become geographically isolated by barriers such as mountains or rivers. These barriers reproductively isolate the populations by restricting or preventing gene flow between them, leading to genetic divergence. Other kinds of geographic features, such as roads, canals, and even agricultural fields can have similar effects.
What happen when organisms populate a new area and are isolated geographically from other populations of the same species?
The species will eventually evolve to be similar, but not exactly like the main species.
Groups of populations that interact with each other in a given area are called?
Several populations make up a community. Communities interact with the non-living world around and make up an eco-system.community cousin.
How does geographic isolation contribute to the evolution of a new species?
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 are groups of reproducing populations that are isolated from other groups?
These groups are called "reproductive isolates," and they play a key role in the process of speciation by preventing gene flow between populations. Reproductive isolates can result from factors such as geographic barriers, behavioral differences, or genetic incompatibilities.
What is Linnaeus's description of a species?
Linnaeus defined a species as a group of organisms that can interbreed among themselves to produce fertile offspring. He used a system of binomial nomenclature to give each species a unique two-part Latin name, consisting of the genus and species names.
Which idea explains Darwin's observations about galapagos Islands finches?
Biological Species Concept, which defines species as groups of interbreeding populations that are reproductively isolated from other groups.
What happens when a population is isolated into two or three groups?
Actually, nothing happens. But if the distances increase between the groups, then they become geographically diverse and hence there will be a greater chance of development of a new species from the isolated groups. Other factors also influence this, like the presence of already existing populations in the new area.
What is reproduction species?
Species are community of populations that are reproductive isolated from other and that occupy a specific niche. Such sister species can live in sympathry.
Do horned toads live in groups or alone?
Amphibians are not herd animals. Toads and other amphibians live alone except when they are reproducing.
What is believed to be the dominant mode of speciation among most groups of organisms?
The dominant mode of speciation among most groups of organisms is allopatric speciation. This occurs when populations of a species become geographically isolated from each other and over time, genetic and environmental differences accumulate, leading to the formation of distinct 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.
What is reproductive species concepts?
Species are community of populations that are reproductive isolated from other and that occupy a specific niche. Such sister species can live in sympathry.
What is one cause of speciation?
One cause of speciation is reproductive isolation or the separation of the population of a species from other populations so that it can change without keep getting mixed with other populations( and therefore becoming identical to other populations).
Can two groups become different species if they are not reproductively isolated from each other?
Yes. As an example, a species may come in two varieties that differ in appearance. Many animals prefer to mate with individuals that resemble them. Sexual selection can therefore cause two populations to diverge.
Groups of populations that interact with each other in a given area form a community. true or false?
true
