Which of the various species concepts identifies species based on the degree of genetic exchange between their gene pools?
Biological species concept :)
How is species defined as the biological species concept?
Organisms are the same species if the have the potential, or actually interbreed one with another. Does not apply to all organisms. Bacteria being an example of this. Is not as strong a concept as once it was as it did not adequately address hybridization.
How does speciation affect evolution?
Speciation is the process by which new biological species arise. It is part of the evolutionary process; how two or more populations of one species, when separated geographically, can gradually change over time in different ways, to become separate species.
Is a competition between two species for food symbiosis relationship?
A symbiotic relationship is a close and often long-term interaction between different biological species.
What is the difference between anatomical anomaly and biological variation?
Biological variation is much wider term. It takes place at the level of species while anatomical anomaly means a anatomicaly different individual within species.
How organisms assigned to biological species?
Biological species consists of groups of populations. Populations are assigned to the same biological species based on their ability to interbreed and produce fertile (viable) offspring.
What is the relationship between biological 'island ' size and the number of species that can live there?
The smaller the island the fewer species that can live there. The smaller their populations can be the more vulnerable they are to further disturbance or climate change.
What is clining?
In biological terms it is the change in certain characteristics of populations of organisms of the same species
At what point are two populations descending from the same ancestors considered separate species?
When they have reproductive isolation. This happens when either physical or biological barriers prevent reproduction between the two populations. At that point, their mix of genes will be significantly different that they will be considered two new species.
Which of the various species concepts identifies species based on the degree of genetic exchange between their gene pools?
Biological species concept :)
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 are the differences between the morphological species concept biological species concept and phylogenetic species concept?
The morphological species concept differentiates species by their physical traits, basically. The biological species concept defines a species as generally organisms that breed with others of the same species; rather a genetic isolation concept. The phylogenetic concept is based on evolutionary relationships and is the concept used by cladists.
Can Southern African San people and Australian Aborigines have a fertile offspring?
Of course the can. Humans are one species under the biological species concept and all populations of humans can interbreed.
What is ecological competition?
The simultaneous demand between two or more species-populations for a resource that is not abundant enough to support all of them at the sizes they would attain in the absence of the other species-populations.
When most populations of a wide ranging amphibian species are lost and the few remaining populations are widely separated you expect to see that?
gene flow between populations is reduced
Describe how a population differs from a species?
There is one big difference between a population and a species. Populations do not necessarily have to refer to living things whereas species does.
How is species defined as the biological species concept?
Organisms are the same species if the have the potential, or actually interbreed one with another. Does not apply to all organisms. Bacteria being an example of this. Is not as strong a concept as once it was as it did not adequately address hybridization.
