∙ 9y agoSpecies are based on differential genetics resulting in reproduction within and amongst themselves (in general). If two organisms can produce viable offspring, that who is they themselves can reproduce the requirements to definition of a species are met.

∙ 12y agoA viable population of one species must be separated from others of the same species for a time with no chance of cross-breading. This could occur on islands, on the other side of a desert or mountain range. A change in the local environment could speed the process if the separated group is able to adapt to new food sources but this is not necessary.

Which of the following can result in instant speciation?
Allopatric speciation and sympatric speciation are two factors. Allopatric speciation occurs when physical barriers are formed, separating the specie. This will cause the specie to evolve at different rates causing a new specie to form. Sympatric speciation is less likely to occur when comparing it to allopatric. In sympatric speciation is no longer physical but generic. For example a mutation in the genetic order of the specie (which does not happen as often as physical barriers), and a different mating preference/season.
Speciation without geographic isolation is called what?
Sympatric Speciation develops within the range of the parent population. This type of speciation does not include geographical isolation, and can occur rapidly if a genetic change results in a barrier between the mutants and the parent population.
Which of the following shows an example of organisms being classified based on their physiological abilities?
Speciation occurs during the evolutionary development, or phylogeny, of a species. In which of the following situations will speciation occur
What usually has to happen before a population can become 2 different species?
Allopatric Speciation usually must happen
What is phyletic speciation?
Divergence
What is necessary for speciation to occur?
Isolation Is necessary for speciation to occur.
What situations will speciation occur?
Speciation is the process of a new species developing. Speciation can occur from a geographical split in the species, Species can split in the same area if they start depending on different foods.
How long it takes for speciation to occur?
several generations
What type of speciation occur when a plant population becomes reproductively isolated while living with its parent population?
Sympatric Speciation
How did speciation occur in the anoles of the Caribbean?
Specific ecological niches
What must happen for speciation to happen?
A population must be isolated in some way.

What happen when the range of an animal species becomes divided?
Speciation.
What effect would a very short generation time such as bacteria have on speciation?
Well they would evolve faster, so speciation would occur faster too
What best describes how long it usually takes for speciation to occur?
species originate through allopatric speciation

Speciation occurs during the evolutionary development, or phylogeny, of a species. In which of the following situations will speciation occur
