Select one form of SPECIATION and share your rendition of thisprocess of speciation. You can upload a drawing you have made oryou can list the steps that occur. Once again mutationwhich provides variation is at the heart of the process. Mutationis the engine that runs evolutionary change. IF VARIATION IS NOTPRESENT IN THE ORIGINAL POPULATION THERE IS NO VARIETY AVAILABLE TOADAPT TO THE NEW ENVIRONMENT AFTER THE CHANGE IN THE HABITAT OCCURS. IF YOU SAY THAT THE CHANGE IN THE ENVIRONMENT MAKES A MUTATIONHAPPEN YOU WILL NOT RECEIVE CREDIT - BECAUSE THIS IS NOT CORRECT.MUTATIONS OCCUR RANDOMLY - NOT ON DEMAND
Make sure you account for this in your rendition.
By this I mean, you must show that a mutation has randomlyoccurred in the species prior to any other stepsoccurring. Once again showing the steps in theprocess is what is important here.
Draw or list each step in an example of speciation.
Allopatric speciation is just a fancy name forspeciation by geographic isolation,
Peripatric speciation is a special version ofthe allopatric speciation model and happens when one of theisolated populations has very few individuals.
Sympatric speciation does not requirelarge-scale geographic distance to reduce gene flow between partsof a population. Merely exploiting a new niche mayautomatically reduce gene flow with individualsexploiting the other niche.
In parapatric speciation, Individuals are morelikely to mate with their geographic neighborsthan with individuals in a different part of the population’srange.
