Allopatric Speciation
How is sympatric speciation similar to allopatric speciations?
allopatric speciation happens when a physical barrier divides two populations of the same species and sympatric speciation happen when no physical barrier divides the member of a population, but methods such as polyploidy (chromosome doubling) do not let the members of the species have fertile offspring, 2 species are formed (the parental "normal" species and the divergent species "polyploids"). Remember that a species is defined as a population that when mated with one another produce fertile offspring. A polyploid and a parental organisms can not produce fertile offspring together so they become two different species and speciation is said to have occurred.
How did the continental shift theory affect evolution?
The ultimate allopatric ( geographic ) speciation. If you had a population of quite similar organisms in a area that split the population into two or more populations when continental drift occurred you would have different mutations and changing environments putting selective pressure on two or more populations now.
Different geographic populations of a species differ in some characteristics but are uniform in many other characterswhat is the reason for this uniformity?
Allopatric speciation. Initially both species are the exact same. But when separated by geographical barrier, they develop adaptations for the new environment. Survival of the fittest results in different genes being selected for. New gene pool results in a new species that are almost similar but reproductively isolated.
Resource partitioning would be most likely to occur between?
sympatric populations of species with similar ecological niches
What is the process in which similar species become disimliar?
It's called Speciation.
Are copper and silver similar or different?
They are different elements but they are similar in that they are both metals.
