What characterizes speciation in new areas, such as a recently formed island? a- rapid speciation occurs as populations adapt to the environment. b- speciation cannot occur in a new area until a particular habitat forms. c- speciation occurs extremely slowly and gradually, as new species arrive on the island over hundreds of thousands or millions of years d- a single species typically inhabits the island for thousands of years before other speciation occurs.

A-rapid speciation occurs as the population adapt to the environment.

Explanation: Speciation can be defined as the phenomena in which new species evolve from the existing parent species. The speciation can occur because of geographical barriers between the members of the same species, behavioral isolation and reproductive isolation.

In the given situation, a recently formed island may separate the population of the same species. The geographical barrier will prevent the members of the species to copulate. Hence, the separated members will adapt the changes in the new habitat and they will evolve to be developed into new species.

Therefore, rapid speciation occurs as the population adapt to the environment is the correct option.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

2%? i tried finding the exact sorry if it's not 100% correct ; -;
