Geographical isolation led to the development of a set of new genes in a population of sea lions. these genes created a mutation in their jaws after twenty generations. which mode of evolution does this mutation represent? natural selection macroevolution microevolution

Why was the sample heated in step 5? describe the chemical principles involved in the reasoning behind this step?

Modern whales developed their traits through natural selection what occurs during the process of natural selection

The human genome project is devoted to mapping the general dna sequence of our species. this could lead to the development of new medicines, as well as the possibility of using gene therapy to treat certain diseases. however, there are some ethical issues surrounding the mapping of individual genomes. one concern is a) that your genes may change over time, making the project useless. b) that insurance companies could discriminate based on genetic make-up. c) that since this has never been done before, we should probably not do it now. d) that sequencing our individual genomes is so expensive, it is a counter-productive strategy.
