1) You applied for your dream job and just found out you got it. Your contract says that you will be making $30,000 a year. To budget your expenses, you figure
out that your tax rate is 15%, your insurances will be $200 a month, and you want
to put 3% away for your retirement. What is your gross income each month? Net
income (after taxes, insurance and retirement contribution have been taken out)?

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
