Trend lines can be used to make
predictions in real-world situations.
Three methods for making trend lines
are:
method (by hand)
• divide-center method (by hand)
regression (with
technology)

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.
