Joshua is trying to decide if there is a relationship between a driver's age and the number of traffic tickets they get. he surveys 150 people in three towns and records their age, many traffic tickets they got in the last year, and the town they live in. he creates a graph of his data. what is the independent variable?

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.
