If the map ratio of a map is 1:100000 and the distance between two places on the map is 8cm, find the actual distance between the two
places.
​

Given that,

Map scale = 1:100000

Map distance = 8cm

Therefore,

MD ÷ AD = 1 ÷ 100000

8 ÷ AD = 1 ÷ 100000

AD = 8 × 100000

AD = 800000

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.
