Separate 72 into 2 parts, one of which shall be 1/3 of the other

The second part of 72 is

Step-by-step explanation:

The whole part is given  as  = 72

One part of it = 1/3

Let  the other part of it  = k

Now,according to the question:

First Part + Second Part = 72

or,

⇒

or,

or, k = 215/3

Hence, the second part of 72 is

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.
