Each on diverged from the common ancestor and has its own accumulated mutations. If they have six differences each it would be 10,000 years per one mistake giving you a total of 60,000 years ago.

Answer:

Option B, 60,000 years ago

Explanation:

It is given that the rate of substitution is one substitution per 10,000years

Thus, starting from the base year

Number of substitution after 10,000years = 1

Number of substitution after 20,000years = 2

Number of substitution after 30,000years = 3

Number of substitution after 40,000years = 4

Number of substitution after 50,000years = 5

Number of substitution after 60,000years = 6

Thus, it is clear that 6 substitution or changes will occur in 60,000years.

Thus, option B is correct.

Variation
Differences between individuals in a population.

Adaptations
Any kind of inherited trait that improves an organism's chances of survival.

Natural selection

True or false: competition between organisms involves both biotic and abiotic factors
Mamont248 [21]
I believe it’s true, since Competition will occur between organisms in an ecosystem when both try to use the same resource and the resource is in limited supply. Animals compete for food, water and space to live. Plants compete for light, water, minerals and root space.
