Answer:
The correct answer is - punctuated equilibrium.
Explanation:
The phenomena represent punctuated equilibrium, according to which the new well-defined species appear suddenly and quickly. These species remain unchanged for a long time as they occur because of mutations in genes.
This phenomenon suggests that once it made in the fossil record the population becomes stable for a long time until they become extinct and have to adapt to the changes take place to survive.
It depends on their genes if they had an ancestor with Brown eyes
This situation will produce a low birth rate, and likely decrease in individuals. It is a K-selected species.
<h3>K selected species</h3>
K-selected species are species in which the populations fluctuate in values near to the carrying capacity.
These species (K-selected) can be characterized by having long gestation periods, slow maturation and long life spans.
Occasional breeding is also a characteristic of K-selected species.

<span>When we are talking about biogeochemical cycles we are talking about the pathways by which a chemical substance moves through both the biosphere and the atmosphere. There are a number of cycles which come back to the starting point and which can be repeated. Moreover, the very term biogeochemical tells us that there are more than one factor involved. We have chemical, biological and geological factors at play. The circulation of chemical nutrients through the biological and physical world are known as biogeochemical cycles.</span>
