A species of birds lives in a particular niche. As their population increases, many of these birds migrate to new niches with di
fferent food sources. In niches where hard seeds and nuts are the main food sources, the birds with stronger beaks succeed and grow in population. In niches where small insects and larvae are the main food sources, the birds with longer, narrow beaks succeed and grow in population.
This is an example of how
A.
genetic engineering leads to less diversity.
B.
genetic engineering leads to more diversity.
C.
natural selection leads to less diversity.
D.
natural selection leads to more diversity.
Natural selection is the biological phenomenon in which the environment fits a population to its environment. The individuals that are better adapted to a particular habitat niche are a more competitive advantage in the struggle for resources and have increased chances of passing down their genes to the next generation.
Explanation:
Birds with stronger beaks out-compete the other birds for nuts and hard seeds hence dominate this niche. The birds with longer narrow beaks out-compete other birds for small insects and larvae hence dominate in this niche too. Over time the different subspecies are fitted into their niches by natural selection.
