Niche diversity refers to the evolutionary process in which species diverge in order to take advantage of open niches in their environment. This can also be seen in species that are somehow threaded from a common ancestor they share.Hope this helps:)
The scientific name for white oak is Quercia Alba and the scientific name for red oak is Quercia Ribera, this tells us that both the species are closely associated because of the fact that they are in the similar genus. A genus refers to a principal taxonomic category, which ranks below family and above species, and is signified by a capitalized Latin name.
This also suggests that all of their taxonomic groups are similar from domain to genus. The more common taxonomic groups exhibited by the organisms, the more closely they are associated.
N an experiment, suppose that the wings of fruit flies were clipped short for fifty generations. The fifty-first generation emerged with normal-length wings. This observation would tend to disprove the idea that evolution is based on
a. inheritance of natural variations
b. inheritance of acquired characteristics
c. natural selection
d. survival of the fittest
Inheritance of acquired characteristics. Thus, option "B" is correct.
<h3 /><h3>What is inheritance of acquired characteristics?</h3>
For fifty generations wings of fruit flies were clipped. Hence they acquired this trait in their lifetime and not genetically. If acquired characteristics were capable of passing on to next generation, 50 generations would have been enough to inculcate this clipped wing trait in fruit flies. Despite it, the fifty-first generation did not have clipped wings.
Hence evolution can not occur without genetic variation. A character simply acquired in a lifetime does not create a difference in germ cells and hence is not enough to be passed on to next generation or cause evolution
