The inability of organisms to evolve anything that could be an advantage reflects _____.

sergey [27]

The inability of organisms to evolve anything that could be an advantage reflects "the limit of historical constraints".

<h3>What is the limit of historical constraints of evolution?</h3>

Although evolution is a powerful process that leads to

rapid changes in the characteristics of organisms, limits

to evolution arise from a lack of genetic variation, a

loss of well-adapted genotypes in populations due to

gene flow, trait interactions leading to trade-offs, and/

or the difficulty of evolving simultaneous changes in a

number of traits. This is the limit of historical constraints of evolution.

<h3>What are the factors that can cause an organism to evolve?</h3>

Four main factors lead to evolution:

(1) the potential for a species to diversify;

(2) heritable genetic variation among individuals within a species as a result of mutation and sexual reproduction;

(3) competition for scarce resources; and

(4) the spread of organisms that are better able to endure and procreate in the environment.

Decreasing the rate of gene flow between two populations is likely to make the populations more different from one another. true

devlian [24]

The given statement "Decreasing the rate of gene flow between two populations is likely to make the populations more different from one another." is False.

Gene flow refers to the processes by which genes are transferred from one group to another.
Gene flow, which is a term used more frequently in anthropology, refers to the allelic change brought on by human movement.
Gene flow would reduce the isolation that could lead to speciation by increasing population similarity and reproductive kinship.
Gene flow significantly slows down speciation by recombining the gene pools of the groups and therefore repairing the growing variations in genetic variation that would have otherwise resulted in full speciation and the creation of daughter species.
