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.

Maru [420]

Answer:

In a particular case of secondary succession, three species of wild grass all invaded a field. By the second season, a single species dominated the field and the other two species had a lower relative abundance. A possible factor contributing to the abundances of these species in this example of secondary succession is <u>inhibition</u>.

Explanation:

Trees are great examples of allelopathy in plants. Some use their allelochemicals to inhibit germination or impede development of nearby plant life. Most allelopathic trees release these chemicals through their leaves, which are toxic once absorbed by other plants. Black walnut is a prime example of this.
