Answer:

Four central postulates that emerges from Charles Darwin and Russel Wallace are detailed below. As there is no option provided in the question hence any option beyond the meaning of these four points will not be from these four postulates.

Explanation:

The four postulates were:  

  1. More individuals are produced each generation than can survive.
  2. Phenotypic variation exists among individuals and the variation is heritable.
  3. Those individuals with heritable traits better suited to the environment will survive.
  4. When reproductive isolation occurs new species will form.

<u>1st:</u>

The number of individuals produced in a generation of a specie is more than that of the ones who survive. Some of them cannot withstand the environmental conditions and die.

<u>2nd:</u>

Observable characteristics of an individual can vary and this variation is inherited by parental cells/genes.

<u>3rd:</u>

The individuals who have characteristics which are suitable to the environment exists and survives while other ones do not bear the environment and die soon.

<u>4th:</u>

Reproductive isolation is the evolutionary mechanism which prevents members of different species from producing offspring but whenever this occurs, most of the times, new specie is formed. The survival of this new specie again depends upon suitability of its characteristics with environment.

The message refers to which of the following?
Oliga [24]

The message is the information being communicated from one place to another.

It used to be called the "intelligence".  But as time went on, it became
harder to ignore the obvious fact that that was going too far, and the
label was changed to the more IQ-neutral "message".
