The evolutionary theory that suggests that a species can suddenly and rapidly evolve into a new species is ?

1 answer:

6 0

<span>Punctuated Equilibrium/ Equilibria proposes that once species appear in the fossil record, the population will be in the state of little or absent morphologic change. This is called a state of stasis. The theory further proposes that the population is confined to infrequent and geographical rapid events when significant evolutionary change happens. The parent species will the split into two distinct species. This process if called cladogenesis.</span>

cluponka [151]

Answer:

Of the 23 pairs of chromosomes in any normal human cell, the first 22 pairs provide directions for an individual's body and brain development. Scientists now estimate that about half of a person's personality traits and cognitive abilities can be traced to genetic influence and that psychological disorders arise from the interactions of many genes.

Explanation:

Chromosomes are small molecules that have the ability to carry all the genetic information needed to form a living being. These chromosomes are donated by an individual's parents and are used to form 23 pairs that determine all the internal and external characteristics of an organism. Among these 23 pairs, one pair will be responsible for determining the individual's gender, and the other 22 pairs will be responsible for the instructions that will make up the entire body and brain of the individual. Many scientists believe that chromosomes are responsible for even a part of a person's personality traits and that the genes they carry are directly related to the existence of psychological disorders.
