This evidence supports the claim that some emotional reactions may occur without conscious thinking.
Thalamus is a small brain area located above the brain stem, with the main function of sending motor and sensory signals from the spinal cord and the mid-brain structures to the cerebral cortex.

Amygdala is a small brain region, which is part of the limbic system. It is considered the emotional control centre of the brain since it regulates emotions, survival instincts and some memory functions.

It has been proven that visual input is directly sent by the thalamus to the amygdala, which can trigger some emotional responses (such as fear) without any conscious processing.

Elephant seals are abundant in their population size but they have low genetic diversity within their species due to overhunting
Anastasy [175]
<h2>Genetic diversity </h2>

Explanation:

If the environment changes, the species runs the risk of not having the genetic diversity to be adaptable to that change and could go extinct

  • Genetic diversity is the diversity  or genetic variability within species
  • The huge variety of different gene sets defines an individual or a whole population's ability to tolerate stress from any given environmental factor
  • While some individuals might be able to tolerate an increased load of pollutants in their environment, others carrying different genes might suffer from infertility or even die under the exact same environmental conditions;the former will continue to live in the environment the latter will either have to leave it or die
  • Any change in the environment - natural or human induced causes a selection of events that only the fittest survive
  • In case of elephant seals,overhunting reduces the sum of genes available,thus leaving behind a population that is less capable of tolerating any further natural or human disturbances in environment
  • The loss of genetic diversity within a species can result in the loss of useful and desirable traits
