How have humans impacted the evolution of animals?

Are humans inadvertently driving evolution in other species? Mounting evidence suggests activities such as commercial fishing, angling and hunting, along with the use of pesticides and antibiotics, are leading to dramatic evolutionary changes.

Why is human variation important to the survival of the human species?

When genetic variants confer a particular advantage and improve our fitness they are more likely to survive and be passed onto future generations, thus becoming more common in a population. When this happens, a pattern or ‘signature’ can be found in the genomes of the population.

What causes dehumanization?

Dehumanization often occurs as a result of intergroup conflict. Ethnic and racial others are often represented as animals in popular culture and scholarship. There is evidence that this representation persists in the American context with African Americans implicitly associated with apes.

While human phenotypes may seem diverse, individuals actually differ by only 1 in every 1,000 base pairs and is primarily the result of inherited genetic differences.

How does dehumanization affect?

Denial of Human Uniqueness is related to forms of interpersonal maltreatment that affect our status relative to others. Being treated as incompetent, unintelligent, unsophisticated, and uncivilized results in aversive self-awareness and self-blame, leading to feelings of guilt and shame.
