Storyboard Text

  • Good evening! In today talk I propose that the human ability of emotion and recognition of emotions is a product of natural selection and the work of evolution
  • But what do those factors mean?
  • This event would have required the need for three factors, those being variation, inheritance and selection
  • For a trait to be selected for requires that there be a variety of those traits available in the population. There must have been a variety of emotional capacities in our early ancestors.
  • Next, inheritance or the ability to pass on this trait to an offspring must be possible. Thus this increased capacity for emotion must have been passed on from parent to child.
  • But what kind of adaptive advantage might this cognitive ability have provided?
  • Finally there must have been some selective pressure on our early ancestors that enabled those that were more emotional and expressive to succeed better.
  • Recognizing emotions is adaptive in a social group, especially in the complex structures that our species is capable of forming.
  • I propose that this capacity to be emotional and recognize emotions was advantageous to our ancestors because it helped them form better bonds in social structures, thus increasing their reproductive success.
