Depicts Charles Darwin engaging in a conversation about how a specific cognitive ability may have evolved in humans through natural selection.
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.
