Why is the mating between the closely genetically related Chimpanzees (Pan troglodytes) and Bonobos (Pan paniscus) so different?

All Things AAFS!

Taken from an assignment in which I was set the task to combat a controversial question and then create a conference paper on the topic for a Primate Behavioural Ecology unit. This is a comparative approach of factors that could attribute to the differences, and not a definitive answer – just my analysis of theories/my own conclusion.


Primates, Pan troglodytes and Pan paniscus, both speciated from a shared last common ancestor, yet they have very different mating behaviours. Pan troglodytes are known for their aggressive behaviour, even when it comes to mating. Pan paniscus on the other hand are known to perform sexual activities for purposes other than reproduction. There are many social, physiological and environmental factors which could have caused this diverse approach to reproduction. Within this paper I will be utilising past research, conducted on these contributing factors, to theorise why these primates have created two different…
