Teo Gibson via Facebook asked:

Is there anything discovered to date which might explain how instincts are encoded in DNA like spiders doing certain things with their webs and certain human behaviours for example?


Stefanie: -   There are some human behaviours that are definitely hard-wired in the genetic code.  Like the fear of heights, from living in trees and having to hold on, or fear of darkness coming from the fear of being eaten by a predator.  I think there are some genes that we know are involved in this, but I think its still a question scientists are working on today.
