You're missing my point. My point is that evolution happens in a subset of whole population. Sometimes it goes so far that a new species are created.
So, different populations of same species are expected to have evolved different subtle traits.
I don't think that Portia too carry eggs in their fangs. Nothing points to that as I recall.
- undersuit 10y agoYou're missing my point, maybe because I veered off into musing on how an egg sac detection trait could be a gene. I'm trying to say that the development of what almost looks like a learned behavior but is possibly a geographically isolated gene is more surprising than the modification of a gene so that it is expressed past childhood. We see the latter all the time in other forms if you look at domesticated animals as we have selected for the cute and cuddly traits for adult animals that are normally present in infant forms.
