Is there evidence to support this, or is it just Internet speculation? For example, do we know what traits would favor someone in a jungle? Have you lived in a jungle or researched the question?
Do we know how evolution works? One thing I believe I understand is that evolution takes far longer than people imagine. A few centuries is nothing. Humans have been in their current evolutionary form for around 200,000 years. Adaptations are not evolution, and our genetics change and adapt during our lifetimes. My children will not be genetically better at typing than the original homo sapiens. Think of that: You are not genetically smarter than humans of 200,000 years ago; someone then is just as able to be a scientist as you are. All of our advantages are from other factors.
Another thing I've learned is that claims need evidence; that's what separates the wheat from the infinite chaff, the science from the witchcraft. The parent comment would require evidence to qualify for even a high school essay.
