| What I think is a Greater bird of Paradise (stolen from http://dickeybirds.com/Bird_of_Paradise.htm) |
Well. It seems I'm showing some degree of commitment, or at least more than I'm used to. I guess this is a step in the right direction then. If I can commit to writing down my thoughts then maybe they'll be more inclined to commit to themselves.
I thought of human phenotypic plasticity today.
As humans we usually don't immediately apply the laws of biology that we've discovered to ourselves. But, we're no different and thus are subject to the same principles that underlie all of life. So, I wonder if somewhere in our physiology there is some type of developmental crossroads whereat (is that a word, I don't care) the human body can chose to become suited for climate x or climate y. Maybe in the physiological processes that involve sensitivity to cold or heat. Is a humans tolerance for temperature (or at least their tendency to complain) a reflection of their genetics, or their environment. That is to say, is one's ability to deal with the cold or heat permanent and fixed at birth by my parents contributions to my genome or can it be modulated so as to deal with a person of Nordic descent born in Miami.
I'll have to research this...
I also thought of hair quality as an honest indicator of potential mate health.
In other animals it is common for some elaborate structure to develop almost entirely just to entice a female to engage. (sword tails, birds of paradise) one of the theories is that these structures serve as honest indicators of the overall health of the organism in question.
Is human hair one of these indicators? What other possible significance could hair have possibly served for the past... ~10,000 years?
