Talk:Living fossil
From RationalWiki
Funny that I was thinking about whether we had this or not today in the car, even composing a few paragraphs in my head, to discover not only that we do have it, but that it was created yesterday! ħuman

[edit] New section for currently known mechanisms?
I added this text tonight:
- Today, the mechanism is known: when selection pressure is lessened, or favors traits the organism already possesses to be successful in the current niche, stabilizing selection occurs, which favors the existing, successful body plan; stabilizing selection is the opposite of disruptive selection.
I wanted to know what you thought of whether a new, short section should be added. The mechanism also hold true for all other organisms in a steady-state non-selective pressure environment requiring adaptation which brings traits towards the mean. Kassorlae (talk) 06:25, 1 June 2014 (UTC)
