Here were some of my findings (I came across a U.Michigan website that summarized some fascinating studies on competition in the evolutionary biology context):
- In answering the first question, it seems natural selection offers two answers. Some plants did not compete with the big guys, simply adapting to living on the forest's floor with less sunlight. Other plants actually used the gargantuan trees, and climbed up them towards the bright sun over the canopy. These very elegant solutions reminded me of small business either positioning in a niche market or partnering with larger firms to leverage their distribution channels.
- The answer to the second question proved much more interesting, as it went to the heart of the studies summarized in the aforementioned website. Findings showed that whenever competition over limited resources existed within any system, all interactions were destructive (ie: no two species could co-exist). The dominant species always exterminated the subordinate one. The key to survival in competition was always adapting to position a species in a way that minimized overlap in resource consumption with the dominant ones. This suggests that adaptation is not a way of survival but the only way to survive, and that diversity is an inevitable state in any perfectly competitive environment.
