Question

GEOGRAPHICAL and reproductive isolation of organisms gradually leads to speciation.

Answer 1

Nature drives for a portfolio of broad and diverse investment.

It plays the market, as we well know but it does get rid of forces that will ultimately oppose any one of its directions.

Any variation in the composition and history of a thing, and you get something else, which might grow closer or further from the point of its origin.

Take the relative geographical isolation of bipedal apes that we know of for example. The DNA reached the same agreements but the deal couldn't survive in differing contexts.

Untold and immeasurable variables constantly flowing with but a few constants. It's surprising that life hasn't diversified further than speciation.
