Anthro 5 18:02 The Central Problem of Biology Adaptation: Why are organisms so well adjusted to their circumstances? A (small) example: Camouflage Survival as a function of deviations from average size in female song  sparrows. The ones that survive the best are the average sized. What the Heck? How does such adaptive perfection arise…and how is it maintained? It can’t be just “good luck” Too many species, and too many fine-grained traits are involved. Let’s restate the problem… Life:  is organized. o Highly patterned, not random molecules is complex.  o Even single celled organisms Is adjusted to its circumstances. It reproduces. Why? Amazingle, a single theory can explain all these facts at once. This is what makes a theory powerful: its ability to explain many observations  with one idea.
