MANY FALSE STARTS. "Instead of a stair-step, with humans at the top, we stand alongside the kangaroo and the platypus, each of us at the end of its own narrow road. If we look back, into the past, we can see those paths turn and branch and cul-de-sac. Go far enough, and our paths meet at a crossroads. But in between that common ancestor and ourselves, the road is littered with cousins that didn't quite make it." https://lnkd.in/dN-S25a View in LinkedIn

MESSY BIOLOGY. "Biological messiness relates to infidelity, heterogeneity, stochastic noise and variation--both genetic and phenotypic--at all levels, from single proteins to organisms. Messiness comes from the complexity and evolutionary history of biological systems and from the high cost of accuracy. For better or for worse, messiness is inherent to biology. It also provides the raw material for physiological and evolutionary adaptations to new challenges." https://lnkd.in/dA6dYav View in LinkedIn

BOLTED TOGETHER. "Correlated Variation. I mean by this expression that the whole organisation is so tied together during its growth and development, that when slight variations in any one part occur, and are accumulated through natural selection, other parts become modified."

"NATURAL SELECTION acts exclusively by the preservation and accumulation of variations, which are beneficial under the organic and inorganic conditions to which each creature is exposed at all periods of life. The ultimate result is that each creature tends to become more and more improved in relation to its conditions." (Charles Darwin). http://www.bartleby.com/11/4009.html View in LinkedIn

PERFECTLY ADAPTED. "Our textbooks like to illustrate evolution with examples of optimal design—nearly perfect mimicry of a dead leaf by a butterfly or of a poisonous species by a [tasty] relative. But ideal design is a lousy argument for evolution...Odd arrangements and funny solutions are the proof of evolution—paths that a sensible God would never tread but that a natural process, constrained by history, follows…” (Stephen Jay Gould, The Panda’s Thumb).
