Grizzly-Polar bear hybrids in the wild
Timely, Pizzly Bears: Scientists confirmed last week that a bear shot by an Inuvialuit hunter in the Northwest Territories is a second-generation grizzly-polar bear hybrid—a “pizzly” or “grolar” bear. Not that big of a deal. It is likely that polar bears are simply a recent derived variant of brown bear. The main issue not noted […]

I fear the predictable unpredictable. Over the past decade there have been many warnings about Global Warming; precise extrapolations of temperature increases and projections of sea level rise. Such prognostication is understandable, they make the threat concrete to a complacent public. But the reality is that these physical processes are non-linear systems subject to wild fluctuations, with “flips” between alternative equilibrium states. Try to turn that into punchy prose!
Razib Khan: Unlike Singer, Confucius recognised the natural impulse to impose a heirarchy on the value of human life
Unlike Singer, Confucius recognised the natural impulse to impose a heirarchy on the value of human life – and his ideas endured
No one will deny that Peter Singer can provoke. Most recently, in The Life You Can Save, Singer lays out a utilitarian argument for attacking world poverty, extending ideas from his 1971 essay, Famine, Affluence and Morality. Certainly the facts are indisputable, and the logic crisp.
Razib Khan: Darwinism provides a deductive tool, but many of the inferences leave much to be desired in explaining the world as it is
Darwinism provides a deductive tool, but many of the inferences leave much to be desired in explaining the world as it is
“Nothing in biology makes sense except in the light of evolution.” So asserted Theodosius Dobzhansky, to which one might respond that nothing in biology makes sense except in the light of physics. But what has quantum mechanics to do with behavioral ecology? The enthusiasm of many social scientists for the Darwinian paradigm resembles this ontological leap. An evolutionary psychologist may contend that a preference for blondes is the outcome powerful adaptations, how powerful can it be if only a small minority of humans are blonde? Darwinism provides a deductive tool, but many of the inferences leave much to be desired in explaining the world as it is.
Razib Khan: Polygamy may be the natural, though unfair, order of things
Some religions accept polygamy; others abhor it. But in nature, it’s often a case of winner-takes-all-the-wivesAmong mammals a larger proportion of females than males reproduce, the extent of the imbalance signalled by gender differences in size. Eleph…
