The Price of Altruism - George Price, a (troubled) father of group selection thru his discovery of the eponymous Price Equation, has a rather interesting biography... [more inside]

This is a fun little atheistic distraction: The interactive Blind Watchmaker applet demonstrates how random mutation followed by non-random selection can lead to interesting, complex forms. The Blind Watchmaker algorithm was conceived by Richard Dawkins and is described in his book of the same name. The resultant forms (which can begin to look like plants and bugs) are called "biomorphs," visual representations of a set of genes. [more inside]

Billionaires have more grandchildren through their sons than through their daughters, because the status advantage is more reproductively valuable to the sons. Therefore, it would be adaptive for the mothers of their children to bear more sons than daughters. But surely that can't be; mothers can't control the sex of their children. Oh but so it is: billionaires have 60% male children. [more inside]

Osage orange, avocado, papaya, honey locust, paw paw, persimmon, and many more: fruits that have outlasted the gomphotheres and other megafauna. These "anachronistic fruits" can be a key to understanding their intended consumers. More. More. More. And even more.

"Nothing in biology makes sense except in light of evolution." Despite Theodosius Dobzhansky's succint description of natural selection at the core of biological research since Darwin's fateful trip to the Galapagos, evolutionary biologist Michael Lynch respectfully dissents, asking "whether natural selection is a necessary or sufficient force to explain" the complexity of multicellular organisms we see today, where mutation, recombination and genetic drift are often overlooked, but critical factors in evolutionary theory and understanding.

In nature, mothers aren't so motherly.

How cocky was your great^10 grandfather? Up to 3 million men may be descended from an Irish King. Impressive but still well short of the estimated 16 million ancestors of Genghis Khan. Does the alpha male mojo that drives leadership also make a man a horndog or does being a high status male simply give one the opportunity that all men would gladly have? If you aren't constantly on the lookout for a new hen, perhaps you're not presidential material.

Mothers who wait to have a baby are at risk of evolutionary extinction. "If you want to see your line persist, then it's probably optimum to start reproducing in your early to mid-20s". According to this 220 year statistical model late-reproducing women [genetic lineage] declined as a proportion of the population from 11 percent to about 5 percent

Thrown off the scent. A fascinating story about The Pill and its effect on women's mate choice, and the effect of these choices on evolution. T-shirts belonging to unknown men were given to women to smell. All they had to do was say which smelt best. Women on the pill chose exactly the opposite t-shirts to those that didn't - find me free will, personal taste and the nature / culture divide in that if you can...
