Eight criticisms not to make about group selection

Group selection, which was once widely rejected as a significant evolutionary force, is now accepted by all who seriously study the subject. There is still widespread confusion about group selection, however, not only among students and the general public, but among professional evolutionists who do not directly study the subject. We list eight criticisms that are frequently invoked against group selection, which can be permanently laid to rest based upon current knowledge. Experts will always find something to critique about group selection, as for any important subject, but these eight criticisms are not among them. Laying them to rest will enable authors to openly use the term group selection without being handicapped during the review process. [HTML], [PDF]

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]

The Blind Watchmaker applet

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 sons

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]

Gomphotheres, megafauna, and anachronistic fruits

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.

"The field of evolution attracts significantly more speculation than the average area of science."

"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.

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
