...Wilder also spoke directly with Gene Orza of the players association. Orza advised him to hold off on any education about supplements until more information was available. Wilder was incredulous. Of Orza's request to postone any action, the doctor wrote, "That will be never! Orza and the Players Association want to do further study ... so nothing will be done...
...tests are the same, which leads to picking a minimum IQ and calling it genius-level. Also, estimates of the IQs of dead geniuses tend to be fun, but they are based on biographical information that can be highly uneven. (Read TIME's 1999 cover story about the "I.Q. Gene...
...intricate that they probably put some limits on evolution's creative potential. Once a lineage of animals evolves networks for arms and legs, it's not easy for evolution to rewire the networks to produce, say, wheels. For one thing, many networks share some of the same genes. A change to a gene that improves one network may wreck another one. So for the most part, we're stuck with what evolution gave...
Biologists have documented a vast amount of gene-swapping among single-celled organisms - which happen to make up most of the diversity of life on Earth. There are 10,000 species of bacteria in a spoonful of dirt, twice as many species as all the mammals in the world. In the genome of a typical microbe, most of the genes hopped from one species to another at some point in the history of life. In some ways, the history of life is indeed like a tree, sprouting new branches. But in some ways, it's also like a tapestry, emerging...
...into a new vision of evolution known as the Modern Synthesis. Today a number of biologists argue that it's time for a new understanding of evolution, one that Pigliucci has called the Extended Evolutionary Synthesis. For now, they are fiercely debating every aspect of that synthesis - how important gene-swapping is to the course of evolution, for instance, and how gene networks get rewired to produce new traits...
