Should Evolutionary Theory Evolve?
Bob Grant | Jan 1, 2010 | 10+ min read
By Bob Grant Should Evolutionary Theory Evolve? Some biologists are calling for a rethink of the rules of evolution. Evolution, by its very nature, is a dynamic process. But just as fluid are humankind’s efforts to understand, describe, and conceptualize that process. Out went Lamarck, in came Darwin. Mendel’s insights set the rules for genetic inheritance, then certain exceptions to Mendel’s rules materialized. So forth

Surpassing the Law of Averages

By Jeffrey M. Perkel Surpassing the Law of Averages How to expose the behaviors of genes, RNA, proteins, and metabolites in single cells. By necessity or convenience, almost everything we know about biochemistry and molecular biology derives from bulk behavior: From gene regulation to Michaelis-Menten kinetics, we understand biology in terms of what the “average” cell in a population does. But, as Jonathan Weissman of the University of Califo

We can expect that epigenetics will be held up as the forerunner of that bastard child of Creationism, Intelligent Design. The potent wish in the productive hour Calls to its aid Imagination’s power, O’er embryon throngs with mystic charm presides, And sex from sex the nascent world divides… R
