Abstract

Analysis of the interaction between mortality patterns and opportunity for natural selection could help to elucidate potential evolutionary implications of epidemic mortality. In this paper secular trends are studied in relation to Crow's index (I^sub t^) and its components of mortality (I^sub m^) and fertility (I^sub f^), using parish records for family reconstitution in a Basque population. A principal components analysis (91% of the variance accounted for) showed marked qua...

Discover ; IS NATURAL SELECTION THE PRIME mover behind evolution? Darwin's great insight into the mechanics of evolution was that a population of creatures always has a lot of variation - more feathers here, less fat there, more urge to kill there - and some of these variations allow the individuals bearing

The Independent on Sunday ; Everyone knows that the theory of evolution by natural selection was discovered in England, by Charles Darwin and Alfred Russel Wallace. In this book Marek Kohn goes on to show that the theory was preserved, nurtured and developed here when the rest of the world didn't want to know. Even Darwin, it

A gambler's model of natural selection
The American Biology Teacher ; It is difficult to intuitively grasp how chance in the evolutionary process can lead to complex ends. To quote Darwin: To suppose that the eye with all its inimitable catrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of
Letter: Competition and natural selection
The Independent - London ; Sir: I am delighted to see a digestible and coherent explanation of evolution aimed toward the uninitiated, but David Bodanis (The DIY University; "Evolution", 7 August) has risked misleading his readership on one or two important points. First, Charles Darwin's autobiography makes clear that he
A hands-on exercise to demonstrate evolution by natural selection & genetic drift
The American Biology Teacher ; Although students "learn" (i.e., hear about) the components of evolution by natural selection in high school biology courses, few of them truly understand or remember them. We have developed an interactive, hands-on method of teaching about natural selection that we think increases the

Chicago Sun-Times ; A smart trainer will often tell his jockey to break in front and then improve his position, if the horse is capable.
