Darwins Theory of Evolution

When Niles Eldredge and Stephen Jay Gould, two of the world's leading evolutionary theorists, proposed a bold new theory of evolution - the theory of "punctuated equilibria" - they stood the standard interpretation of Darwin on its head. They also ignited a furious debate about the true nature of evolution. On the one side are the geneticists. They contend that evolution proceeds slowly but surely, driven by competition among organisms to transmit their genes from generation to generation. On the other are the paleontologists, like Eldredge and Gould, who show in the fossil record that in fact evolution proceeds only sporadically. Long periods of no change - equilibria - are "punctuated" by episodes of rapid evolutionary activity. According to the paleontologists, this pattern shows that evolution is driven far more by environmental forces than by genetic competition. How can the prevailing views on evolution be so different? In Reinventing Darwin, Niles Eldredge offers a spirited account of the dispute and an impressive case for the paleontologists' side of the story. With the mastery that only a leading contributor to the debate can provide, he charts the course of theory from Darwin's day to the present and explores the fundamental mysteries and crucial questions that underlie the current quarrels. Is evolution fired by a gentle and persistent motor and fueled by the survival instincts of "selfish genes"? Or does it proceed in fits and starts, as the fossil record seems to show? What is the role of environmental changes such as habitat destruction and of cataclysmic events like meteor impacts? Are most species inherently stable, changing only very little until they succumb toextinction? Or are species highly adaptable, changing all the time? Eldredge sorts through the major findings and interpretations and presents a lively introduction to the leading edge of evolutionary theory today.

Darwin and Evolution for Kids traces the transformation of a privileged and somewhat scatterbrained youth into the great thinker who proposed the revolutionary theory of evolution. Through 21 hands-on activities, young scientists learn about Darwin's life and work and assess current evidence of evolution. Activities include going on a botanical treasure hunt, keeping field notes as a backyard naturalist, and tying knots for ship sails like those on the HMS "Beagle. Children also learn how fossils are created, trace genetic traits through their family trees, and discover if acquired traits are passed along to future generations. By encouraging children, parents, and teachers to define the differences between theories and beliefs, facts and opinions, Darwin and Evolution for Kids does not shy away from a theory that continues to spark heated public debate more than a century after it was first proposed.

Neutral theory of molecular evolution - The Neutral theory of molecular evolution (also, simply the neutral theory of evolution) is an influential theory that was introduced with provocative effect by Motoo Kimura in the late 1960s and early 1970s. Although the theory was received by some as an argument against Darwin's theory of evolution by natural selection, Kimura and most evolutionary biologists today maintain that the two theories are compatible.

Evolution Sex Theory - Since the Human Genome Project was completed in 2003, many theories based on the findings (or lack thereof) have come to light. The Evolution Sex Theory states that humans are given genetic instructions to be male or female and to have sex with the opposite sex in order to reproduce.

Near-Extinction evolution theory - Futurist writer Allan Silliphant produced a television documentary in 1996 titled " Near Extinction, The Core of Evolution" which proposed and explained his concept of a central mechanism of mammalian, primate. and even human evolution.
