Latest Lamarckism Stories
The domestication of chickens has given rise to rapid and extensive changes in genome function. A research team at Linköping University in Sweden has established that the changes are heritable, although they do not affect the DNA structure. Humans kept Red Junglefowl as livestock about 8000 years ago. Evolutionarily speaking, the sudden emergence of an enormous variety of domestic fowl of different colours, shapes and sizes has occurred in record time. The traditional Darwinian...
Salk scientists discover 'hidden' code in DNA evolves more rapidly than genetic code A "hidden" code linked to the DNA of plants allows them to develop and pass down new biological traits far more rapidly than previously thought, according to the findings of a groundbreaking study by researchers at the Salk Institute for Biological Studies. The study, published Sept. 16 in the journal Science, provides the first evidence that an organism's "epigenetic" code - an extra layer of...
Early 20th century evolutionist may have discovered epigeneticsA new study into the research of the renowned Lamarckian experimentalist Paul Kammerer may help to end the controversy which has engulfed his research for almost a century. The study, published in The Journal of Experimental Zoology, suggests that far from being a fraud Kammerer may have discovered the field of epigenetics, placing him decades ahead of his contemporaries.Paul Kammerer, a leading proponent of the Lamarckian theory...
Article reviews evidence for epigenetic inheritance in wide range of speciesFor years, genes have been considered the one and only way biological traits could be passed down through generations of organisms.Not anymore.Increasingly, biologists are finding that non-genetic variation acquired during the life of an organism can sometimes be passed on to offspring"”a phenomenon known as epigenetic inheritance. An article forthcoming in the July issue of The Quarterly Review of Biology lists...
German scientists say they have discovered cabbage looper caterpillars are able to alter the expression of their genes in response to plant bacteria. The scientists, led by Dalial Freitak at the Max Planck Institute for Chemical Ecology, determined the caterpillars (Trichoplusia ni) alter their genes associated with metabolism, homeostasis and immunity. And as well as tailoring gene expression within their own digestive systems, the caterpillars pass the information to their offspring....
