Inheritance of Acquired Characteristics

Post  pinhedz on Sun Jul 05, 2015 1:38 am

The book was written by Paul Kammerer in 1924, and was later embraced by the Nazis.

Kammerer killed himself.

A similar theory in the Soviet Union was called "Lysenkoism."

The theory is now, of course, dismissed by all who subscribe to politically propriety.

Until now--the WashPost just published an article on "non-genetic evolution." Shocked Shocked

It seems that the first to make the claim that acquired characteristics can be inherited was made by Jean-Baptiste Lamark (1744-1829). Since the theory did not seem consistent with Darwin’s writings on natural selection, Lamarckism doesn’t have much credibility these days.

Also, it is not politically correct, if you think about it, because it suggests that educated people will have smarter children, and that parents without college educations will have intellectually inferior children. And the Nazi’s liked this idea—not a good thing for future credibility.  

Major 20th-century investigators of Lamarckism were Paul Kammerer in Germany and Trofim Lysenko in Russia. Kammerer experimented with amphibians and Lysenko with grain.

Kammerer did some very convincing experiments, showing that lizards who changed color during their lifetimes for camouflage purposes could pass their new color on to their offspring. But he was accused of faking some results of experiments on frogs, and then killed himself.

Wiki says that Trofim Lysenko, while working at an agricultural experiment station in Azerbaijan, published a paper on vernalization, which drew wide attention because of its potential practical implications for Soviet agriculture. Severe cold and lack of winter snow had destroyed many early winter-wheat seedlings. By treating wheat seeds with moisture as well as cold, Lysenko induced them to bear a crop when planted in spring. Lysenko coined the term "Jarovization" to describe this chilling process, which he used to make the seeds of winter cereals behave like spring cereals ("Jarovoe"). However, this method was already well-known to farmers since the 1800s, and had recently been discussed in detail by Gustav Gassner as "vernalization" (from the Latin "vernus", of the Spring).

Lysenko's exaggerated claims for massively increased yields were based on plantings over a few hectares, and he further incorrectly claimed that the vernalized transformation could be inherited – i.e., that the offspring of a vernalized plant would themselves go on to flower more quickly, with the vernalization treatment.

But that’s all history now. The latest findings—on non-genetic inheritance of obesity—will now be told. Shocked

Here's the latest:

The WashPost says "We Can't Blame Obesity on our Genes," even if there is a correlation between obese parents and obese children. It turns out the inheritance is "non-genetic." Suspect

The search for "obesity genes" has failed. If fat parents choose a lean surrogate mother, the baby won't be born fat.

The claim is that lean mothers compete with their babies for fat, so they have leaner babies. After the lean babies are born, they run around and become olympic athletes, while the fat babies sit in front of the TV drinking beer and eating chips and dip until they get diabetes, and their babies are born in worse shape than they were--the proverbial vicious circle. Neutral

btw--Paul Kammerer also seriously studied what is known as "The law of seriality," which casts doubt on the reality of coincidence. He was a very interesting person. study

I just happened that the pinhed was talking about Kammerer when Mikulsy made her profound philosophical statement. Coincidence? Suspect
