The connection between Lamarck, Koestler and communism (actually Stalinism) may be far-fetched to most - but there is merit in considering the ideology of Lamarck and the paranormal science of Jung and Koestler.
Let us assume Cath Ennis is correct - her degrees are adequate. Did she consider how environmental factors such as parents who apply positive thinking and psychic development ideals might in fact strengthen the mutation and even develop it further - to a larger brain like Einstein - or pathways to enable more use of the contents in any brain? I doubt she did. What if a large part of society or a larger social group than the family was INTENT on real spiritual growth? You know - like morality and other weird things. The World Mind is real and transhumanists might even start working to get those sentient robots with human brain contents (Hillis) in a conscious state we can allow a role in Creation.
But about a decade ago Eric Richards was not quite so certain about those DNA required evolutionary aspects as Cath is."A modern epigenetic interpretation of Lamarck's theory would require any epigenetic changes that are passed down to future generations to be stable for many, many generations. Like, hundreds and thousands of generations, to match the slow and gradual pace of evolution. Studies of epigenetic inheritance are still at a pretty early stage, but it seems highly likely that most inherited epigenetic changes will be wiped out within just a few generations.
This makes sense - you'd expect inherited epigenetic patterns to be diluted out pretty quickly by a couple of rounds of reprogramming during the formation of egg and sperm cells, and during embryonic development. Also, other environmental exposures that later generations encounter would be expected to have opposite effects on the epigenome than the original exposure that caused the change in the first generation, which can also wipe out the effects of the inherited change pretty quickly."
"Lamarck, for instance, believed that shore birds acquired their long legs by constantly stretching their legs to lift themselves out of the water and that generations later that kind of environment gave rise to birds with long legs. Neo-Lamarckian views of evolutionary change stress the importance of the environment in altering inheritance.
"When most biologists hear the name Lamarck or the term soft inheritance, the reaction is, 'Oh my God, here we go again'," Richards says. "But from a molecular biology point of view there is a mechanism to do soft inheritance, and epigenetic inheritance can be construed as a form of soft inheritance. That's all I'm saying. The really heretical thing to say is that the environment could be pushing the epigenetic information in a direction that is beneficial. This is the more extreme variation of soft inheritance that raises the hackles."
Epigenetic mechanisms leave DNA sequence unaltered but can affect DNA by preventing the expression of genes. Richards cites a study that shows certain epigenetic alleles can be inherited that affect tumor suppressor genes. His own work in plants has often shown epigenetic information can be inherited. The Richards lab specializes in epigenetics, a biological field that deals with information stored "above and beyond the gene," referring to the Greek meaning of the term."
