Acquired traits may also be inherited to the next generation, or even generations.The idea that qualities acquired from experience can be transmitted to future offspring has long been considered incompatible with current understanding of genetics. However, the recent documentation of non-Mendelian transgenerational inheritance makes such a "Lamarckian"-like phenomenon more plausible. Here, we demonstrate that exposure of 15-d-old mice to 2 weeks of an enriched environment (EE), that includes exposure to novel objects, elevated social interactions and voluntary exercise, enhances long-term potentiation (LTP) not only in these enriched mice but also in their future offspring through early adolescence, even if the offspring never experience EE. In both generations, LTP induction is augmented by a newly appearing cAMP/p38 MAP kinase-dependent signaling cascade. Strikingly, defective LTP and contextual fear conditioning memory normally associated with ras-grf knock-out mice are both masked in the offspring of enriched mutant parents. The transgenerational transmission of this effect occurs from the enriched mother to her offspring during embryogenesis. If a similar phenomenon occurs in humans, the effectiveness of one's memory during adolescence, particularly in those with defective cell signaling mechanisms that control memory, can be influenced by environmental stimulation experienced by one's mother during her youth.
Yes, pretty much anyone who has seriously studied biology and Genetics at a credible university within the past 20 years SHOULD know this was possible!
This is a case of someone taking what might be credible science and then making an illogical statement about what it proves.
All this study is REALLY saying is that this chemical can affect the mind early on. This seems to indicate influences can come perhaps earlier than thought. Also, it addresses a specific change by this specific substance. However, it is nothing really radical, not at all.
This is precisely what happens with radiation. It is what happens with many chemicals.
I have to wonder where you found this? Most science journals would have ensured it were worded differantly.
