"Neither Lysenkoism or Lamarckism is anywhere close to being accepted." says who ? you ,lolol Several recent studies, one conducted by researchers at MIT and another by researchers at the Tufts University School of Medicine, have rekindled the debate once again. As reported in MIT's Technology Review in February of 2009, "The effects of an animal's environment during adolescence can be passed down to future offspring ... The findings provide support for a 200-year-old theory of evolution that has been largely dismissed: Lamarckian evolution, which states that acquired characteristics can be passed on to offspring." In May 2009 it was reported that Cabbage looper caterpillars (Trichoplusia ni) can alter the expression of genes associated with metabolism, homeostasis and immunity after feeding on plants carrying bacteria. Research published in BioMed Central's Frontiers in Zoology has shown that, as well as tailoring gene expression within their own digestive systems, the insects are able to pass this information along to their offspring. This would appear to be an instance of Lamarckian evolution.
