It’s cell type differention, not cell fate determination

terrarium eco system

“…it was only recently (the past 15 years or so) that scientists discovered that a basic set of the same proteins and mRNAs are involved in all of embryogenesis.” This ignores what we described nearly 18 years ago in the…

Did our adapted mind evolve? (Revisited)

human-evolution

Did our adapted mind evolve? In my extended comments on this topic I concluded with “Experience-dependent changes in DNA methylation can exert profound effects on neuronal function and behaviour. A single learning event can induce a variety of DNA modifications…

Behavior: The first response is RNA-mediated not genetically-determined

IMG_2125

Diana Maria Petrosanu asked a question in an Evolutionary Psychology News discussion about Evolution’s Random Paths Lead to One Place. I’ve been very vocal in other discussions that tout ridiculous theories that have been repeatedly refuted by biological facts. My…
