Hey everyone,
I am monitoring Trends
in Genetics this semester for our class.
I found a paper released on Monday February 18th that is sort
of relevant to some of our class discussions (FOXP2 gene, transposon
mutagenesis and scientists bashing the works of other scientists are found here).
In a nutshell, this paper was a response to a paper by
Gerald Crabtree, who claimed that our human intellect is inevitably declining
over time due to retrotransposition events that cause a loss of heterozygousity
in a beneficial variant of neuron-related genes. Crabtree claims that this, therefore, makes
intellect less heritable. This paper
proves that there is no link between changing intellect and heritability.
