ELIZABETH KOLBERT: There is definitely evidence that humans have continued to evolve in response to a changing diet — for example lactose tolerance in adults is a pretty recent trait that's arisen a few times in societies that raised cows.
This work complements prior genetic linkage maps [ 19- 22], recent trait-focused studies [ 24- 26], and enriches prior macrosyntenic alignments of T. repens with Medicago[ 22, 34, 35].
Many studies suggest that recent trait-based and phylogenetic approaches are effective for disentangling these questions relating to forest community structure (HilleRisLambers et al. 2012).
Recent trait-assignment studies have shown that fireprone floras likely existed in Australia [ 7, 8] and the Cape of South Africa [ 9, 10] earlier than that (up to 60 Ma) coinciding with the appearance of fire-adapted traits.
This could suggest a second possible scenario in which the class II pilE locus is ancestral in N. meningitidis and the class I pilS/ pilE locus is a more recent trait which has arisen in specific lineages.
In contrast, studies of the mitochondrial genome indicate that the large but highly fragmented structure, again a feature of this taxon, is a more recent trait as it is common to the dinoflagellates and O. marina but probably not to Perkinsus [ 8].
Agnosy's most recent album, Traits of the Past, came out back in 2014; I haven't heard many peeps from them since then, but they've bene playing regularly, and mentioned on Facebook that they were working on a new album, so now is the perfect time to acquaint yourselves with one of the greats.
Recent quantitative trait loci (QTL) mapping studies in several agricultural systems have suggested that QTL affecting fitness traits are often clustered in the genome, suggesting tight physical linkage or pleiotropic effects on several components of fitness [ 9- 14], but the ubiquity of this result across experimental populations and environments is not well understood.
Recent multi-trait analyses at different phenotypic levels are uncovering the pleiotropy and the genetic regulation underlying high-level complex traits.
Far from being part of our cultural DNA, emotional restraint was a relatively recent national trait.
