Almost 100 years of a barley common garden experiment involving reciprocal crossing showed a rapid decrease in genetic diversity with around 60% of progeny deriving from a single parent after 50 generations. @evogen.bsky.social Paper: doi.org/10.1126/science.adl0038 (24/34)
Natural selection drives emergent genetic homogeneity in a century-scale experiment with barley
Direct observation is central to our understanding of adaptation, but evolution is rarely documented in a large, multicellular organism for more than a few generations. In this study, we observed evol...

I think we've got to think of these feed additives as a partial solution. Their effects will make an immediate dent in emissions while we make incremental, but permanent improvements via genetic selection (which may be our best strategy for reaching grazing cattle that make up the beef herd).

Good stuff as always John! Always takes some reprogramming/reframing to address a clear problem with unclear economic signals (see also: methane emissions)

Better late than never. When I saw @johnbcole.bsky.social and @hoffsbeefs.bsky.social I knew all was right in the world

Realizing now how much science was missing from my feed on the other site. Super refreshing!

I blow a lot of freshmen Animal Science students' minds with that (but sub cow in for antelope). Great way to kickstart their thinking about evolution!
