While the discussions delve into scientific details, they mainly influence academic curiosity rather than broader societal change, leading to a moderate score.
Abstract in brief
The study found that birds have nearly twice as many bone-associated genes under positive selection compared to mammals, indicating strong evolutionary pressure linked to flight adaptation.
Most positively selected genes in birds are related to bone regulation, remodeling, and functions like bone metabolism and muscle development, which are critical for powered flight.
The patterns of genetic evolution suggest that there was a period of intense selection for improved flight efficiency, which also influenced changes in body size and bone structure.]
Powered flight evolved independently in birds & bats but followed similar evolutionary paths. For instance, in both cases, there were strong constraints & positive selection on genes related to body size & skeletal structure (Machado et al. 2016). #2023MMM https://t.co/ghy5TXS4zG https://t.co/FOodfdwlbH
