The social discussions show enthusiasm for the study, with many posts emphasizing how early mammals' increase in body size was the first step before brain enlargement, using words like 'excited,' 'favorite,' and references to specific scientific methods like CT scans. These elements reflect a positive reception and curiosity about evolutionary processes, with some sharing links and celebrating collaborations, indicating moderate engagement and perceived significance.
AgreementModerate agreement
Most discussions acknowledge and support the findings, highlighting that body size increase preceded brain size development in early placental mammals.
InterestHigh interest
Posts demonstrate high curiosity, with many referring to interesting details about mammal evolution and using phrases like 'interesting read' and 'excited to share,' indicating engaging content.
EngagementModerate engagement
Participants actively reference specific studies and utilize scientific terminology, evidencing a moderate depth of involvement.
ImpactModerate impact
The widespread sharing of the research and naming of influential scientists suggest the discussion has some influence on understanding mammal evolution, but primarily within academic and scientific communities.
Abstract in brief
Early placental mammals initially decreased their relative brain size after the extinction event because their body size increased faster than their brain size.
During the Eocene, several lineages of placentals independently evolved highly developed brains by expanding sensory regions, indicating a shift toward brain growth.
The initial increase in body size was driven by filling ecological niches post-extinction, while larger brains emerged later as ecosystems became crowded and competition grew.]
Contrary to the convention that mammal brains have steadily enlarged over time, a new Science study finds body sizes among placental mammals were the first thing to increase after the animals expanded across the globe after the dinosaurs’ extinction. https://t.co/pPmA9gvdjI https://t.co/xcV1cGE86d

“It was only later, in the Eocene, that brain size began to increase, likely driven by a need for greater cognition in increasingly complex environments” Or: because of less affordances for offloading the basis of cognition into the environment! https://t.co/EunHTYfWtp

“…placental radiation initially emphasized increases in body size…Brains eventually became larger as ecosystems saturated and competition intensified.”
