The role of history in how efficient color names evolve
The role of history in how efficient color names evolve
In a new study, biology and psychology researchers show how existing color vocabularies constrain future options for efficient color vocabularies.
More than skin deep: A molecular and mechanistic look at pigmentation variation
More than skin deep: A molecular and mechanistic look at pigmentation variation
A new collaborative study offers a better understanding of genes and variants responsible for skin color, providing insights into human evolution and local adaptation.
Neanderthals carried genes acquired from ancient interactions with ‘cousins’ of modern humans
Neanderthals carried genes acquired from ancient interactions with ‘cousins’ of modern humans
A new collaborative study led by Sarah Tishkoff shows that Neanderthals inherited at least 6% of their genome from a now-extinct lineage of early modern humans.
Conflicts and cultural evolution: All for one and one for all?
Conflicts and cultural evolution: All for one and one for all?
Researchers from the School of Arts & Sciences show that, when it comes to learning and honing different skills, what’s better for the individual isn’t always better for the group.
The evolution of societal cooperation
The evolution of societal cooperation
Research led by the School of Arts & Sciences’ Joshua Plotkin and Taylor Kessinger sheds light on the impact of social contexts and multilayered societies on promoting cooperative behavior.
How species partnerships evolve
How species partnerships evolve
Biologists from the School of Arts & Sciences explored how symbiotic relationships between species evolve to become specific or general, cooperative, or antagonistic.
An arms race that plays out in a single genome
An arms race that plays out in a single genome
School of Arts & Sciences biologist Mia Levine and Cara Brand, a postdoc, shed light on an example of coevolution in fruit flies that has implications for human health.
Rapid adaptation in fruit flies
Rapid adaptation in fruit flies
New findings from School of Arts & Sciences biologists show that evolution—normally considered to be a gradual process—can occur in a matter of weeks in fruit flies in response to natural environmental change.
Context-dependent behavior can make cooperation flourish
Context-dependent behavior can make cooperation flourish
Recent studies led by School of Arts & Sciences’ researchers show that changing social strategies between settings—for example, cooperating at home but not at work—can in fact lead to more cooperative behavior in a society.
From corals to humans, a shared trigger for sperm to get in motion
From corals to humans, a shared trigger for sperm to get in motion
Coral sperm require a specific pH to move, according to research from the School of Arts & Sciences, which identifies a signaling pathway that is shared by organisms including humans. The results inform how corals may fare with climate change.
