Researchers found elevated selection and increased mutational burdens in wild emmer wheat under global warming, but also more beneficial mutations. Genetic responses vary by temperature and rainfall, with high temperatures associated with lower mutational burden and reduced selection.
New research suggests that societal complexity is linked to personality traits, with more complex societies exhibiting greater diversity of personality types. This is explained by the presence of multiple socioecological niches, which shape individual behavior and contribute to success or reinforcement within a given environment.
