Researchers compared Neandertal and modern human pelvises, finding that the male pelvis evolved a unique biomechanical shock-absorbing mechanism that stores energy and facilitates long-distance walking. This innovation likely arose from the need to cushion the impact of each step and release energy with every stride.
The Neandertal growth hormone receptor has been found to increase muscle mass in people today, with carriers having around 270 grams more muscle mass on average. This effect is most pronounced in individuals of South and East Asian descent.

This gap is attributed to genetic differences, reproductive strategies, and parental investment, which provide a survival advantage to females.
Researchers discovered that humans with Indigenous American ancestry are more likely to carry a variant of the MUC19 gene inherited from Denisovans, which may have helped them adapt to new ecosystems. The Denisovan gene variant is surrounded by DNA from Neanderthals, suggesting interbreeding between the two species.
Researchers found that behavioral flexibility is related to exploration and dispersal in great-tailed grackles. Individuals with greater flexibility exhibit more exploratory behavior, which facilitates their ability to adapt to new environments and expand their geographic range.

A study of fossil teeth from a 56-million-year-old extinct predator reveals how animals adapted to extreme climate change. The findings suggest that limited food played a bigger role in the dietary shift than just hotter temperatures.
A new study found that early humans consumed carbohydrate-rich foods like grains and underground plant tissues before they had the ideal teeth to chew them efficiently. This suggests that behavior played a significant role in their physical evolution, allowing them to adapt to new environments despite physical limitations.
A new study has coined the term 'scrumping' to describe great apes' fondness for eating ripe, fermented fruit from the forest floor. The researchers suggest that this behavior may have played a significant role in the evolution of human alcohol tolerance.
Researchers found that people who experienced malnutrition early in life may have survived threats like plague at greater rates until young adulthood. However, this survival advantage could drop significantly when entering middle and late adult years.
