A recent study published in Journal of Evolutionary Biology found that male bighorn sheep have distinct personalities, influencing their survival and reproductive success. Younger, more aggressive rams often reproduce but die younger, while older, more docile peers survive longer.
A study published in Cortex found that Parkinson's patients struggle with grammatically complex sentences due to degeneration of dopamine-secreting neurons. Eye-tracking data revealed slower response times when processing relative clauses, but not at the end of sentences.
Researchers have rediscovered a dormant human gene, IRGM, which was thought to be extinct for millions of years. The study, published in PLOS Genetics, reveals that the gene was resurrected through a complex series of structural events, suggesting its potential importance in fighting new or resistant infectious agents.
Researchers found that females were more often chosen as leaders of intragroup conditions while males were preferred to lead intergroup situations. Female leaders were also viewed as being more effective in maintaining positive relationships within the group.
Researchers found that adults and young children can rapidly identify snakes among harmless images, but struggle with detecting them in cluttered environments. This innate ability may be linked to our ancestors' survival and reproductive success.
Researchers have speculated that the Foxp2 gene is linked to language ability, but MIT's Robert Berwick argues this connection is unlikely due to complexity and speculative chain of events. Language is likely the result of a subtle interplay among various factors, making direct genetic connections impossible.
Researchers have discovered a key difference in the way gastrulation occurs between higher vertebrate species and less evolutionarily advanced animals. The study reveals that higher vertebrates acquire a new mechanism of 'cell intercalation' to position their axis at the midline, distinguishing them from fish and other lower vertebrates.
Research suggests that the ability of humans to use social cues in cooperative situations may have evolved since the human lineage split from chimpanzees. In contrast, domestic dogs display an innate ability to solve social problems without prior training. This capacity is thought to be linked to the process of dog domestication.
A newly discovered gene, HAR1F, has undergone accelerated evolutionary change in humans and is active during critical brain development stages. The gene's role in cerebral cortex development and expansion during human evolution remains speculative but exciting.
Research reveals that human T cells lack expression of certain 'Siglec' molecules, which regulate T cell activation in nonhuman primates. This absence may contribute to the disparity in disease susceptibility between humans and great apes. The study highlights the potential for Siglecs to act as a 'brake' on T cell activation.
A recent study has found that human and chimp molecular evolution rates are surprisingly similar, indicating that certain human-specific traits such as generation time may have evolved only one million years ago. This slowdown in the molecular clock correlates with a longer generation time, which is also characteristic of humans.
Researchers found evidence that specific variants of a bitter-taste receptor gene were strongly favored in early human evolution, leading to increased sensitivity to toxic compounds. This suggests a pivotal role for bitter-taste perception in toxin avoidance in humans.
Researchers explore whether male fireflies' flashing lights have evolved to provide uninformative cues about male quality. They also examine the energy required for these displays and its potential impact on human communication.
Recent baboon studies provide insights into the complexity of monkey social behavior and suggest that natural selection has favored sophisticated social intelligence in primates. This research may inform theories concerned with the evolution of human language and cognition.
