Scientists develop an evolutionary theory of stress

[ad_1] Scientists have created an evolutionary model to predict how animals should react in stressful situations. Almost all organisms have fast-acting stress responses, which help them respond to threats, but being stressed consumes energy and chronic stress can be harmful. The new study by an international team, which includes researchers …

Same visual system for all primates

[ad_1] The smallest primate in the world reveals the incredible preservation of our visual system through millions of years of evolution. The gray mouse lemur, the smallest species of primate, has excellent eyesight. More than a fifth of its cerebral cortex is devoted to visual processing to accommodate enough pixel …

Scientists predict “optimal” stress levels

[ad_1] Scientists have created an evolutionary model to predict how animals should react in stressful situations. Almost all organisms have fast-acting stress responses, which help them respond to threats, but being stressed consumes energy and chronic stress can be harmful. The new study – led by an international team that …
