In spite of these and many other evident differences, social insects and humans have conquered the earth because they share two characteristics: a highly developed system of social cooperation, and a complex division of labor. These observations prompt two questions: If there are evident evolutionary...
The main hypothesis that emerges from this overview is that crying evolved as an emotional expression that signals distress and promotes prosocial behaviors in conspecifics. Further, shedding tears may influence the mood of the crier and his/her outlook on life primarily as a consequence of ...
To approach a question 400 million years in the making, researchers turned to mudskippers, blinking fish that live partially out of water.
If monkeys and humans evolved from a common ancestor, why did we evolve differently? How do mutation, migration, and genetic drift cause the evolution of populations? Be specific and provide examples of all three cases. What is biological evolution? a. the development of traits that organism...
Humans have evolved an exceptionally high metabolic rate, unlike any other known animal. Unlike primates that conserve energy by being less active, humans can stay on the move thanks to sweating, which prevents overheating. This metabolic advantage may have been key to our evolutionary success. ...
ve evolved into probably a little bit more professional videos. Although we’re in our early stages here, we’re evolving into being a little bit more of a polished brand and we’re getting a lot of traction now on social media. It was a great start but it wasn’t how I wanted to...
“Gestures may have incubated language until humans evolved the full-blown capacity for it“ The reader is asked to swallow the following unlikely implication of their logic: language didn’t evolve for communication, but rather for internal thought. If language did evolve as a chance mutation, ...
It is a fairly common piece of scientific knowledge that humans evolved from monkeys. However, we only share 93% of ourDNAwith, say, a rhesus monkey. The more precise truth is that humans evolved from chimpanzees, with whom we share 99% of ourDNA. Other than the homogeneity of DNA, sci...
—Human elbows and shoulders evolved as 'brakes' for climbing ape ancestors —Injectable goo could fix joints without surgery, early study suggests —The animal kingdom is full of cheats, and it could be a driving force in evolution We know that the evolution of the knee in humans hasn'...
Humans may have evolved altruistic traits as a result of a cultural "tax" we paid to each other early in our evolution, a new study suggests. The research also changes what we knew about the genetic makeup of our hunter-gatherer ancestors. The origin of
