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...
tears have received little serious attention from scientists. Here, we summarize recent theoretical developments and research findings. The evolutionary approach offers a solid ground for the analysis of the functions of tears. This is especially the case for infant crying, which we address in the f...
To approach a question 400 million years in the making, researchers turned to mudskippers, blinking fish that live partially out of water.
Dr. looking to help students succeed and progress their education See tutors like this I would argue that our feet have not evolved to be tender, but it is the practice of wearing shoes and avoiding natural surfaces that has caused this. There are still millions of people in the world w...
Furthermore, the researchers uncovered that the egg employs an innate immune pathway to dismantle paternal mitochondria, treating them as intrusive entities. This aligns with the hypothesis that mitochondria, originally bacterial invaders, co-evolved with host cells to offer mutual benefits. ...
are not “women,” for they were born with the reproductive apparatus that evolved to produce eggs. As for chromosomes, having two X chromosomes gives you a very high probability of being a woman, but a rearrangement of genetic information can decouple chromosome constitution from the gametic ap...
"We are the only paper that has ever put together a plausible scenario for how it happened," Yanai told Live Science. "We're now walking on two feet. And we evolved a big brain and wield technology," he said. "All from just a selfish element jumping into the intron of a gene. ...
So why has sex evolved in so many species? Surprisingly, there's no single clear answer to this question. Indeed, to date, researchers have developed more than20 different hypotheses. Lately, a number of experiments have started testing these theories, taking us closer to finding a solution. ...
Human beings did not evolve frommodern-daymonkeys; human beings and modern-day monkeys both evolved from an extinct common ancestor (which was also, colloquially speaking, ‘a monkey’). In the huge evolutionary family-tree of all the species that have ever lived on earth, humans and modern-...
“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, ...
