"The fossil, a thigh bone found in Spain, had previously seemed to many experts to belong to a forerunner of Neanderthals. But its DNA tells a very different story. It most closely resembles DNA from an enigmatic lineage of humans known as Denisovans. Until now, Denisovans were known only from DNA retrieved from 80,000-year-old remains in Siberia, 4,000 miles east of where the new DNA was found.
The mismatch between the anatomical and genetic evidence surprised the scientists, who are now rethinking human evolution over the past few hundred thousand years. It is possible, for example, that there are many extinct human populations that scientists have yet to discover. They might have interbred, swapping DNA. Scientists hope that further studies of extremely ancient human DNA will clarify the mystery."

"The results establish that male brains are optimized for intrahemispheric and female brains for interhemispheric communication. The developmental trajectories of males and females separate at a young age, demonstrating wide differences during adolescence and adulthood. The observations suggest that male brains are structured to facilitate connectivity between perception and coordinated action, whereas female brains are designed to facilitate communication between analytical and intuitive processing modes."

"So, my own proposal - that I wrote up in a paper a couple years ago with a student, Jennifer Chen - was that our universe is like the chicken. There’s a universal chicken. We are not alone. The universe is not a closed system."

"In summary, we have begun to explore an under-appreciated influence on adult behavior—ancestral experience before conception. From a translational perspective, our results allow us to appreciate how the experiences of a parent, before even conceiving offspring, markedly influence both structure and function in the nervous system of subsequent generations. Such a phenomenon may contribute to the etiology and potential intergenerational transmission of risk for neuropsychiatric disorders, such as phobias, anxiety and post-traumatic stress disorder50. To conclude, we interpret these results as highlighting how generations can inherit information about the salience of specific stimuli in ancestral environments so that their behavior and neuroanatomy are altered to allow for appropriate stimulus-specific responses."

"Also use “less” with a number that describes a quantity considered as a single bulk amount: “The police recovered less than $1,500; It happened less than five years ago; The recipe calls for less than two cups of sugar."

"The issue I have is that your definition of “misinformation” is too broad.
“The pretext being fruit flies are similar to human anatomy and it’s okay to ever correlate between the two in an experiment.”
As someone who has spent several years doing invertebrate aging research, this is by far the most common question/issue that arises in talking with just about everyone.
Invertebrates and mammals (i.e. humans) share a great deal of biology in common [sic]. Many significant improvements in human medicine have their roots in invertebrate model organisms (i.e. all modern, non-chemo anticancer drugs have a basis in worm research). Fruit fly anatomy is certainly not similar to human anatomy, but fruit fly physiology is remarkably similar to human physiology. Considering this, the article is hardly “slanting” anything."
