Human evolution has a public relations problem. That isnt just because some people are skeptical of science in general or because creationists reject the notion of evolution. As it is often studied and taught, human evolution can be male-biased and Eurocentric, even reeking of sexism and racism.

This evolutionary tale from PresidentTrump, with help from a ghostwriter, in Think BIG and Kick Ass in Business and Life, illustrates the problem:

The women I have dated over the years could have any man they want; they are the top models and the most beautiful women in the world. I have been able to date (screw) them all because I have something that many men do not have. I don't know what it is but women have always liked it. So guys, be cocky, confident, smart, and humorous and you will be able to get all the women you want. We may live in houses in the suburbs but our minds and emotions are still only a short step out of the jungle. In primitive times, women clung to the strongest males for protection. They did not take any chances with a nobody, low-status male who did not have the means to house them, protect them, and feed them and their offspring. High-status males displayed their prowess through their kick-ass attitudes. They did not give a crap about what other people in the tribe thought. That kind of attitude was and still is associated with the kind of men women find attractive. It may not be politically correct to say but who cares. It is common sense and it's true and always will be.

This just-so story about men, women, sex and success may fit with many peoples impression of human evolution, but it contradicts the actual science.

First, simple genetic explanations dont exist for most complex behaviors. There are no known genes for kick-ass attitudes or wanting to have sex withsomeone who exhibits them. Further, its unlikely that Trump would exist had his ancestors not given a crap about what other people in the tribe thought. Prosociality cooperating with others, maintaining rich and mutually trustworthy relationships is humanitys bread and butter. Finally, althoughits true that we are primates descended from a long line of jungle-dwelling ancestors before they expanded into all kinds of habitats, its also true that evolution never stopped. Very little about us always will be.

Yet for all the missed beats and flat notes, its clear that Trumps tale is riffing on some outdated but persistent ideas in popular science.

[How to teach kids about climate change where most parents are skeptics]

In every human population around the world, men are on average larger and stronger than women, as is the case in most other primate species. This is often explained by sexual selection for male dominance, that is, male vs. male competition for mates. So, in the past, bigger, dominant males fought and scared away smaller ones and had more opportunities to mate with females. As a result of their relatively greater reproductive output, the genes of these males got passed on at a relatively higher rate than the genes of the smaller guys. This process was enhanced by female preference for making babies with these bigger, stronger, dominant males.

Traditional perspectives on human evolution such asthis one about men and womens body size and behavior have long dominated the science and its popular dissemination. But it deserves scrutiny.

Presenting a human evolutionary narrative over and over againin whichmale competition and female preference are the explanation for big, strong males is too narrow, too simple. It reminds me of when students claim that their B in my human evolution course is keeping them off the deans list, but their transcript isnt exactly straight As. Theres usually more to a story.

A more nuanced explanation for male dominance is less likely to lead anyone to conclude that patriarchy is hard-wired in our genes. Just look more carefully at nature, at the social sciences, the humanities, art, literature! Myriad biological and non-biological factors contribute to the development and persistence of the global phenomenon of how men are disproportionately powerful, and even more so if they belong to the ruling race, religion or clan.

Male baboons and chimpanzees coerce and harass females for sex and obviously male humans do, too, but thats not evidence for genetically hard-wired, male-dominant sexual behavior at all, let alone for it being at the root of the patriarchy. Imagine someone leaping from the observation that primates eat hand-to-mouth to the assumption that its a genetic cause of our growing waistlines. When it comes to sex, we can inadvertently make some atrocious leaps of evolutionary logic about any species, but most of all ourselves. Not only are all primates stellar social learners of good, bad and nifty behaviors, but this overly imaginative primate cant help but inject bias into making sense of it all. Shared behaviors of monkeys, apes and us are not excuses to be fatalistic about sexual harassment and assault by humans who have a much more complex culture in which to learn cooperative behavior and to enforce it. Yes, were primates, and were also humans.

It may be true that Trumps version of maleness is a result of natural and sexual selection, but every other version of maleness across the globe is just as much (or just as little) a product of evolution as is his. If we ask different questions, we reveal other facets of our evolutionary history.

[Humans are driving the evolution of new species]

Primatologist Sarah Hrdy in 1981 published one of many books toward a more complex and complete human evolutionary history called The Woman That Never Evolved. Using the same theoretical tools that scientists had used to build the male-driven explanation for male body size and male dominance, she flipped the question. She asked why so many females in the primate world werent as big as males or even bigger, since female primates compete, too.

Females do not coyly wait for a champion to earn the honor of having sex with them. They do not necessarily cling to males for defense any more than males do, and often such clinging is just a warped description of male dominance over smaller females. Only some of the facts of nonhuman primate behavior are gathered, even fewer are published, and when they are, human bias factors into their interpretation. What we have is only part of the story.

Evolutionary theory has grown up since its conception. Based on mountains of observations of genes and traits over generations, evolutionary scientists have developed much more skepticism toward explanations that lean too dogmatically onnatural or sexual selection. Scientists increasingly resist the temptation to assume that everything evolved for asingle or specificreason, and that everything must exist because it boosted the survival and reproduction of those who passed it on. We know that perpetual mutation and the chance of passing along (or not passing along) traits occurs within complex cooperative systems with constant biological change.

The biological changes that matter most often have to do with embryological development rather than beating the competition to food, safety, or mates.We know that natural and sexual selection permit constant change,are usually very weak, and tolerate a lot of variation. This view of life is household thinking for many scientists and scholars, but it has hardly made its way out to the public. Why not?

We seem to be stuck on an old story thatis less than what we deserve. Maybe its because some analyses trying to break the male-biased mold are dismissed as feminism, which is still widely assumed to be incompatible with the scientific pursuit of knowledge. Maybe its a thirst for American narratives where exceptional individuals are being specially selected. Maybe its because when a persons autobiography is largely a quest to get laid, their biography for our species cant help but echo that.

[Is the eclipse moving bacward?]

But there are billions of human experiences, all equally worthy of influencing evolutionary thinking.

Like most girls, I reached my maximum height years before my male friends did. What I have learned as a biological anthropologist suggests that physiological constraints on growth could help explain why women stop getting taller right around the time we start regular menstrual cycles, a costly metabolic process that could divert resources away from height. Pregnancy and lactation are even costlier, so womens smaller bodies may boost but also betray their talent for metabolic marathons. There could be a similar explanation for why men do not grow even bigger than they do, as we might expect after generations of kick-ass attitudes. Furthermore, male dominance may be much more the result of their bigger bodies than the cause. Anthropologist Ruth Benedict summed it up long ago by writing, The trouble with life isn't that there is no answer,it's that there are so many answers.

Human evolution is for everyone, Trump included. We each take our species origin story personally. Evolution may as well be a gigantic Rorschach test, and that goes for the scientists, too. Some see the competition and identify with its battle cry survival of the fittest, while others see infinite cooperation despite constant change. Perspectives on evolution vary wildly among experts and nonexperts alike, but too few are aware of it. So lets flood the texts, the classrooms, the campfire circles, the zeitgeist with diverse stories from diverse perspectives on the science of human evolution.

Without diverse lives contributing to the science, our evolutionary stories will remain simplistic and woefully incomplete. And when translated in the public sphere, our myopic stories are too often used to justify self-interest and the status quo, such asgender inequality and racism. Trump made this too garish to ignore any longer.

Science has a diversity problem. There was passionate debate before the March for Science about whether it should be explicitly political and whether it should include diversity and inclusion among its chief causes. Beyond the many impacts of these issues on human lives, there are also very real consequences for the knowledge that humans create. Diversifying the brains, bodies and voices of science means better science, better understanding of how the world works. Perhaps they will generate questions about human evolution that no one thought to ask.

A necropsy completed on a beartrapped and killed near Wardin the wake of last weekends attack on a teenager at a camp area showed human DNA on its claws, wildlife officials said Friday.

The results boost Colorado Parks and Wildlife staffs confidence they killed the right bear, according to area wildlife manager Larry Rogstad.

A 280-pound male black bearattacked a 19-year-old staff member at Glacier View Ranch near Ward at about 4 a.m. Sunday as he was sleeping, biting his head and attempting to drag him away. The young man, with the help of other staff members, was able to fight off the animal.

The necropsy was performed by Colorado Parks and Wildlife pathologist Karen Fox. Rogstad had few other details immediately available on the necropsy results.

However, he added, She did an immediate inspection for rabies, and it was negative for rabies.

Natalia Veselnitskaya, the Russian lawyer who attended the June 9, 2016, meeting at Trump Tower with Donald Trump Jr., has for years beenworking to overturn the Magnitsky Act, a 2012 U.S. law that barred Russian officials suspected of human rights abuses.

Russian AmericanRinat Akhmetshin confirmed to The Washington Post on Friday that he also attended that meeting. He, too, has lobbied against the Magnitsky Act.

So what is the Magnitsky Act, and why is it the focus of so many powerful Russian interests?

The origin

The law is named after Sergei Magnitsky, a Russian lawyer and auditor who in 2008 untangled a dense web of tax fraud and graft involving 23 companies and a total of $230 million linked to the Kremlin and individuals close to the government. Magnitsky was the target of investigations, arrested by authorities and kept in jail without charges. He was beaten and later died under mysterious circumstancesin jail just days before his possible release.

Independent investigators foundinhuman detention conditions, the isolation from his family, the lack of regular access to his lawyers and the intentional refusal to provide adequate medical assistance resulted in the deliberate infliction of severe pain and suffering, and ultimately his death.

Thelaw

The Magnitsky Act was signed by President Barack Obama in December 2012 as a retaliation against the human rights abuses suffered by Magnitsky. Thelawat first blocked 18 Russian government officials and businessmen from entering the United States, froze any assets held by U.S. banks and bannedtheir future use ofU.S. banking systems. The act was expanded in 2016, and now sanctions apply to 44 suspected human rights abusers worldwide.

Its official title is a mouthful the Russia and Moldova Jackson-Vanik Repeal and Sergei Magnitsky Rule of Law Accountability Act of 2012. In most news stories and accounts, the shorthand is simply the Magnitsky Act.

Bill Browder, an American hedge fund manager who hired Magnitsky for the corruption investigation that eventually led to his death, was a central figure in the bill's passage.

How does adoption factor in?

When pressed on the details of his meeting with a Kremlin-connected lawyer at Trump Tower in June 2016, Donald Trump Jr. appeared to downplay its significance by linking it to concerns over an issue that appears uncontroversial on its surface: adoption. But the barring of U.S. adoptions of Russian children is a flash point of tense diplomatic relations and tied directly to the Magnitsky Act.

Two weeks after Obama signed the Magnitsky Act, Russian President Vladimir Putin signed a bill thatblocked adoption of Russian children by parents in the United States. Russia thenalso imposed sanctions on Browder and found Magnitsky posthumously guilty of crimes.

Supporters of the bill at the time cited mistreatment of Russian children by adoptive U.S. parents as the reason for its passage. But it was widely viewed as a retaliatory act, and the issues have been linked since.

Trump Jr. said that despite assurances that Veselnitskaya would come bearing incriminating information about Hillary Clinton in their 2016meeting, the topic quickly shifted to the Magnitsky Act and U.S. adoptions from Russia.

Browder described Veselnitskaya in an NPR interview as a longtime foil to him in her effortsto repeal the Magnitsky Act. She represents a member of the Katsyv family, whose company is under investigation by the Justice Department in connection with the laundering of real estate money in New York.Denis Katsyv has lobbied to overturn Magnitsky and to end Russia's American adoption ban.
