Don't listen to what Charles Darwin says — "survival of the fittest" might be old news.

Researchers at the University of Kansas have theorized that species that use more energy on a daily basis are actually more likely to go extinct, compared to ones that use less. Their study, published in the journal Proceedings of the Royal Society B, analyzed more than 300 million species of mollusk in order to determine that species with a high metabolism were at a higher risk of going extinct than low-metabolism species.

Why mollusks? Simply because there are so many of them, CNN explained. The "sheer magnitude of data" made them a good choice to study the differences in metabolism and extinction rates.

The study's findings suggest that being "lassitudinous and sluggish" might just be the best way to ensure the long-term survival of your species, said Bruce Lieberman, the study's co-author. Using less energy to function might mean that you can survive more easily in periods when getting food, or other sources of energy, isn't easy.

However, researchers were quick to note that this might not be the best strategy for us humans — so don't quit your workout routine just yet. "You can't just decide to be lazy as an individual and expect to live longer," said Luke Strotz, the study's lead author. It's not your personal choices, but rather the tendencies of your species as a whole, that make a difference to evolution.

Although these findings are only being applied to marine life as of now, they may be able to eventually help us understand why other "lazy" species, like sloths or pandas, are still around today. Read more about this study at CNN. Shivani Ishwar

Kansas Gov. Jeff Colyer (R) is among many who have called for the resignation of a local official, Leavenworth County Commissioner Louis Klemp, for a remark in which he used the phrase "master race," a concept from Nazism.

Klemp, who is white, told consultant Triveece Penelton, who is black, they were together "part of the master race" because they both have a gap in their teeth. "I don't want you to think I'm picking on you, because we're part of the master race," Klemp said. "You know you've got a gap in your teeth. You're the master race. Don't ever forget that."

Klemp has defended the comment as a joke, and another Leavenworth County official said Klemp has repeatedly used the phrase about gapped teeth in the past. However, Leavenworth's mayor said Klemp has been more inappropriate at other public occasions and this remark demonstrates a lack of "common decency."

"Racial and discriminative language have no place in our society,' Colyer said Saturday, "and most especially when spoken by someone holding public office." Bonnie Kristian

One person was accidentally killed and more than 200 injured in large-scale protests against higher fuel taxes in France on Saturday.

An estimated 250,000 people, many wearing yellow safety vests, turned out in about 2,000 locations around the country to block roads and highways. The new tax was supported by French President Emmanuel Macron, and demonstrators called for his resignation. Macron's approval rating was at a dismal 21 percent as of October.

"We are not political people; we do not belong to a union; we are citizens," said one protester near Paris, Didier Lacombe. "The taxes are rising on everything. They put taxes on top of taxes. It is not the tax on gas; it's everything. The injustice is greater and greater."

"The price of fuel is as politically and sociologically sensitive as the price of wheat in the ancient regime," French public opinion researcher Jerome Fourquet told The New York Times. High wheat prices were among the factors leading to the French Revolution. Bonnie Kristian

Steve Carrell hosted Saturday Night Live for the third time, and after much teasing over whether he'd ever reboot The Office, he got down to the business of the evening: mocking President Trump in character as Amazon's Jeff Bezos.

"As you know, Amazon just announced the location of its two new headquarters in New York and Virginia, and everyone — except for the people who live there and the people who live in all the places we didn't choose — is thrilled," Carrell as Bezos begins.

He quickly shifted to address the rumors head on: Did he choose these locations, one where Trump grew up and one close to the White House, to overshadow the president? "That's simply not true," SNL's Bezos says. "I chose our locations because they were ideal for growing business, not just to make Donald Trump think about how I'm literally 100 times richer than he is."

And the new locations aren't Amazon's only exciting news, Bezos notes. The company is also debuting delivery drones humanized by suspiciously Trumpian wigs, as well as Amazon Caravan, a special new delivery service exclusive to Trump properties. Watch the full sketch below. Bonnie Kristian

President Trump on Saturday downplayed Friday's report that the CIA has concluded Saudi Crown Prince Mohammed bin Salman ordered the murder of U.S.-based Saudi journalist Jamal Khashoggi at the Saudi consulate in Istanbul.

"They haven't assessed anything yet. It's too early. That was a very premature report," Trump told reporters. "We'll be having a very full report over the next two days, probably Monday or Tuesday," he said, adding that it will include "who did it."

The president also praised Saudi Arabia as "a truly spectacular ally in terms of jobs and economic development." He has repeatedly resisted calls to end U.S. arms sales to Riyadh over Khashoggi's death and the Saudi military intervention in Yemen's civil war, claiming the economic toll on the United States would be too high.

Vice President Mike Pence took a harsh line on China at the Asia-Pacific Economic Cooperation (APEC) Summit in Papua New Guinea on Saturday, pledging Washington "will not change course" on trade policy "until China changes its ways."

"We have great respect for [Chinese President Xi Jinping] and China," Pence said, "but as we all know, China has taken advantage of the United States for many, many years, and those days are over." He accused Beijing of unfair trade and lending practices and suggested additional tariffs may be on the way.

President Xi also spoke, arguing, "Unilateralism and protectionism will not solve problems but add uncertainty to the world economy." He called for further cooperation on trade and infrastructure development, defending his signature Belt-and-Road Initiative against Pence's critique. "History has shown that confrontation, whether in the form of a cold war, a hot war, or a trade war, produces no winners," Xi said. Bonnie Kristian

President Trump flew to California on Saturday to survey and discuss the massive fires still raging throughout the state. But one very, very important topic didn't come up.

While flying back to Washington Saturday night, Trump told reporters he and Governor-elect Gavin Newsom (D) didn't talk about climate change — a factor that's likely made the deadly fires far worse than expected. "We have different views but maybe not as different as people think," Trump said of his visit with Newsom, presumably because the two didn't discuss a reality that Trump doesn't quite believe in.

California is at highest risk of wildfires during the summer. But this year's fire season started earlier than usual, per The Sacramento Bee, and the worst of it came after the season typically ends with November's Camp and Woolsey fires. The Camp Fire has left 71 dead and burned 148,000 acres as of Saturday morning, per the California Department of Forestry and Fire Protection. The Woolsey Fire is now 82 percent contained, but still left 3 dead and 98,362 acres ravaged, Cal Fire reports. And California's increasingly dry climate, made even worse by climate change, is likely to blame.

Trump conceded in a Friday interview with Fox News' Chris Wallace that climate change "contributes maybe a little bit" to harsher wildfires, but went on to say "management" and a lack of raking dry leaves were mostly to blame. After visiting an entire town destroyed by the Camp Fire on Saturday, Trump told reporters nothing changed his mind.
