The slow and steady migration of humans from Africa into Europe was enough to kill off the existing Neanderthal population there, according to a new study in Nature Communications.

Why it matters: "For decades, modern human scientists assumed there must have been something wrong with the Neanderthals — or something right with us — that led to their extinction," the Washington Post reports. But researchers found that although natural selection may have had a role in the survival of modern humans, Neanderthals would have gone extinct regardless. "It's a subtle distinction but it's important," scientist Oren Kolodny told the Post.

The backdrop: For a time, around 50,000 years ago, Neanderthals and humans co-existed in Europe. To figure out why humans survived but Neanderthals went extinct, researchers built a computer model of interactions between populations of the two species. The model showed that, in 12,000 years, the Neanderthal population became extinct, even without added factors of climate change or selective evolutionary advantages in humans.

Justice Department sues Google over alleged search monopoly

The Justice Department and 11 states Tuesday filed an antitrust lawsuit against Google, accusing the company of using anticompetitive tactics to illegally monopolize the online search and search advertising markets.

Why it matters: The long-awaited suit is Washington's first major blow against the tech giants that many on both the right and left argue have grown too large and powerful. Still, this is just step one in what could be a lengthy and messy court battle.

More Floridians cast early ballots for the 2020 election on Monday than in the first day of in-person early voting in 2016, shattering the previous record by over 50,000 votes, Politico reports.

The big picture: Voters have already cast over 31 million ballots in early voting states as of Tuesday, per the U.S. Elections Project database by Michael McDonald, an elections expert at the University of Florida.
