Wildlife researcher Evon Hekkala, Ph.D., from the American Museum of Natural History and, found herself in Egypt with a crocodile mummy in her hand. That’s when she discovered that there were two species of crocodiles that inhabit the Nile River instead of only one, as scientists previously assumed.

While modern researchers were surprised to learn this, Hekkala, who is also an assistant professor at the University of Fordham, believes that ancient Egyptians living thousands of years ago were able to tell these crocs apart. They kept them around, like some kind of scaly cat species, and mummified them as a symbol of Sobek, or Suchos — the father of the moon in Egyptian cosmology.

“I love that the cosmology of different cultures sometimes can lead us to hypotheses that we never would have realized,” Hekkala told Inverse on Wednesday, where she presented her findings at the Inverse Lunar Eclipse Party and Science Fair at Caveat in New York City.

“So [the Egyptians] had a hypothesis that this was a separate species 2,000 years ago and they identified these as separate species of crocodiles that they kept in temples. Two thousand years later, we use DNA and show that they were absolutely right,” she says. Hekkala first published her findings in the journal Molecular Ecology in 2011.

This newly discovered species was named Crocodylus suchus after the god Sobek, who was also the god of fertility. In ancient Egypt, royalty and commoners alike would be buried with mummified Crocodylus suchus because it was believed to grant them fertility in the next life.

“Everybody would have crocodile mummies because they were thought to grant strength in crossing the rivers into afterlife and fertility because they wanted to make sure they were fruitful even in the afterlife,” said Hekkala.

Sobek was so damn fertile that he got together with Hathor, the queen of the Milky Way, to give birth to Khonsu, the god of the moon. In essence, a croc had sex with a queen to make the moon — if only science were that easy.

SpaceX is gearing up to send humans into space for the first time. On Monday, CEO Elon Musk confirmed a report that claimed NASA estimates the firm will be ready for people-carrying space adventures as early as April of next year. While a good sign for the company’s Mars mission, a successful human test flight would also enable a new method of sending people to the International Space Station.

When you imagine an Egyptian mummy, you probably picture the embalmed body of a pharaoh, carefully wound in long strips of linen and laid in an ornate sarcophagus. But the mummies of an earlier age weren’t laid to rest in such decadence, suggesting to the scientists who found their bodies in shallow pits that they were preserved by chance, sand, and air. This “natural preservation” theory, however, might be laid to rest by a study published Thursday in the Journal of Archeological Science. Prehistoric Egyptian mummies, the authors say, were also treated with care.

In modern society, you can be lazy and not face much consequence. Don’t want to cook? Order Seamless. Don’t want to move? Call a Lyft. But according to a controversial new study, the same could not be said for Homo erectus, an ancient relative of our species. In the study, scientists claim that H. erectus went extinct because it existed in a constant state of meh.

During their 3,000-year dominance over Mesoamerica, the Mayans built elaborate architectural structures and developed a sophisticated, technologically progressive society. But immediately after reaching the peak of its powers over the entire Yucatan Peninsula, the Mayan Empire collapsed, falling apart in just 150 years. The reasons for its sudden demise remain a mystery, but in a new Science study, scientists find clues buried deep in the mud of Lake Chichancanab.

In recent years, we’ve learned that sea level rise will put coastal cities at risk of greater flooding due to storm surges and at risk of flooding without storms. But new research suggests that sea level rise could also increase the danger of tsunami hazards in those cities, even if they were typically immune from the catastrophic waves in the past. One of these cities is Macau, the Las Vegas of Asia, which stands to lose its world-renowned luxury hotels and casinos if climate change continues at its current pace.
