A female crocodile from a zoo in Costa Rica was able to impregnate herself in what scientists are now calling the first-known case of a “virgin birth” for the species.

The crocodile, who has apparently not had contact with a male crocodile in nearly 16 years, was able to produce an egg containing a fetus that was 99.9 per cent genetically identical to herself.

Details about the crocodile’s virgin birth, also called facultative parthenogenesis, were published in the scientific journal Biology Letters on Wednesday.

Researchers wrote the crocodile, which lives in captivity in Parque Reptilania, may have inherited the ability for asexual reproduction from an evolutionary ancestor.

Chris Hemsworth Clarifies His Comments About Stepping Back From Acting Due to Health Concerns (Exclusive)
Chris Hemsworth is getting ready to celebrate his 40th birthday this summer, but he's not even close to slowing down!When the actor and his director, Sam Hargrave, sat down with ET's Rachel Smith to promote their thrilling Netflix sequel this week, Hemsworth was quick to clarify comments that got «sort of blown out of proportion» about him taking a step back from acting.Last fall, the  star told   that he planned to take some time off after promoting his unscripted Disney+ adventure series,. The decision, he said at the time, coincided with an episode of the show on death, as well as one in which Hemsworth agreed to take a genetic test, which ultimately revealed that his risk of developing Alzheimer's is eight to 10 times higher than that of the general population — due to the fact that Hemsworth has two copies of APOE4 (the apolipoprotein E gene), one from his mom and one from his dad. After learning the results on the show, Hemsworth said in a confessional that «the idea that I won't be able to remember the life I've experienced, or my wife, my kids, is probably my biggest fear.»However, Hemsworth said, the decision to take a brief career break was not as connected to the genetic test as it may have seemed.«It all got a little sort of blown out of proportion,» he shared.

PHILADELPHIA - Just days after a tanker carrying thousands of gallons of gasoline crashed under near I-95, causing part of an overpass to collapse, city leaders and officials are set to announce the timeline for repairs as part of a reconstruction plan. On Sunday, a tanker truck with 8,500 gallons of gasoline was traveling in the northbound lanes when it overturned on the curve of an off-ramp, officials say. The crash caused gasoline to leak into the roadway and sparked a large fire under I-95 at Cottman Avenue, causing it to collapse into the roadway underneath it. Newly obtained surveillance video captured the moment a tanker truck carrying 8,500 gallons of gasoline crashed and caught fire underneath I-95 in Northeast Philadelphia. The resulting fire caused a portion of the roadway to collapse.The collapse left the tanker operator, 53-year-old Nathaniel Moody, whose family says he was an experienced driver with more than 10 years of experience, dead. RELATED: I-95 collapse: Truck driver involved in tanker crash identified by familyIt also left the northbound and southbound lanes of I-95 closed between the Woodhaven Road and Aramingo Avenue exits. The damage has caused delays and traffic nightmares for commuters in Philadelphia, the Delaware Valley, and across the northeast. In a Tuesday press conference, U.S.
