A team of scientists in Chile have said that they found a human footprint that dates back more than 15,000 years, the oldest one ever found in the Americas, the media reported on Tuesday. The discovery challenges the previous timeline and map of human migration into South America.

Most available evidence held that humans did not reach the Patagonia region at the southern tip of South America until 12,000 years ago, Karen Moreno, one of the co-authors of the research, told CNN.


The scientists believe the trace fossil is an impression of the bare right foot of an adult human, Moreno said. The research was published last week in the scientific journal PLOS-ONE.

The footprint was found in 2010 at a paleo-archaeological site in the city of Osorno in the southern part of the country, at the edge of a town home development. But it took years for scientists to confirm the age of the fossil through carbon dating.

A new wave of research has been ongoing on Osorno since 1986 and scientists have uncovered the remains of large animals, ranging from mastodons to horses to a paleo-llama, a larger species of llama that is now extinct.

Tokyo Olympics 2020 Indian wrestler Ravi Kumar enter semi finals.

Indian wrestler Ravi Kumar (57kg) and Deepak Punia (86kg) enjoyed fruitful outings at the Tokyo Olympic Games as they secured semifinal berths in their respective weight categories at the Makuhari Messe on Wednesday.

On the opening day of the wrestling competition, Ravi Kumar defeated Bulgaria's Georgi Vangelov 14-4 on technical superiority to reach the last-four in the men's 57kg category, while compatriot Deepak Punia overcame China's Zushen Lin 6-3 on points to advance to the semifinals.

Ravi Kumar will take on Nurislam Sanayev of Kazakhstan in the last-four, while Punia will be up against David Morris Taylor of the USA.

Earlier, Ravi Kumar had won his opening-round bout by technical superiority against Colombia's Oscar Tigreros to secure a quarterfinal spot. Competing in the Round-of-16 bout against the Colombian wrestler, the 23-year-old Ravi Kumar, who is making his Olympic debut, showed no nerves as he dominated the bout to win by technical superiority (13-2).

Ravi Kumar landed attack after attack and went 13-2 up, winning the bout by technical superiority with minutes to spare. In wrestling, building up a 10-point lead over the opponent results in a victory by technical superiority.

India's 86kg freestyle wrestler Deepak Punia showed no signs of the niggle that had forced him to pull out of the Poland Open Ranking Series in Warsaw in June, as he defeated Nigeria's Ekerekeme Agiomor on technical superiority to secure a quarterfinal berth.

He got his Olympic campaign to a fine start as he was in control from the start of the bout and hardly ever allowed his Nigerian opponent any room to maneuver his moves, finally winning with a 12-1 on technical superiority.

Punia, who had also suffered an elbow injury just before the Games, was slow at the start but came into his own as the bout progressed, inflicting takedowns at regular intervals to earn points.

The Indian wrestler eased into a 4-1 lead at the break and extended his lead comfortably in the second period.

Punia, the silver medallist from the 2019 world wrestling championships, then set up a clash with China's Lin Zushen in the quarterfinals and defeated him 6-3.
