The March of Progress (source: http://fooyoh.com)

Google has come up with a doodle today to celebrate the 41st anniversary of a historical find by paleoanthropologists working in Ethiopia—the bones of Lucy, the first female hominid.

Her bones first showed proof how the humans evolved from being apes who lived on trees to the intelligent human species who are tall and walk upright.

She was named ‘Lucy’, inspired by the song Lucy in the Sky with Diamonds by Beatles. The new hominid species made itself known through a few hundred pieces of fossilized bone, which made up a large part of the skeleton. According to carbon dating, they were 3.2 million years old. Skeletons this old were mostly too incomplete or damaged. So, scientists were able to find a lot of information regarding human evolution because the bones were almost intact.


They named the species Australopithecus afarensis.

Lucy’s spine curvature and knee structure were the most important characteristics of her bone structure, which suggested she walked upright– a characteristic attributed to humans.

Lucy stood at 1.1 metres tall and weighed 27 kilograms; this was the adult size for her species. Scientists suggested that her face structure and facial features could be similar to a gorilla. Much like an ape, her skull was small. Compared to her legs, her arms were longer, but not as much as a chimpanzee’s.

She was initially thought to have had a plant-based diet, as suggested to researchers by her cone-shaped rib and the muscular structure of her jaw. But later in 2010, it became known through further findings that the Australopithecus afarensis species cooked, cut and ate meat. They were the first of their kind to take up this process.

The biggest mystery about Lucy’s bones is that her cause of death couldn’t be understood. From studying her teeth degradation, scientists stated that she was a mature, yet young female. So, old age couldn’t have been the cause of her death.

However, on her pubic bone is a tooth mark of a carnivore. Whether it contributed to the cause of death or whether the animal bit her body after her death is not clear.

Lucy’s skeleton is currently quite close to where her bones were discovered. She lies in the National Museum of Ethiopia in Addis Ababa, locked up in a safe, while a plaster replica is on exhibit. She has even toured the United States between 2007 and 2013, even though it was feared that the journey might damage her.

The Google Doodle today is an animation of the famous ‘March of Progress’, an illustration which shows the evolution of man from apes. As a find which showed the key of our evolution today, Lucy has been put in the middle of the evolutionary process in the doodle.

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.
