A recent study asks why dinosaurs went extinct 66 million years ago while ancient birds still exist today.
The answers look beyond the established assumptions of climate change and the impact of a giant asteroid as the reasons for the end of dinosaurs. Instead, they examine how eggs hatched.
Turns out that it took a much longer time for a baby dinosaur to pop out of an egg, compared to birds. Chickens, in particular, take just three weeks. Which would imply that a calamity might not decimate an entire population waiting to be hatched.
Of course, this may not be the only, or even real, reason for the ubiquitousness of chickens. (And we’re not even talking of theories which track the evolution of the chicken from dinosaurs, with some lack of clarity.)
But the one thing that can be established is that chickens have indeed proliferated across the world as a domestic bird, and the credit goes to humans for taking advantage of the short incubation cycle.
The video above from Sam O’Nella Academy offers a comprehensive – and quick – history of how chickens were domesticated. And it all goes way back to 5,000 BC in South-East Asia, with the red jungle fowl.
But if you’re still wondering which came first – the chicken or the egg – here’s another video that tries to crack the conundrum.
Watch Ruchir's journey: A story that captures the impact of accessible technology
Accessible technology has the potential to change lives.
“Technology can be a great leveller”, affirms Ruchir Falodia, Social Media Manager, TATA CLiQ. Out of the many qualities that define Ruchir as a person, one that stands out is that he is an autodidact – a self-taught coder and lover of technology.
Ruchir’s story is one that humanises technology - it has always played the role of a supportive friend who would look beyond his visual impairment. A top ranker through school and college, Ruchir would scan course books and convert them to a format which could be read out to him (in the absence of e-books for school). He also developed a lot of his work ethos on the philosophy of Open Source software, having contributed to various open source projects. The access provided by Open Source, where users could take a source code, modify it and distribute their own versions of the program, attracted him because of the even footing it gave everyone.
That is why I like being in programming. Nobody cares if you are in a wheelchair. Whatever be your physical disability, you are equal with every other developer. If your code works, good. If it doesn’t, you’ll be told so.
Motivated by the objectivity that technology provided, Ruchir made it his career. Despite having earned degree in computer engineering and an MBA, friends and family feared his visual impairment would prove difficult to overcome in a work setting. But Ruchir, who doesn’t like quotas or the ‘special’ tag he is often labelled with, used technology to prove that differently abled persons can work on an equal footing.
As he delved deeper into the tech space, Ruchir realised that he sought to explore the human side of technology. A fan of Agatha Christie and other crime novels, he wanted to express himself through storytelling and steered his career towards branding and marketing – which he sees as another way to tell stories.
Ruchir, then, migrated to Mumbai for the next phase in his career. It was in the Maximum City that his belief in technology being the great leveller was reinforced. “The city’s infrastructure is a challenging one, Uber helped me navigate the city” says Ruchir. By using the VoiceOver features, Ruchir could call an Uber wherever he was and move around easily. He reached out to Uber to see if together they could spread the message of accessible technology. This partnership resulted in a video that captures the essence of Ruchir’s story: The World in Voices.
It was important for Ruchir to get rid of the sympathetic lens through which others saw him. His story serves as a message of reassurance to other differently abled persons and abolishes some of the fears, doubts and prejudices present in families, friends, employers or colleagues.
