From Listenwise -- Migration has been a huge part of human history. Experts agree that early humans started out in Africa and began to migrate out of Africa to different parts of Europe and Asia around 100,000 years ago. This migration occurred in waves but we don’t know why early humans left Africa. Recent research supports the theory that climate change may have been the force that drove early humans out.
From Listenwise -- The earliest known fossil that lead to humans was recently discovered in Ethiopia. Scientists have uncovered a lower jaw with five teeth. The jaw is estimated at about 2.8 million years old, and is nearly half a million years older than the previous record for a human-related fossil. This bone could help explain a branch in the human family tree. Listen to the story to find out how this fossil could fill a gap in the history of human evolution.
From Listenwise, September 22, 2016 -- Sharks can live to be over two hundred years old, and recently a Greenland shark was found who may have lived up to 512 years. These sharks are the longest living vertebrates known to exist. They can be found swimming in the Arctic seas, where researchers are spending time studying the old creatures. Listen to the story to hear more about this fascinating species.
From Listenwise -- Woolly mammoths were large, elephant-like creatures that lived tens of thousands of years ago, during the last great ice age. The thick, furry coat is one of several traits that gave woolly mammoths an advantage in a very cold environment. Today, the closest biological relative is the Asian elephant, which prefers warmer climates. Scientists were curious about the genetic variations between the woolly mammoth and the Asian elephant and what might account for the differences between the two species.
From Listenwise, September 2, 2016 -- New Delhi, India has some of the the most polluted air in the world. Levels of pollution reached hazardous levels many days of the year. For the people of New Delhi, this has meant an increase in health problems such as asthma and other sicknesses. As India’s growth continues, it consumes more energy, which creates pollution. This story illustrates the balance between economic growth and the health threats of pollution produced by all this growth.
From Listenwise, August 24, 2016 -- For the first time in history, two pilots flew the Solar Impulse 2, a solar powered plane, around the world without using any fuel. This technology will have to be developed more before the public will be able to fly in them. Nevertheless, this flight symbolized the innovative progress made by aviators and energy conservationists. Listen to the story to hear more about the flight from pilot, Bertrand Piccard.
