7. New Human Species Biologists all over the world were intrigued upon hearing the 2015 discovery of a new species of human, Homo Naledi, allowing for an ever clearer picture of our ancient ancestry. The findings were unveiled deep in an underground cave in South Africa and is considered one of the greatest collection of human remains ever unearthed. So far, it is known that this species of human grew to an average height of 5 feet and had a brain no larger than an orange. The way the bones in the South African cave were arranged suggests that these human ancestors ritualistically buried their dead, giving scientists a glimpse into our cultural past. 6. Bionic Lens While still in the testing stage, the founder of Ocumetics Technology Corp may have stumbled upon a revolutionary technology that could augment the way humans perceive the world. A new bionic contact lens will give wearers an ability to see the world with stronger than 20/20 vision. Some subjects, who have already tried the lens themselves, claim that they not only see better than ever before but have identified a unique spectrum of colors unfamiliar to the unaided eye. Is this perhaps the first step in the direction of a new era of superhumans? 5. Harder Than Diamond Scientists may have recently discovered a substance harder than diamond, Q-carbon. What gives diamonds their excellent hardness are the chemical bonds that hold them together. The carbon in diamonds is held together by incredibly tight chemical bonds at the microscopic level, giving diamonds their prominent hardness. By the manipulation of carbon atoms, scientists were able to augment their chemical bonds, producing a material that is potentially 60 times harder than diamond. While this substance is still being experimented on, it is a potential prospect for the future of cheap, efficient technologies. 4. First Mammals Researchers from the University of Edinburgh have discovered an ancient species of mammals that survived the notorious extinction of the dinosaurs over 65 million years ago. The reason this find is so significant is that it gives us a glimpse at how mammals began to rule the world previously dominated by their cold-blooded counterparts. The mammal is thought to have been a plant-eater closely resembling a modern beaver. Once the dinosaurs were eliminated these beaver-like creatures began to flourish, given that they were no longer victims of dinosaur predators. Because these little guys were able to withstand the destruction that wrecked havoc on the dinosaurs, an array of mammals, including our ancestors, were finally able to leave their mark on the world.
