Many authors and researchers have speculated about the future evolution of mankind. In 1888 English author H. G. Wells published his famous science-fiction novella The Time Machine featuring a future evolution of humans and is generally regarded as one of the first modern instances of both time travel and speculative evolution.
The failure of the Aerodrome resulted in public ridicule of Langley. Two days after the failed experiment, an editorial published in the New York Times opined: [5] [It] might be assumed that the flying machine which will really fly might be evolved by the combined and continuous efforts of mathematicians and mechanicians in from one million to ten million years...
Birds are one of only four taxonomic groups to have evolved powered flight. A number of animals are capable of aerial locomotion, either by powered flight or by gliding. This trait has appeared by evolution many times, without any single common ancestor. Flight has evolved at least four times in separate animals: insects, pterosaurs, birds, and ...
Humans that leave the familiarity of Earth could morph into a separate species. "These people will become an offshoot of the human tree," Impey said in the interview. "They will probably evolve ...
The adaptation of humans to high altitude is an example of natural selection in action. [2] High-altitude adaptations provide examples of convergent evolution, with adaptations occurring simultaneously on three continents. Tibetan humans and Tibetan domestic dogs share a genetic mutation in EPAS1, but it has not been seen in Andean humans. [3]
Weight is the largest obstacle birds must overcome in order to fly. An animal can more easily attain flight by reducing its absolute weight. Birds evolved from other theropod dinosaurs that had already gone through a phase of size reduction during the Middle Jurassic, combined with rapid evolutionary changes. [3]
Unpowered aircraft are aerial vehicles that can fly without any propulsion mechanism. The ability to fly short or long distances without power has evolved many times in nature. Many creatures capable of sustained wing-powered flight also soar unpowered for much of the time they are airborne.
According to Stephen Hawking, the human race is in danger of being wiped out in the next 100 years, and it's all our own fault. According to the BBC, the physicist says he believes humanity will ...
