DEGENERATION

"Evolutionary theorist Oliver Curry of The London School of Economics expects a genetic upper class and a dim-witted underclass to emerge.
The human race would peak in the year 3000, he said - before a decline due to dependence on technology. Spoiled by gadgets designed to meet their every need, they could come to resemble domesticated animals.
... The descendants of the genetic upper class would be tall, slim, healthy, attractive, intelligent, and creative and a far cry from the "underclass" humans who would have evolved into dim-witted, ugly, squat goblin-like creatures.
... Social skills, such as communicating and interacting with others, could be lost, along with emotions such as love, sympathy, trust and respect. People would become less able to care for others, or perform in teams."
