Humans developed a tolerance to milk 10,000 years ago, but other signs of evolution have happened more recently. In the past 150 years, the average height has gone up 10 centimeters, and in the past 65 years, the average lifespan has increased by 20 years. These are pretty impressive feats, and the human race doesn't show signs of stopping when it comes to change.

With that in mind, ASAPScience takes a look at what the human race might look like in the next 1000 years. One theory, transhumanism, suggests that we will blend biology and machine to become advanced beings. Other predictions include humans getting even taller and most languages disappearing. If these possibilities seem extreme now, just think about how much we've grown—physically and technologically—over the past century and a half.
