Is a computer smarter than a human brain?

Computers can be programmed with vast libraries of information, but they can’t experience life the way we do. And in those areas, computers can be smarter than humans. “Today, computers can learn faster than humans, e.g., (IBM’s) Watson can read and remember all the research on cancer, no human could,” says Maital.

Does the human brain evolve?

Human brain size evolved most rapidly during a time of dramatic climate change. Larger, more complex brains enabled early humans of this time period to interact with each other and with their surroundings in new and different ways.

Why were Galen’s wrong?
