--- Quote ---New research has revealed the importance of a circadian body clock that matches the rotational speed of the Earth. A team of scientists from Holland, Germany and the UK’s University of Manchester  studied animals in which variation in a single gene dramatically speeds up the natural circadian cycle from 24 to 20 hours. It is the first study to demonstrate of the value of having an internal body clock which beats in tune with the speed of the earth’s rotation.

I've heard that most humans' natural circadian rhythms, especially in modern times, may actually be a bit longer than 24 hours, so that might actually play in Mars's favor. That is, if it can ever be made habitable.
