More questionable science abounds in a recent article ["Female Mammals Follow Their Noses to the Right Mates"] regarding mammal mating habits.  Although the original paper was published in 2009, it hasn't improved with age.

One of the more telling problems occurs with the following quote:

Since the dominant males often chase away other males, it's hard to tell if females are choosing to mate with certain males, or are merely mating with them by default.

I recently watched the full two hours of this presentation [Evacuate Earth] and was disappointed in the fact that speculation rapidly degenerated into silliness, and ultimately pseudoscientific nonsense.

A recent article entitled "Fluctuating Environment May Have Driven Human Evolution", proceeded to take something that is obvious and attempt to create even more significance from it.  It is obvious, that environmental changes [yes, including fluctuations] have driven ALL of evolution, so to even qualify it as "human" indicates some attempt to make the results more significant than they are.

However, the intent of this article in trying to assign relevance was exemplified by this quote:

According to Magill, many anthropologists believe that variability of experience can trigger cognitive development.

A recent article pointed out a radical conclusion published in the British Medical Journal that reducing dietary fat intake could lead to weight loss and reduced BMI.

Obviously such radical results will need to be verified and peer-reviewed, but it is expected that additional studies will show that increased sleep will make you feel less tired.  Exercise will tend to promote fitness, and eating will make you feel less hungry.

Ain't science grand!
