The pendular running gait described in this article as one of the most efficient bipedal gaits looks remarkably like the way eyewitnesses claim Bigfoot creatures move. In a Bigfoot hoax, one might use a gait that is unhuman but energy efficient, as the costume would be rather heavy. On the other hand, since such a […]

Perchance to Hibernate
As scientists work to unravel the secrets of mammalian hibernation, they're eyeing medical applications that could aid wounded soldiers, stroke victims, and transplant recipients, among others.

Monkey see, monkey smell That monkeys get “weirded out” by seeing themselves in mirrors doesn’t seem unexpected (“Reflections of Primate Minds: Mirror images strike monkeys as special,” SN: 7/23/05, p. 53). Were a familiar or an unfamiliar same-sex capuchin seen, the test subject would be bombarded not just by visual images but also by smells […]

Big leap The pendular running gait described in “Stepping Lightly: New view of how human gaits conserve energy” (SN: 9/17/05, p. 182) as one of the most efficient bipedal gaits looks remarkably like the way eyewitnesses claim Bigfoot creatures move. In a Bigfoot hoax, one might use a gait that is unhuman but energy efficient, […]

Rascal rabbits Evidence of animals sensing where people are looking and what they’re seeing is interesting yet hardly new (“Monkey See, Monkey Think: Grape thefts instigate debate on primate’s mind,” SN: 3/12/05, p. 163). For years, I have observed that wild rabbits will remain motionless as long as I stare in their direction. But as […]

Chimps to People: Apes show contrasts in genetic makeup
The first comparison of the chimpanzee genome to that of people has revealed new DNA disparities between ourselves and the primate species most closely related to us.

Infectious Evolution: Ancient virus hit apes, not our ancestors, in the genes
A potentially deadly infection wormed its way into the DNA of ancestral chimpanzees and gorillas between 4 million and 3 million years ago, thus altering the evolution of these African apes while keeping clear of human ancestors on that same continent.

Seminal Discovery: Promiscuous females speed sperm evolution
A gene responsible for semen viscosity has evolved more rapidly in primate species with promiscuous females than in monogamous species.

More junk makes for better dads
A new analysis links dutiful fatherhood in prairie voles to a stretch of DNA once dismissed as meaningless.
