But the small muscles of a bat’s wing are uniquely vulnerable to heat
“Birds of a feather flock together” or rather “opposites attract”? The recently published study on male macaques in Thailand speaks for the former: Behavioral biologists from the German Primate Centre — Leibniz Institute for Primate Research and psychologists from the University of Göttingen have observed that the more similar male Assamese macaques are in their
Human language and communication skills are unique in the animal kingdom. How they developed in the course of evolution is being researched, among other things, using the alarm call system of vervet monkeys. East African vervet monkeys warn their conspecifics against predators with special alarm calls that mean “leopard,” “eagle” or “snake.” In a recently
Crops such as wheat and maize have undergone a breeding process lasting thousands of years, in the course of which humankind has gradually modified the properties of the wild plants in order to adapt them to his needs. One motive was, and still is, higher yields. One “side effect” of this breeding has been a
