The evolution of justice

Chimpanzees, our closest relatives, turn a blind eye to crimes that don’t affect them directly, suggesting that third-party punishment— the foundation of complex societies governed by laws s and courts—is a uniquely human development. German researchers trained chimpanzees to 1 play one of three roles while facing one another in cages: One was given access to food within reach of […]

Antarctic Fish Have Ice In Their Veins

Scientists have revealed that some fish that thrive in the freezing cold waters of the Antarctic actually have ice in their veins. A protein in their system called notothenioids not only keep the fish from freezing to death, but also keeps ice crystals in their veins. Although the ice crystals would melt at temperatures just slightly above freezing, the fish […]

Chimps: Natural-born killers

Why do chimpanzees kill one another? For years, many studies have shown that chimps that were observed killing one another had become more aggressive only when humans encroached on their environment. But new studies have lent weight to an alternative theory: Chimpanzees are, like humans, natural-born killers who use violence as a means of expanding their territory and increasing their […]

The evolutionary roots of monogamy

The evolutionary roots of monogamy

As an evolutionary strategy, the evolutionary roots of monogamy have long puzzled scientists: When a male pairs off for life with one female, he limits how many offspring he can produce, thus reducing his chances to pass on his genes. Few species are monogamous, yet 5 percent of mammal species are, including wolves and beavers—and about a quarter of primates. […]

Ancient fossil forest unearthed in Arctic Norway

UK researchers have unearthed ancient fossil forests, thought to be partly responsible for one of the most dramatic shifts in Earth’s climate in the past 400 million years. The fossil forests, with tree stumps preserved in place, were found in Svalbard, a Norwegian archipelago situated in the Arctic Ocean. They were identified and described by Dr Chris Berry of Cardiff […]
