Lucy [Falling Through] the Sky with Diamonds: Compressive fractures suggest cause of early hominin’s death

🕔03:20, 24.Oct 2016

One of the oldest cold cases in history is the death of Lucy, the 3.2-million-year-old hominin. John Kappelman, who completed his undergraduate training at Yale, did some detective work on Lucy’s skeleton; an analysis of her bone fractures revealed that she may have died from falling out of a tree.

A Real-life “Jurassic World”: Recreating Historic Evolutionary Transitions in the Laboratory

🕔02:42, 24.Oct 2016

Rather than speculate on how organisms evolved certain adaptations, scientists are attempting to recreate some of these historic transitions—such as the development of fins into feet—in the lab.

Modern Hunter-Gatherers Reveal Strategies for Adaptive Energy Use

🕔18:51, 10.Nov 2015

The World Health Organization attributes obesity in developed countries to decreases in exercise and energy expenditure relative to our hunter-gatherer ancestors. Where they led active lifestyles, ours are mostly sedentary. In recent research, Yale professor Brian Wood examined total energy

Science or Science Fiction? Uplifting Animals

🕔22:33, 8.May 2015

Uplifting animals, or endowing animals with near-human intelligence, is a concept that has been explored by science fiction writers and movie producers. But real world scientists are interested, too. New research suggests that genetic and neurological modifications could enhance animals’ intelligence.

The Pregnancy Puzzle: Genomic analysis reveals the evolutionary origin of the womb

🕔22:46, 29.Mar 2015

Placental pregnancy is a radical phenotype which arose only once in evolutionary history. Professor Günter Wagner and colleagues have conducted genome-wide analysis on cells from an array of pregnant animals to reveal that ancient transposable elements were the likely vehicles for the origin of this mammalian trait.
