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

Evolution as we know it is driven by mutations in genes. But researchers at Yale were curious about what surrounds a gene. That is, how does a whole gene network evolve?
New Yale research reveals how Salmonella bacteria move when flagella are of no use, adding dimensions to our understanding of bacterial choreography.
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.
Through both observational and genetic methods, Teresa Feo in the department of ecology and evolutionary biology has determined that two populations of Bahama hummingbirds, previously believed to belong to the same species, are actually two distinct species.
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.
Genomic analysis of finch species from the Galapagos archipelago and Cocos islands reveals a genetic basis for the beak diversity studied by the father of evolution.
Turning over is neither easy nor trivial for a belly-up tortoise — lying flipped over on its shell makes the reptile vulnerable to predation, among other hazards. According to a new study conducted at the University of Belgrade, certain types of tortoises may have an advantage in this situation depending on the geometry and size of their shells. In addition, researchers have investigated the evolutionary trade-offs of these ideal shell shapes.
Recently, a team of 146 scientists unraveled the genome of the tsetse fly, the vector of a lethal disease called sleeping sickness. With this new genetic information, many scientists have proposed innovative solutions to protect the 70 million people in sub-Saharan Africa who are affected by this disease.
A Yale-led group discovers and characterizes an ancient carnivorous crustaceous using high-tech methods.
