Contrary to the first hypothesis about the increased prevalence of obesity and type two diabetes, humans did not evolve to increase fat storage. More likely, the recent rise in metabolic diseases results from epigenetic factors and the gut microbiome.

A study conducted at the University of Chicago on ant-plant relationships has challenged the theory that organisms in a mutualistic relationship evolve at a slower rate than non-mutualists.
Researchers from Yale University and other institutions, headed by Dr. Victoria McCoy, have unearthed the origins of the Tully Monster, a Carboniferous creature with highly unusual morphology.
Lucy [Falling Through] the Sky with Diamonds: Compressive fractures suggest cause of early hominin’s death
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.
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.
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.
