Even in a world of absolute equals, small strokes of luck can shape survival and evolutionary success in nature.

According to a recent study by Matthew Zipple, an evolutionary biologist at Cornell University, luck could be an important ...

A new study on mice shows that luck in early life can determine success as an adult, especially when competition is high.

For example, Zipple said, discovering a shelter early in life might be a small win for a male mouse. When another male mouse ...

According to The Retrievers, a volunteer group dedicated to helping find lost dogs, the two animals — named Tucker and Maple, ...

Early life "luck" plays a pivotal role in shaping individuality and success, particularly for males, according to a new study in mice. In male animals, competitive social dynamics amplified small ...

"Everywhere we look, outcomes across populations are unequal," says Matthew Zipple, an evolutionary biologist at Cornell University. "In natural populations, there's a huge amount of variation in ...

Ultimately, this creates some winners and some losers in terms of survival and reproduction, says Matthew Zipple, a biologist at Cornell University. MATTHEW ZIPPLE: Everywhere we look, outcomes across ...
