From marmots to mole-rats to marmosets – studying many genes in many animals is key to understanding how humans can live longer
- Written by Amanda Kowalczyk, Ph.D. Candidate in Computational and Systems Biology, University of Pittsburgh

Much of longevity and aging research focuses on studying extremely long-lived species, including bats, naked mole-rats and bowhead whales, to find genetic changes that contribute to long life.
However, such work has yielded highly species-specific genetic...
