Early humans evolved in ecosystems unlike any found today

October 7, 2019

To understand the environmental pressures that shaped human evolution, scientists must first piece together the details of the ancient plant and animal communities that our fossil ancestors lived in over the past 7 million years. Because putting together the puzzle of millions-of-years-old ecosystems is a difficult task, many studies have reconstructed the environments by drawing […]



Mapping the Genome Jungle

March 6, 2018

From a bat’s wings to an elephant’s cancer resistance, an interdisciplinary team of scientists at University of Utah Health are using animals’ unique traits to pinpoint regions of the human genome that might affect health. The results of this project are available in the March 6 issue of the journal Cell Reports. The research team […]



Genomes in flux

February 6, 2017

SALT LAKE CITY – Evolution is often thought of as a gradual remodeling of the genome, the genetic blueprints for building an organism. In some instances it might be more appropriate to call it an overhaul. Over the past 100 million years, the human lineage has lost one-fifth of its DNA, while an even greater […]



Biologists follow ‘fossilizable’ clues to pinpoint when mammal, bird and dinosaur ancestors became athletes

December 22, 2016

Many mammals and birds are remarkable athletes; mice work hard to dig burrows for protection and sparrows fight gravity with each flap of their wings. In order to have the energy to sustain vigorous exercise, the body’s tissues need a steady supply of oxygen, and red blood cells (RBCs) are the center of the oxygen […]
