...(03:05) And I think that it’s, it’s just something that’s always been fascinating to me every time I’ve encountered it. Just seeing the discussions around how the ultimate evolution of...
What Makes Life Tick? Mitochondria May Keep Time for Cells
...evolution exploits in creating new species. However, what sets the tempo of an organism’s growth has remained a mystery. “Our knowledge of what controls developmental timing has really lagged behind...
Bats Use the Same Brain Cells to Map Physical and Social Worlds
New research in social bats raises the intriguing possibility that evolution can program the brain’s “place cells,” which are typically associated with location, to encode all kinds of environmental information....
Oxygen and Stem Cells May Have Reshaped Early Complex Animals
...rapid proliferation and diversification of animal life that, half a billion years ago, forever changed Earth’s evolutionary landscape. In spite of Påhlman’s initial reservations, however, the pair has collaborated over...
Chronological Clues to Life’s Early History Lurk in Gene Transfers
https://doi.org/10.1111/pala.12211 To date the branches on the evolutionary tree of life, researchers are looking at horizontal gene transfers among ancient microorganisms, which once seemed only to muddle the record. Scientists...
Why Nature Prefers Couples, Even for Yeast
...think about two biological sexes: male and female. But before the evolution of eggs and sperm — before sex cells began to diverge in size and form — organisms couldn’t...
Artificial Intelligence Finds Ancient ‘Ghosts’ in Modern DNA
