How 3D Changes in the Genome Turned Sharks Into Skates
...the evolutionary genomicist José Luis Gómez-Skarmeta assembled a diverse international team of genomics researchers and evolutionary developmental biologists. A team was needed partly because the first step would be to...
A Mutation Turned Ants Into Parasites in One Generation
...evolution of these weird, workerless social parasites,” Kronauer said. The Strength of Supergenes Little is known about the evolutionary history of the supergene on chromosome 13 that confers the social...
A New Idea for How to Assemble Life
...not their components.” To understand how assembly processes operate within these notional universes, consider the problem of Darwinian evolution. Conventionally, evolution is something that “just happened” once replicating molecules arose...
Is Perpetual Motion Possible at the Quantum Level?
...tie it back to that now? What did you get your chip to do? Khemani (26:53): Yeah, so any computation is just a time evolution. OK? But if you want...
How Pools of Genetic Diversity Affect a Species’ Fate
...save the species,” Steiner explained. “But that’s not enough if you think about it. When you talk about species, you’re not considering the whole evolutionary potential of all the different...
Primitive Asgard Cells Show Life on the Brink of Complexity
...is now an evolutionary microbiologist at the University of Amsterdam, set out to find what they hoped would be an evolutionary missing link. Biologists had long used genetic data to...
Animal Mutation Rates Reveal Traits That Speed Evolution
...can begin to answer questions about which traits most influence mutation rates and the pace of evolution. “There are things that affect the rate of evolution, [but] we don’t know...
How a DNA ‘Parasite’ May Have Fragmented Our Genes
...evolution of genomic complexity. One example involves a theory of intron evolution developed by Michael Lynch of Arizona State University in 2002. Models suggest that in species with small breeding...
Dinosaur Bone Study Reveals That Not All Giants Grew Alike
A survey of prehistoric bones reveals that T. rex and some of its cousins had more than one way to reach enormous sizes. Evolution may have preserved that variation in...
