DNA Jumps Between Animal Species. No One Knows How Often.
...an evolutionary genomicist at Reed College in Portland, Oregon, believes these cases of horizontal transfer still have “a pretty big wow factor” even among scientists, “because the conventional wisdom for...
Single Cells Evolve Large Multicellular Forms in Just Two Years
...his colleagues report that over the course of nearly two years of evolution, they have induced unicellular yeasts to grow into multicellular clusters of immense size, going from microscopic to...
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...
How Did Altruism Evolve?
...classical notion of evolutionary biology where everything is just about selfish survival. I think you’ve explained well why there would be evolutionary pressure in the longer term to have this...
The Hidden World of Electrostatic Ecology
...evolution has fine-tuned this electric sense. Electrostatics may turn out to be an evolutionary force in small creatures’ survival that helps them find food, migrate and infest other living things....
The Year in Biology
...molecular changes manifest in evolution and everyday biology. Biologists Meet the AI Revolution In 2024, hardly a week could go by without some big new paper related to Google...
Scientists Re-Create the Microbial Dance That Sparked Complex Life
Evolution was fueled by endosymbiosis, cellular alliances in which one microbe makes a permanent home inside another. For the first time, biologists made it happen in the lab. Far from...
Insects Conquered a Watery Realm With Just Two New Genes
...what’s needed to provide a complete answer to how phenotypic evolution occurs. “The integrative, interdisciplinary nature of this demonstration is what’s striking here,” said Ehab Abouheif, an evolutionary developmental biologist...
A Mathematician Who Decodes the Patterns Stamped Out by Life
...Other collective organisms such as slime molds must contend with evolutionary pressures both on the whole and on individuals. And in still larger systems like the African savanna, evolution shapes...
