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...
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...
Cell by Cell, Scientists Map the Genetic Steps as Eggs Become Animals
...their expression programs over the course of evolution. The conservation of the proteins at the sequence level seems to have no connection to the conservation of their expression in evolution....
Jellyfish Genome Hints That Complexity Isn’t Genetically Complex
Jellyfish didn’t need novel genes to take an evolutionary leap in complexity. An overarching theme in the story of evolution, at least over the past half billion years or so,...
Giant Genetic Map Shows Life’s Hidden Links
...evolution. As beautiful as the bird’s-eye view of the cell is, this work goes beyond biological voyeurism. This information can tell us about the evolution of the cell and, potentially,...
