Darwin's branching "tree of life" diagram made for a nice, simple, easy-to-understand, convenient myth. It has sent scientists on a wild tree chase ever since.
Some very small organisms can produce global effects, such as the tiny crustaceans that stir the oceans every night. What would the oceans be like without life? If minerals, gases and nutrients had to mix by diffusion, the process would be very slow. Wind and currents could help somewhat. Now, Houghton et al., publishing in […]
City planners need to plant more trees in urban areas, but the benefits go beyond beautifying pavement. Urban areas occupy 4% of the land surface of the planet, says Theodore A. Endreny in a Comment article in Nature Communications. That may strike readers as surprising, given most people’s attention to cities for work, travel and […]
Observations are just props. The play is, “The Evolution of Whatever” or “How Whatever Evolved.” Now playing in science media near you. As a play, Darwinism has two subplots: natural selection and sexual selection. With a little creative screenwriting, any observation in nature can be fit into either or both subplots, provided the perhapsimaybecouldness index […]
A new study of elephants, mammoths and mastodons show they were all interfertile or capable of hybridization. Our present world is impoverished of elephants, or “elephantids” as scientists dub the family. Mammoths and mastodons roamed throughout America and Asia, evidenced by the massive fossil beds, where millions of mammoth bones can be found in permafrost. […]
