Human to fish, and back again: a brisk walk through our evolutionary history | Aeon Videos

Via stints as reptiles, rodents and fish with feet, the evolution of humans is as meandering as it is extraordinary. Reminiscent of a similar sequence from Carl Sagan’s iconic TV series Cosmos (1980), this short animation traces human evolutionary history back 550 million years to a small, primitive fish known as Metaspriggina, believed to be an early ancestor of all living vertebrates. The result is an enlightening overview, not only of our own curious lineage, but of the unpredictable turns that evolution can take for all species.

Darwinism—like every other natural process—devolves

Lehigh University biochemist Michael Behe, author of the 1996 book Darwin’s Black Box, which many consider to have sparked the modern intelligent design movement, is releasing a new book later this month entitled Darwin Devolves. The new book promises to be as revolutionary as his earlier books;

Do volcanoes or an asteroid deserve blame for dinosaur extinction? Asteroid/comet likely reignited Indian volcanoes 66 million years ago, but their role in extinction unclear — ScienceDaily

Scientists have obtained more precise dates for the Deccan Traps volcanic lava flows, linking peak activity more closely to the asteroid or comet impact 66 million years ago and the coincident mass extinction. But if greenhouse gases emitted before the impact created a hothouse climate that set life up for a fall when the impact cooled the planet, those gases did not coincide with the largest lava flows from the Deccan Traps.

Co-evolution: How does the need to sync development affect a system’s complexity? 

We are told that little is known about co-evolution and symbiosis, which prompts a question: How does the requirement for synchronization affect the overall complexity of the system?
