For more than a century, biologists have appealed to Darwinian natural selection to explain how living organisms adapt to different environments. But research over the last several decades has consistently dethroned Darwin’s view of natural selection.

New human organs are rarely discovered, but that’s what several astute scientists recently accomplished at Sweden’s Karolinska Institutet’s Department of Medical Biochemistry and Biophysics.¹ The organ is a loosely connected mesh of cells in the skin’s nervous system that are sensitive to painful conditions straining the skin.

Komodo dragons are the largest lizards in the world and a top predator on the remote Indonesian islands they inhabit. Their sensory system allows them to detect large prey, such as deer, over seven miles away. Although Komodo dragons are cold-blooded reptiles, they can rapidly increase their metabolism to near-mammalian levels for amazing bursts of speed and even long strenuous runs.
