It’s not easy for an individual human being, nor for the human species in general, to embrace the radical change implied in an existence as a smaller being. Growth, it seems, is the rhythm of life. But not for all life. Fortunately there are species of animals and plants that go against the tide and [...]

Fish Representatives

In most genetics research, Homo sapiens is represented by small fish like Danio rerio (zebrafish)  and Oryzias latipes (Japanese rice fish). Both are important model organisms, representing man in developmental genetics, neurophysiology and biomedicine. When we tinker with genes what happens to the fish is most likely to happen to us as well. If the [...]

Krill Adaptations

Because environments vary with both predictable patterns and with unpredictable but recurring events, ecologists have long been interested in the ecological adaptations that organisms use to survive periods in which the environment may be exceptionally harsh. One of the most interesting adaptations observed in the animal kingdom is full body shrinkage.
Krill has adopted shrinkage as [...]

Bergmann’s Rule

Songbirds in the US are getting smaller, and climate change is suspected as the cause.

A study of almost half a million birds, belonging to over 100 species, shows that many are gradually becoming lighter and growing shorter wings. This shrinkage has occurred within just half a century, with the birds thought to be evolving into a [...]
