In Betty Smith’s description of the tree of heaven (Ailanthus altissima), also known as the “ghetto palm,” the tree is contrasted with the memory of a school poem that evoked the “forest primeval” with its “murmuring pines and hemlocks.” For Smith, writing in the early 1940s, the presence of this tree was a marker, or even harbinger, of neighbourhood decline. The tree of heaven se…

For more than 150 years, since the publication of On the Origin of Species, biologists have focused on understanding the evolutionary chronicle of diversification and extinction, and the underlying evolutionary processes that have produced it. Although progress in evolutionary biology has been steady since Darwin’s time, developments in the last 20 years have ushered in a golden era of evolut…
The term cell is derived from the Latin cella, meaning storeroom or chamber. It was first used in biology in 1665 by the English botanist Robert Hooke to describe the individual units of the honeycomb-like structure he observed in cork under a compound microscope. The “cells” Hooke observed were actually the empty lumens of dead cells surrounded by cell walls, but the term is an apt one be…
