Islands Spark Accelerated Evolution

-Clonogenic growth (colony-forming efficiency, CFE) of i.v. injected allogeneic W256 tumour cells in the lungs was markedly enhanced by treatment of rats with x-naphthyl thiourea (ANTU) injected i.p. from 2 h before to 2 h after the tumour cells. ANTU specifically increases pulmonary vascular permeability in adult rats and causes acute pulmonary oedema and pleural effusion. Inhibition of drug t...

Mammalian Evolution: A Jurassic Spark

There is increasing evidence that early mammals evolved rapidly into a range of body forms and habitats, right under the noses of the dinosaurs.

On the Evolution of Islands

Suppose we have n cells arranged in a ring, or alternatively, in a row. We pick a cell at random and mark it; we pick one of the remaining unmarked cells at random and mark it; and so on until after n steps each cell is marked. After the k'th cell has been marked, the con guration of the marked cells de nes some number of islands separated by seas (See Figure 1). An island is a maximal set of a...

Introduction. Evolution on Pacific islands: Darwin's legacy.

Charles Darwin stepped ashore on the Pacific Island of San Cristobal in the Galápagos archipelago on 17 September 1835. No doubt grateful to be on the steady, dry land, the young Darwin was at first unimpressed by the landscape ‘Nothing could be less inviting than the first appearance’ (Darwin 1839, p. 454). Nevertheless, Darwin was to make important inferences from the observations of island b...
