СКАЧАТЬ of escape. They have allowed certain insects to survive in extremely difficult or dangerous circumstances. Insects are complex creatures that interact with each other, with their food and with enemies who see them as food. And they get up to some very strange things. They seem to be dancing, skulking or hiding. They brave danger or run like cowards. Some nurture and some murder; some commit suicide. They may appear very clever or extremely dim. Some steal and some give gifts. What is the biological explanation behind these apparently odd behaviours?

      Extreme Impact. Humans now reckon themselves to be the dominant life form on Earth, but we have been around for only a few hundred thousand years. Insects were here over 300 million years earlier. Humans, the mere junior upstarts, now come into conflict with a much older and better-established group of organisms. And despite our modern sophistication, we cannot escape such tenacious and apparently determined animals. They invade our fields, our houses and even our bodies. Some we can tame for our own uses, but with others we are still at war.

      Insects are both awful and awe-inspiring, certainly worthy of our respect and our study. They give us a window on the natural world through which we can see, and attempt to understand, the environment in which we live, indeed of which we are an integral part. The huge numbers of insects, and their depredations on human food and health, are sometimes bemoaned. In reality, they form a vast biomass, and it is a wasteful shame that insects form an insignificant part of the human diet. We may not eat them very often, but insects offer a more philosophical sustenance – food for thought. In their study, there is a veritable feast for the mind.

NAME Rhyniognatha hirsti
LOCATION fossil discovered in Aberdeenshire, Scotland
STATUS oldest known fossil of an insect

      Most insects are very small, very delicate and very edible, so the fossil record they have left behind is extremely poor. The majority end up as prey for other animals, bitten, chewed and digested away. Where their remains are not eaten, there are no large bones to be preserved, and even the toughest of insect shells are made of highly biodegradable compounds. As a result, it takes some pretty special circumstances for insect fossils to form, and they are thoroughly scrutinised when found. Or at least they should be.

      Until recently, the oldest acknowledged insect-like fossil was an ancient relative of modern springtails. These are wingless soft-bodied creatures that are not now classed as insects but as a sister group within the subphylum Hexapoda (six-legged arthropods). The fossil was found in 1919 by the Reverend W. Cran in the old red sandstone deposits (also called the Rhynie cherts) at Rhynie in Aberdeenshire, Scotland, which date from 407-396 million years ago. It was finally described in 1926 by three paleontologists, S. Hirst, S. Maulik and D.J. Scourfield, who aptly named it Rhyniella praecursor.
