Natural latex, or rubber, comes from the sap of rubber trees. Native to the Amazon region of South America, they had long been a Brazilian monopoly, and the boom in wild rubber had made many remote jungle towns rich, until thousands of seeds of the tree were smuggled out by an entrepreneurial Brit, Henry Wickham. …
A In 1980 a team of researchers were analysing soil samples at what was then known as the KT boundary. The K is misleading, as it actually refers to the cretaceous era, while the T refers to the tertiary era. What made geologists originally place a division in that distant time, some 65 million years ago, …

Our primitive ancestors left many paintings on the walls inside caves. Additionally, inside and near these places there is evidence of fire pits, and refuse and burial sites. However, one could equally imagine this same evidence of daily life on exposed cliffs or hillsides, on trees or animals skins, and beside rivers and coastlines. Such …
Any specific study of words and language almost invariably has an obscure name, and that includes the study of people’s names themselves.

In today’s climate of New Age spiritualism, animal rights, and Mother Earth naturalism, confirmed meat-eaters must necessarily be categorised as selfish, environmentally-irresponsible, spiritually-deprived gluttons, whose dietary desire is akin to cannibalism.

There is a strange irony about the blue whale. With fully grown adults reaching up to 30 metres long, and weighing in at almost 200 tons, it is not only the largest animal in the world, but also the largest to have ever existed. Yes, not even the most imposing of the dinosaurs from the …
