question 8: how far may we go in manipulating plants?

As scientists successively reveal the genetic makeup of plants, they are also creating sharper tools for altering parts of the genetic code. What implications does this have? Advances are taking us further and further from what is 'natural'. Can we keep up?  Read more

question 38: how unnatural are our domestic animals?

The evolution of wild animals into tame domestic ones shows how man has controlled animal biology and our own culture down the ages. No domestic animals can in fact be called 'natural' – and we may wonder how far this development can go. Which animals will be the pets of the future?  Read more

question 41: what is the largest living organism on Earth?

The elephant is the largest land animal, as we all learned in school. But who tops the size league if we include all land organisms, not only animals? Biologists are not entirely sure, but it could be a deciduous tree, the unassuming poplar.  Read more

question 46: only 46,400 species to go?

A marathon 20-year project is underway in Sweden. It's goal? To describe all the multi-celled living organisms in the country. Every last creepy-crawly and weed is to be tracked down, scientifically investigated and then described and illustrated in a gigantic reference work for the general public. Carl Linnaeus would be rubbing his hands with glee!  Read more
