A look at the taxonomic classification of the tomato plant and the origin, history and development of tomatoes.

Viruses are not living things - so where did they come from? Scientists have proposed three different hypotheses.

It took several scientists building on each other’s discoveries to come up with Cell Theory - one of the cornerstones of biology.

Scientists have accumulated so much evidence in the theory of evolution that it is one of the most widely-accepted theories in science.

Ever wonder how fish survive in the cold waters of the Arctic and Antarctic? It’s partly because of a brilliant evolutionary adaptation.

Radiocarbon dating is a method of radiometric dating. Learn how archaeologists use carbon isotopes to find the age of organic materials at archaeological sites.

Cloning makes it possible to bring extinct species back to life. But is that a good idea?

A study on bird feeders and beak sizes shows how an everyday human activity can affect the evolution of another species.

Some dung beetles use alternative reproductive tactics to increase their chances of finding a mate. Learn what this tells us about evolution and biodiversity.

Learn how geologists used radioactive dating to uncover geology shared by both Canada and Australia.

How do different populations adapt to their environment? Let’s explore this concept through guppy speciation.
