The Egg & Sperm Race

Author(s): Matthew Cobb

History

Where do we come from? For thousands of years we really had no clue how living things were created - great thinkers like Aristotle and Plato had attempted to explain what became known as the problem of 'generation', but neither really had the tools or the insight to solve the mystery. The result was a wealth of weird and wonderful ideas about the components necessary to create new life - blood, 'vapours', strange pulses in the air. It was also widely accepted that animals could breed different species; the notion that two sheep can only make another sheep is a surprisingly modern idea. But all this confusion changed in a flurry of discovery in the mid-seventeenth century. In just a decade, a group of young scientists in Europe established the existence first of the human egg and then of the human sperm. At last, the building blocks were in place - although, in one of the great ironies of science, it would be another 150 years before someone worked out how fertilisation actually took place.
