Chirality confers individuality, recognition, and specificity. All of these qualities are vital in the struggle for existence.
As humans we are a lot less symmetrical than we appear. We have dominant hands, ears and even eyes. How did that evolve and why does it matter?
In the first of his CHRISTMAS LECTURES, Richard Dawkins explores the origins of life. Beginning with a look at our ancestry, he shows how the probability of our existence is very small.
In his second lecture, Richard Dawkins explores the world of designoid objects. He reveals how the evolution of these beautiful creations has relied on natural selection over generations of time.
In this lecture, Richard Dawkins argues against an anthropocentric view of nature and instead presents a rational case for its evolutionary development.
In his third lecture, Richard Dawkins uses the metaphor of a tall mountain - Mount Improbable – to explain evolution. When we look at Mount Improbable, its peak seems insurmountable.
In his final lecture, Richard Dawkins examines the genesis of ‘purpose’ within the universe and relates this to the development of consciousness within the human brain.
The use of echos is a communication method often used when visibility is poor. Two well known examples are radar, using radio waves, and bats which emit high frequency sounds.
All animals depend on communication for both reproduction as well as social reasons. They communicate using a variety of different and sometimes surprising ways.
Genetics will eventually identify all the human genes and their functions. How far will this take us in explaining the infinite variety of mankind?
Cancer can occur when the regulation of cells in the body goes astray. Any tissue can be affected but some are more likely to become cancerous than others.
The body protects itself against infection by bacteria, viruses, molds and parasites by having a system for recognising these invading organisms as foreign.
How can we isolate and study genes one at a time?
Living matter is made from a complex mixture of chemicals, some small like salts, sugars and fats and others large and complicated such as protein and DNA.
Everybody looks different, apart from identical twins, and many of the differences are inherited.
