Audio/video recording of a lecture given by Dr. Bruce Lahn. He discusses newly discovered variants in two genes, one of which affects brain-size in humans. Because these variants have arisen very recently,...
Covers the three main ways in which evolution occurs, with chapters on genetic drift, mutation and natural selection. Gregor Mendel’s genetic theory is explained using coloured counters to represent genes.
A recording of the Francis Crick Lecture delivered by Julie Ahringer at the Royal Society on 24 November 2004. Over the past 20 years it has been discovered that all animals have many of the same genes and...
Uses live-action photography and computer generated animation to survey and explore evolution through natural selection and explores the role of genetic mutations in creating new species. Explains DNA and...
Examines the serious threat posed by antibiotic-resistant bacteria (suberbugs) and explains the evolutionary principles behind their development, why the problem is getting worse and how it is being dealt...
When biologist Mike Levine came across a picture of a mutant fruit fly, with two perfectly formed legs in place of its antennae, he had found the key to the toolkit nature uses to evolve new creatures. The...
In two parts. 1: Stages of Meiosis: Shows each step of meiosis, from prophase I through to telophase II. Explains how meiosis reduces by half the normal diploid number of chromosomes in a cell, to ensure...
Covers the three areas of transcription, protein synthesis, and mutations, using mainly computer-generated graphics. After an initial sequence showing the uses of proteins in living cells, the genetic code...
Looks at the field evidence for natural selection on the island of Madeira, where over 200 distinct endemic species of land snail have become adapted to a variety of habitats. Addresses the problem of...
The wings of butterflies display a striking colourful and varied array of patterns, but surprisingly few genetic changes are needed to produce this diversity. Dr John Turner of the University of Leeds shows...
