Introduction: Reproduction: Dara O'Briain's Science Club (Series 1) (01:16)
This brief overview of reproduction orients viewers with excerpts from the upcoming program.
The Basics (03:00)
Follow the evolution of the science of genetics. Vocabulary includes: sperm, egg, chromosomes, DNA, and genes.
Professor Steve Jones (02:16)
O'Briain sits down to discuss the mechanisms surrounding sex with a geneticist. They discuss Lazzaro Spallanzani's experiment involving frogs and sperm.
Mass Migrations (02:37)
The current population is genetically different than it was 100 years ago because of the ease in which humans are moving around the world. The studio audience was photographed on their way in to determine attractiveness of the group.
Gene Comparisons (04:25)
A person's DNA is 99.9% identical to all other humans. Learn about the number of genes different species have. The studio audience participates in an experiment demonstrating how DNA can affect the sense of smell.
Decoding the Human Genome (03:41)
Science journalist Alok Jha investigates the usefulness of mapping the human genome. Professor Steven Rose explains why there have not been any diseases cured as a result of the project.
Just the Beginning (02:54)
Marketed as a huge success, mapping the human genome was just the first step to creating cures for diseases. The rest will be done over the next couple of decades.
O'Briain sits down with Alok Jha to discuss the political aspects of mapping the human genome. Learn about the colon cancer gene that can be identified due to the project.
DNA Samples (04:59)
Mark Miodownik uses 88% vodka to extract DNA from saliva samples taken from audience members.
Neanderthal Genome Decoded (03:18)
Ed Byrne visits the Natural History Museum to compare modern humans and Neanderthals.
DNA Test (02:33)
Byrne describes how to learn the percentage of Neanderthal DNA a person has. He then meets with Professor Mark Thomas to discuss whether Neanderthal and modern humans are the same species.
3% Neanderthal (02:34)
O'Briain sits down with Byrne to discuss the results of their DNA tests.
Tali Sharot explores the world of genetic expression. Epigenetic changes can override what is written in the DNA in mice.
Human Epigenomes (03:14)
Swedish scientists are studying whether or not humans can change their epigenomes. Professor Juleen Zierath shows evidence that exercise can alter the epigenome.
O'Briain sits down with Sharot to discuss epigenomes.
Symmetric faces are considered more attractive. View a composite image of all the audience members. Review the topics covered in the video.
