What Did Darwin Actually Do? (05:17)

FREE PREVIEW

Charles Darwin noticed unique animal adaptations on the Galapagos Islands in 1835. He published his theory on natural selection 20 years later, providing a mechanism for evolutionary theories.

Are We All Mutants? (04:25)

In the 1850s, Gregor Mendel discovered how genetic traits were inherited. In the 20th century, we discovered molecular mutation. Mutations are random and lead to diversification.

How am I Related to a Mouse? (03:20)

Approximately 85% of the "recipe" for Homo sapiens is the same as a mouse; all organisms share certain genetic sequences. Experts discuss "The Evolutionary Cookbook" and L.U.C.A.

Which Came First? The Dinosaur or the Egg? (03:36)

Embryos possess all the biological know-how of species development. Experts discuss genetic waste; recessive genes; and atavisms.

War...What is it Good For? (04:17)

The Earth houses an arms race between predator and prey. Experts use the Pit Viper and possum to explain co-evolution. Co-evolution can lead to mutualism.

Am I Hot or Not? (03:12)

Some species measure attractiveness intra-sexually; others compete inter-sexually. The Micronecta Scholtzi has the loudest mating call on Earth. Experts discuss asexual reproduction.

What Has Geography Got to do With Evolution? (04:31)

Geography can interrupt gene flow and contribute to speciation or unite species in convergent evolution. Currently, there are approximately 8.7 million known species.

Is Life a Marathon or a Sprint? (04:37)

Darwin believed gradualism dictates evolution. Experts discuss the sudden diversification during the Cambrian Explosion and punctuated equilibrium.

Why do Species go Extinct? (03:19)

Approximately 99% of all species that have ever lived are extinct. Man and invasive species contribute to extinction but evolution is the biggest factor. Extinction is a fundamental part of the evolutionary process.

Can We Create Life? (04:35)

In 2011, scientists announced a plan to resurrect the wooly mammoth. Experts discuss the challenge of DNA quality. In 2010, scientists produced the first synthetic life form.

Evolutionary Review (01:37)

Life diversified and adapted to every corner of Earth from L.U.C.A. Since Charles Darwin's book, there has been no evidence to disprove evolution.
