This interactive simulation explores how genetic variability in a population leads to natural selection. In a series of simulations students explore which mutations are favoured by the selection agents of predators and food variety and which mutations are neutral; which traits change the survivability of an organism in ...

This radio interview discusses how Global Crop Diversity Trust is trying to conserve the biodiversity of the world's agricultural crops. A network of seed banks is being developed, together with a backup in a mountain in Norway. Just 10 or 12 crops dominate human nutrition. And there's turnover in varieties as crops are ...

This is a multilayered resource about the theories and evidence of the origins of the first modern humans in south-east Asia. It has four sections: Theories; The sout-heast Asian fossil record; The appearance of sout-heast Asian features; and The first modern Indonesians. The Related sections, Related items and Related ...

This 5 minute video segment from Catalyst shows a field trip with Dr Conrad Hoskin who has been scouring the tropical rainforests of north Queensland for frogs. He explains his research and the links between classification or taxonomy and evolution.

• TLF-IDM016691

This ABC In Depth feature article presents arguments about moving vulnerable species to cooler climates in advance of climate change is a controversial strategy, and whether it could be the best way of ensuring their survival.

• TLF-IDM016624

This lengthy and detailed video segment from Catalyst examines some of the key transitional fossils between species, the so called 'missing links'. Also included is an interesting story of a missing link that was discovered as a result of a hoax. This program includes extracts from Darwin's diaries in Australia.

• TLF-IDM016512

This 9 minute video segment from Catalyst explains the role of Australian Centre for Ancient DNA.It is an internationally recognised research centre for the study of minute traces of preserved genetic material - species studied date from a million years ago to more modern day mysteries... from mammoths to the Tassie devil, ...

• TLF-IDM016358

This 8 minute video segment from Catalyst is an excellent example of animal behaviour of locusts as a successful adaptation and how understanding the behaviour can potentially help reduce the damage they cause.

See how genes and genetic engineering work. Build models of DNA, and work out how it is copied as cells divide. Discover how the codes carried in the genes are copied and used to build proteins. See how gene splicing can be used to benefit human lives. For example, model the transfer of a human gene into bacteria, so they ...
