"Nothing in biology makes sense except in light of evolution." Despite Theodosius Dobzhansky's succint description of natural selection at the core of biological research since Darwin's fateful trip to the Galapagos, evolutionary biologist Michael Lynch respectfully dissents, asking "whether natural selection is a necessary or sufficient force to explain" the complexity of multicellular organisms we see today, where mutation, recombination and genetic drift are often overlooked, but critical factors in evolutionary theory and understanding.

Scientists in Australia have discovered a new gene. Called BRCA3, this genetic mutation causes up to 10% of the breast cancer cases which run within families. This breakthrough completes the search for the trilogy of gene mutations. The first two gene mutation markers were discovered in 1994 and 1995 respectively.
