Deep in the oceans dwell creatures that can evade many of the evolutionary drivers of life on land – and they remain seemingly unchanged through time.
Certain combinations of genetic material are being conserved through the generations.
Our study on weird ancient marine animals called radiodonts supports the idea that vision played a crucial role during the Cambrian Explosion, a rapid burst of evolution about 500 million years ago.
When a male bluehead wrasse is removed from the group he dominates, the largest female changes sex, rapidly transforming ovaries into sperm-producing testes. Molecular research shows how.
New research shows shallow, near-land seas similar to Bass Strait were critical in the early days of fish evolution. These are the waters we need to protect now to ensure ongoing biodiversity.
Brindabellaspis had eyes on the top of the head, facing upwards, and a skull stretched into a long and broad snout. Although around 400 million years old, it was clearly a specialised fish.
