A team of researchers have found evidence that the western long-beaked echidna isn't extinct in Australia and may still be roaming in the West Kimberley region. There is a small and declining population of western long-beaked echidna in Papua New Guinea [pictured] - finding a surviving population in Australia could help researchers save the species.

Genes can jump from snakes to cows, according to new research. An Australian study suggests a quarter of a cow's genetic makeup originated in reptiles, challenging conventional thinking that DNA in complex organisms is only passed from parent to offspring. The scientists aren't sure how the DNA passed between the species, but suggests ticks may be responsible.
