Evolution is regarded as a branching process, whereby populations are altered over time and may speciate into separate branches, hybridize together, or terminate by extinction.
Last December scientists announced the probable extinction of the first mammal because of climate change: the white lemuroid possum, now gone from Queensland, Australia.
By binding to certain glutamate receptors, D-cycloserine selectively enhances extinction, suppressing the effects of conditioned associations such as anxiety, addiction and phobias.
To date, Cullen and his team have restored 3,000 hectors of forest and tell us they have already seen at least half of native species using them including some animals at most risk of extinction.
