Nothing Comes From Nothing

Deep sea fish such as the black swallower, manefishes, sporting spiky fins are close relatives to mackerels and tuna even though they have totally different body shapes and lifestyles.

The team, led by Dr Masaki Miya at Chiba Natural History Museum in Japan, suggests that this extended family of fishes might owe its success today to the devastating extinction that marked the demise of dinosaurs and many other creatures 66 million years ago.

It is common ancestors which lived in deep ocean that help them to survive from the ancient extinction. And then it colonized in shallower water to produce species we see today which are very different from each other.

We prefer to think of the extinction as a damage of biodiversity. However, in fact, it is the extinction that gave other species opportunities to come into being. Nothing comes from nothing. For instance, mammals definitely took advantages from the extinction of dinosaurs. We can notice that a huge amount of mammal diversity flooded in.

It happens not only in nature but also in cities. Reconstructions of downtown comes from the Great Fire in Chicago. Destruction had done more good than harm for imposing strict new buildings and driving up the price of downtown real estate.

    To take the reconstruction of Chicago after the 1871 fire as analagous to a long-term process of extinction and survival raises questions. Is rebuilding a city in a matter of years (a result of human agency) comparable to the restoration of species diversity (prior to the existence of humans) over millions of years?
