The column Zebra Crossing was concieved as a shortcut across the information highway — at a time when dial-up was the only internet option, even for privileged users in first-tier firms.

948 / From fish to four-limbed animals

Tetrapods are four-limbed animals. Therefore the discovery of a “tetrapod-like” fish called Elpistostege is intriguing. The nearly complete fossil specimen says a lot about one of the most significant events in the history of life — the evolution of fishes…
