BBCnews is carrying a report on a new fossil find that illuminates an important part of fish evolution:

The animals lived in a time when Africa was in an ice age, and before any animals had colonised the land. According to the team, they lived in a shallow sea fed by melt waters from receding ice-sheets.

Interesting in one respect because, until now, fish evolution was thought to have ocurred elsewhere. Interesting in another because, at this point in history, one of these fossil fish (either in Africa or elsewhere) eventually lead to us.
