At the end of the Palaeolithic period, the climate was very similar to ours today, and this led to a change in the flora and fauna. Large animals, typical of cold climates, moved north and some groups of hunters followed them. Those who remained adapted to the new situation. The hunting and gathering of the Palaeolithic period continued into the Epipalaeolithic. Tools became more precisely shaped and bows and arrows made it easier to hunt small and medium-sized animals, such as rabbits, birds and deer. Molluscs were gathered in coastal areas. Artistic expression took the form of paintings and engravings.
