The speed of environmental change is very challenging for wild organisms. When exposed to a new environment individual plants and animals can potentially adjust their biology to better cope with new pressures they are exposed to – this is known as phenotypic plasticity.
Morphological analysis of the discovered specimen’s tooth shapes helped to determine that the specimen was one of the earliest nimravids dating back 37 to 40 million years. Sabertoothed nimravids were early members of Carnivoramorpha, but dogs and cats did not evolve from them. Changes in ecosystems may have driven the evolution and rise of nimravids.
