Evolution

Make SHARK (fish) evolve into TIGER (mammal) by changing one letter at a time. Each change must produce a valid word in the English language. But there is a catch. The evolution must go through VIPER (reptile) and RAVEN (bird). No word can be used more than once.

SHARK ---- VIPER ---- RAVEN ---- TIGER
