Evolution Writ Large

Researchers have determined how long it takes for organisms to decrease or increase in size using fossil records as reference. The transformations seen in how evolution changes life forms over time never ceases to amaze. 

"Transformations can happen much faster in animals that live in the water. An increase from rabbit-sized to elephant-sized would take at least five million generations, but the equivalent change in whales takes half as many generations. Becoming smaller is also easier: dwarfing in elephants occurred 10 times faster than the equivalent increase to evolve large elephants. Image: Alistair Evans and David Jones"

"Kinda" makes a strong case for evolution if you ask me.
