House sparrows were introduced to the cold climates of North America in 1852. Since that time, the bodies of sparrows in the north became larger than those of southern sparrows. What is the most likely cause of the change in northern sparrow body size?
If cold weather increases the rate of mutations in the genome, sparrows can mutate into longer organisms.
If larger sparrows cannot breed with smaller sparrows, they become isolated and form a new species.
If smaller sparrows cannot survive as well in cold weather, only sparrows with genes for large bodies will survive.
If sparrows shiver in the cold and gain muscle mass from the shivering, their body size will increase.
