The Grants found that during food shortages the difference of one millimeter in the size of a finch's beak could determine its life or death. It also gives the reader an understanding of how evolution works over both long and short stretches of time.
Over time, as advantageous traits and variations become more common, future generations of that species might become markedly different from previous ones— even becoming a different species altogether.
Inception of Darwin's theory While still a young man, Charles Darwin joined the scientific elite. A few small land vertebrates, depending on ocean currents, may arrive on floating rafts of vegetation.
