Many years ago, a scientist grew pea plants that
produced wrinkled peas. the peas from these
plants produced new plants that also produced
wrinkled peas. the scientist concluded that
something in the parent plants was being
transmitted to the next generation. this
discovery is now known as
(1) genetic engineering (3) heredity
(2) biological evolution (4) natural selection
