The flowering plants (angiosperms) are the most diverse group of land plants. The first flowering plants known to exist are from 160 million years ago. They diversified enormously during the Lower Cretaceous and became widespread around 120 million years ago. It is generally assumed that the function of flowers, from the start, was to involve animals in their reproduction processes.
By so doing plants greatly improved their reproductive efficiency and genetic diversity. Many animals contribute, insects, birds, bats monkey’s etc. interestingly red flowers will be pollinated by animals that can see ‘red’ in the spectrum, (like birds and monkeys). Rarely will they be pollinated by insects which can see ultraviolet, but not red.
