Answer:

The diversity of species

Explanation:

Darwin investigated the diversity of species by observing the physical differences between them. He concluded that all the species came from the same ancestor in common. And that the evolution is given by natural selection (or adaptation to the environment). Only specimens more adapted to the environment could survive, reproduce and pass their genetic traits to their offspring.

For example, the long neck of the giraffes is due to the fact that only the highest ones reached the leaves of the trees for food and with that they managed to survive.

Flowers </span>with no scent and small, pale petals will attract much <span>fewer </span>pollinators than flowers <span>with scent and large coloured petals</span>. This means those bushes would not cross-fertilize often with other roses.
However, they would not die from a lack of pollinators, nor would produce seeds by asexual reproduction. Also, they would not yield more fruit than the parent rose, their fruit would probably be very small,
