Question

Question 31 3 pts Columbine flowers are characterized by long nectar tubes called spurs. Columbine pollinators generally have long tongues. The long spurs in columbine flowers and the long tongues of columbine pollinators is likely a result of which process? O co-evolution shared derived characters convergent evolution O horizontal gene transfer

Answer 1

Ans.

• The co-evolution theory of Darwin dscribes the way through which natural selection may be responsible for the development of very long nectar spurs in flowers.
• According to this theory, natural selection would favor plants with the longest spurs and longest tongue pollinators as well.
• This never ending process of co-evolution continuously drived the spurs of plants and pollinators tongues to significantly great length.
• This co-evaluation is held responsible for shaping the relationships between food-rewarding flowers and pollinators of plants.
• Thus, it can be said that the long spurs in columbine flower and the long tongue of columbine pollinators is likely a result of the process of co-evolution.
