EVOLUTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A bumble bee has just enough weight to open up the snapdragon flower and get the nectar/pollen inside. Other insects cannot do this. This adaption is an example of ____
A
convergent evolution
B
co-evolution
C
divergent evolution
D
speciation
Explanation: 

Detailed explanation-1: -Examples of convergent evolution include the relationship between bat and insect wings, shark and dolphin bodies, and vertebrate and cephalopod eyes. Analogous structures arise from convergent evolution, but homologous structures do not.

Detailed explanation-2: -One of the most dramatic examples of convergent evolution is seen in photosynthesis-the process that plants use to capture energy from the sun and convert carbon dioxide and water into carbohydrates and oxygen.

Detailed explanation-3: -Mammals. Several groups of ungulates have independently reduced or lost side digits on their feet, often leaving one or two digits for walking. That name comes from their hooves, which have evolved from claws several times. For example, horses have one walking digit and domestic bovines two on each foot.
