Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Other insects can not, but, a bumble bee has just enough weight to open up the snapdragon flower and pollinate. This adaption is ____
A
convergent evolution
B
Divergent evolution
C
speciation
D
coevolution
Explanation: 

Detailed explanation-1: -Mimicry should not be confused with other forms of convergent evolution that occurs when species come to resemble each other by adapting to similar lifestyles that have nothing to do with a common signal receiver.

Detailed explanation-2: -Convergent evolution occurs when species occupy similar ecological niches and adapt in similar ways in response to similar selective pressures. Traits that arise through convergent evolution are referred to as ‘analogous structures’. They are contrasted with ‘homologous structures’, which have a common origin.

Detailed explanation-3: -Homologous features Physical features shared due to evolutionary history (a common ancestor) are said to be homologous.

Detailed explanation-4: -Coevolution, or coevolution, is the reciprocal evolutionary change in a set of interacting populations over time resulting from the interactions between those populations. Usually, the interacting populations are different species, like plant–pollinator, predator–prey, or host–parasite.
