Question

explain industrial melanism with the example of Biston bitularia​

Answer 1

Jarwinian evolution in action are

lescribed. Four categories of criticism of

he case are then evaluated. Criticisms of

xperimental work in the 1950s that

entered on lack of knowledge of the

behavior and ecology of the moth, poor

xperimental procedure, or artificiality in

xperiments have been addressed in

subsequent work. Some criticisms of the

vork are shown to be the result of lack of

inderstanding of evolutionary genetics

ind ecological entomology on the part of

he critics. Accusations of data fudging

ind scientific fraud in the case are found

0 be vacuous. The conclusion from this

inalysis of criticisms of the case is that

ndustrial melanism in the peppered

noth is still one of the clearest and most

asily understood examples of Darwinian

volution in action and that it should be

aught as such in biology classes...
