How does evolution explain the similar legs in mammals and explain why the function differently?

Answer/Explanation:

These are examples of homologous structures. These are derived from common ancestors , however, they do not necessarily perform the same function. A good example is the vertebrate forelimbs like the ones shown here.

These limbs all have the same basic pattern of bones. They inherited this pattern from a common ancestor, but they now have different functions. This is an example of divergent evolution

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
