It was the structure of DNA. Watson and Crick stole the credit from a woman whose name I can't remember, but basically she took really long exposure photographs (24 hours for some) and saw an X shape, which was the corresponding sign of a double helix. It was a pretty complicated method she was using and nobody had thought of using it for DNA research until then.
1) The limbs of a bat and the forelimbs of a bird is an example of Analogous structures
2) The arm of a human and the arm of chimpazee is an example of Homologous structures
3) Frogs and salamanders is an example of Homologous structures
<span>Homologous structures, are organs or systems of different living beings
that have a common origin, but different adaptations. For example, the
extremities of a dog and a dolphin, are homologous, have similar bones, only
that some adapted to the race and others to swimming. On the other hand,
analogous structures are organs or systems of different living beings that do
not have a close origin in common, but are adapted to the same environment, for
example, fins of fish and dolphin fins, the function is the same, the origin is
different; or the wings of birds and the wings of insects.</span>
