What science was developed later which was found to support darwins theory

Nuclear fusion is the source of energy for stars. besides hydrogen, which other element is most likely also common in stars?

The human eye contains a molecule called 11-cis-retinal that changes shape when struck with light of sufficient energy. the change in shape triggers a series of events that results in an electrical signal being sent to the brain that results in vision. the minimum energy required to change the conformation of 11-cis-retinal within the eye is about 164 kj/mol.
