Who provided x-ray diffraction photographs of purified dna fibers that suggested a helical structure with a consistent diameter of about 2 nm and a complete helical turn every 3.4 nm?

As scientists have investigated evolution from a variety of fields, they have found that some of darwin's orginal ideas were inaccurate or incomplete. t explanation provided by evolution was updated each time to reflect the new information they found. what does this suggest about the theory of evolution? it has become a stronger and clearer theory as new information is collected.
