Answer:
Darwin and Lamarck's theory is different but they were also very similar. Both of them thought that the organism changed, and they are very helpful for the organism to survive. These characteristics are also passed to their young generation. 
Darwin theory state that an organism gets the helpful variation before the changes in the environment, Lamarck's theory said that organism gets variation after the change in the environment.
Lamarck's stated that giraffe got long neck when the food on the ground ran out. In order to get the food they stretch out their neck to get food. Darwin thought organism changed by chance, at the time when they are born and before the change in the environment.

Explanation:
In 1953 James Watson and Francis Crick are responsible for determining the structure of DNA. James and Watson proposed that the DNA is made up of a double polynucleotide chains that are twisted around each other to forming a helical structure. The two DNA chains runs anti-parallel in opposite direction to each other. Like the structure of the ladder.
The answer is James Watson and Francis Crick
