What was going on before DNA was discovered?

Answer 1

Lets just say they were SHOCKED to find a code inside every cell that commanded it to form a 4 chamber heart, its spacial location, along with its electrical and pressure system.

They were being told that cells couldnt "know" anything--yet they refused to posit what amounted to computer code because that would indicate design. Now, they basically see the dart on the wall and draw a bulls-eye around it claiming they knew it all along.

Just as in physics, some biologist are now positing multiverses as the only explanation for the insurmountable odds that DNA or abiogenesis could occur from chance.

Answer 2

Before the discovery of DNA, scientists had limited understanding of heredity and the mechanisms involved in passing on traits from one generation to the next. The discovery of DNA in 1953 by Watson and Crick revolutionized Biology by providing insight into how genetic information is stored and transmitted in living organisms.
