TVs and Corvettes aren't changed at random to make the design better. That approach doesn't work, even with a highly intelligent selection process. Random changes will never turn a radio into a television. There has to be an intelligent purpose coordinating many design changes at once. Some irrational people question these dates for the two world wars, citing historical documents that claim much more recent times for these events.
Historical documents are notoriously untrustworthy because of human bias.
The evolutionary evidence of the radio into the television proves that these two wars could not have happened within a few decades of each other because the evolution of the television took two million years.
