Here is a good example of how ineffective the existing theory of evolution is for predicting the future. Based on extrapolation of the theory, from the observation of apes and the continuity with humans, the theory predicts that natural human behavior involves promiscuity.
I will use a simple rational theory which state that natural should be self sustaining and not require propping up by science and medicine, since nature does not have these mops. A real rational theory should be able to predict types of human behavior that are self sustainable even without science smoke, mirrors and mops to create an illusion for theory support.
Promiscuous behavior might be natural for apes, since apes don't use or require mops to clean up the mess. This behavior may be fun for humans, but the modern data indicates it is not sustainable for humans without mops. Therefore it is not natural for humans.
Evolutionary theory is not rational science but has had to depend on zoo keepers to create the illusion. It needs an upgrade that could have avoided this error.
Relative to evolution this data would imply a discontinuity between ape and human behaviors. We can use the rational standard of natural human behavior needs no mops, to show that evolution is not too useful when it comes to predicting a wide range of natural human behavior.
