“The case that human language develops step by step through natural selection is weakened by the fact that no single language gene has ever been discovered.”
Wisnton Ewert has developed a model to explain the pattern of similarities in different organisms which mimics how computer applications inherit software from a diverse range of lower-level modules.
In “real time” they show the function of an enhancer in switching a gene from off to on.
A primary reason why many biologists never question the standard evolutionary model is their very limited training in mathematics.
Geneticist Wolf-Ekkehard Lönnig concludes that, “Sexual selection is not the cause of the long-necked giraffe.”
