Arihood Nolan English 102 Mardy Philipian September 19 Johnston on Darwinism In Death of Darwinism author George Sim Johnston states that there is controversy over the evolutionary theory of Darwin not the concept of evolution Speaking on this topic Johnston tries to point out some of the problems with Darwins theory of evolution by giving other scientist views and views of his own Johnston uses an antagonistic Rhetoric style by presenting Darwins theories then breaks them down and counters them Johnston first starts out by presenting Darwins main theory of natural selection He then gives an experiment of Darwins that involved the select breeding of pigeons Darwin based part of his theory of natural selection from this experiment claiming that all forms of life came from a single organism at the beginning of time Johnston argues the fact that Darwin only observed micro-evolution Micro-evolution is small changes that happen to a species over time Johnson agrees that micro-evolution takes place but what he disagrees with the fact that Darwin relies on the theory that a build up of micro-eveloution results in macro-evolution Macro-evolution is relatively large jumps in evolution such as amebas to reptiles to mammals Darwin claimed that over long periods of time that many small changes would eventually result in macro-evolution with no empirical evidence Johnston claims that if Darwins theories were correct that there should be fossils to prove it This Meaning that there should be slight changes between the early species fossils and later species fossils Fossil records find that within a certain species there are slight changes then that species disappears 99 out of 100 are extinct instead of evolving into a new species Johnston then uses a quote from paleontologist Steven Stanly to back his thoughts up The fossil record does not convincingly demonstrate a single transition from one species to another Johnston argues that even though changes occur because of breeding in experiments these changes
