Darwin's theory of evolution is a theory in crisis in light of the tremendous advances we've made in molecular biology, biochemistry and genetics over the past fifty years we now know that there are in fact tens of thousands of irreducibly complex systems on the cellular level.
Course overview: in each session of this course, we introduce concepts in evolution through ibiology videos and accompanying educator resources fundamentals such as darwinian evolution, genetic variation and natural selection are covered. Darwin proposed that evolution could be explained by the differential survival of organisms following their naturally occurring variation—a process he termed natural selection according to this view, the offspring of organisms differ from one another and from their parents in ways that are heritable—that is, they can pass on the .

Origins and biochemical evidence by studying the basic biochemistry shared by many organisms, we can begin to piece together how biochemical systems evolved near the root of the tree of life. Here’s a brief summary of the evidence that supports the theory of evolution by natural selection: biochemistry is the study of the basic chemistry and processes that occur in cells the biochemistry of all living things on earth is incredibly similar, showing that all of earth’s organisms share a common ancestry. The theory of evolution is a scientific theory that essentially states that species change over time there are many different ways species change, but most of them can be described by the idea of natural selection the theory of evolution through natural selection was the first scientific theory .
