Basic Forces (what is needed for an evolvable system). Evolution – Basic Forces. Self-replication - reproduction. Heritability - a system by which characteristics can be passed from one generation to the next (here on Earth, DNA is that system). . Theistic Evolution.

God must be the creator of the universe. 3 views Christians can faithfully hold: Old-Earth Creationism, Young-Earth Creationism, Theistic Evolution. Mechanisms of concerted evolution. Unequal cross-over. Gene conversion: non-reciprocal transfer of information between homologous sequences; the main mechanism invoked to explain concerted evolution. Chapter Overview Questions. How do scientists account for the development of life on earth?. What is biological evolution by natural selection, and how can it account for the current diversity of organisms on the earth?. Although many factors and processes are involved in the process of this evolution there are three important ‘macro-patterns’:. War and Militarism,. The emergence of capitalism, and.
