Macro-evolution – Refers to the emergence of major innovations or the unguided development of new structures(like wings) new organs(like lungs), and body plans(like the origin of insects and birds). It includes changes above the species level.
Micro-evolution – Refers to minor variations that occur in populations over time. Examples include variation in moth coloration and finch beaks, and the emergence of different breeds of dogs.
Darwinism – The belief that undirected mechanistic processes(primary random mutation and natural selection) can account for all the diverse and complex living organisms that exist. Insists that there is no long range plan or purpose in the history of life(ie.,that changes happen without intent)
Creationism – the theory that God’s creation occurred directly and not through Darwinian mechanism of evolution. Young earth creationist believe that all the earth is no more than 10,000 years old, and that all biological life forms were created in six calendar days and have remained relatively stable throughout their existence, while Old earth creationist claiming it to be more than 5 billion years.
Intelligent Design – The belief that earth and biological life owe their existence to a purposeful, intelligent creator.
