Biology is the science discipline that studies life processes or characteristics of living organisms, including their structure, function, growth, origin, distribution and evolution. The word Biology comes from the Greek word bios meaning "life", and logy which basically means "the study of".
Creation biology is basically the study of biological systems under the inference that God created life on Earth as described in Genesis. As the theory of evolution is found as an integral part of all secular biology fields, it is critical that creationists have a thorough understanding of biology.
Creation biology is premised on the idea that God created a finite number of discrete created kinds or baramin. While these forms of life have the ability to vary, and even undergo speciation, they cannot arise spontaneously from non-life, cannot interbreed outside of their kind, and cannot increase in genetic complexity.
