Broadly speaking, OEC occupies a middle ground between young Earth creationism (YEC) and theistic evolution (TE). In contrast to YEC, it is typically more compatible with the scientific evidence on the issues of physics, chemistry, geology, and the age of the Earth.[1] But, like YEC and in contrast with TE, it rejects macroevolution, claiming it is biologically untenable and not supported by the fossil record,[2] and the concept of universal descent from a last universal common ancestor.
