Objections to evolutionObjections to evolution have been raised since evolutionary ideas came to prominence in the 19th century. When Charles Darwin published his 1859 book On the Origin of Species, his theory of evolution (the idea that species arose through descent with modification from a single common ancestor in a process driven by natural selection) initially met opposition from scientists with different theories, but eventually came to receive overwhelming acceptance in the scientific community.
Flood geologyFlood geology (also creation geology or diluvial geology) is a pseudoscientific attempt to interpret and reconcile geological features of the Earth in accordance with a literal belief in the Genesis flood narrative, the flood myth in the Hebrew Bible. In the early 19th century, diluvial geologists hypothesized that specific surface features provided evidence of a worldwide flood which had followed earlier geological eras; after further investigation they agreed that these features resulted from local floods or from glaciers.
Old Earth creationismOld Earth creationism (OEC) is an umbrella of theological views encompassing certain varieties of creationism which may or can include day-age creationism, gap creationism, progressive creationism, and sometimes theistic evolutionism. Broadly speaking, OEC usually 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 consensus on the issues of physics, chemistry, geology, and the age of the Earth.
MicroevolutionMicroevolution is the change in allele frequencies that occurs over time within a population. This change is due to four different processes: mutation, selection (natural and artificial), gene flow and genetic drift. This change happens over a relatively short (in evolutionary terms) amount of time compared to the changes termed macroevolution. Population genetics is the branch of biology that provides the mathematical structure for the study of the process of microevolution.
Young Earth creationismYoung Earth creationism (YEC) is a form of creationism which holds as a central tenet that the Earth and its lifeforms were created by supernatural acts of the Abrahamic God between approximately 6,000 and 10,000 years ago. In its most widespread version, YEC is based on the religious belief in the inerrancy of certain literal interpretations of the Book of Genesis. Its primary adherents are Christians and Jews who believe that God created the Earth in six literal days.
