 | | Most scientists interpret this to mean all existing organisms share a common ancestor, which had already developed the most fundamental cellular processes, but there is no scientific consensus on the relationship of the three domains of life (Archaea, Bacteria, Eukaryota) or the origin of life. |
 | | A theory is an attempt to identify and describe relationships between phenomena or things, and generates falsifiable predictions which can be tested through controlled experiments, or empirical observation. |
 | | So, for scientists "theory" and "fact" do not stand in opposition, but rather exist in a reciprocal relationship; for example, it is a "fact" that an apple will fall to the ground if it becomes dislodged from a branch and the "theory" which explains this is the current theory of gravitation. |
