They help in that, many recently discovered fossils form series that trace the evolution of modern species from extinct ancestors. Patterns in the distribution of living and fossil species tell us how modern organisms evolved from their ancestors. Evolutionary theory explains the existence of homologous structures adapted to different purposes as a result of descent with modification from a common ancestor.

Oxygen debt is a physiological phenomenon in which a person consume oxygen at fater rate that it replaced by new oxygen molecules.
