It is possible that we are facing the end of the effective life of most of available antibiotics. [56] Predicting the evolution and evolvability [57] of our pathogens, and devising strategies to slow or circumvent the development of resistance, demands deeper knowledge of the complex forces driving evolution at the molecular level.

Conscious evolution – Hypothetical ability of the human species to choose what they will become; Ecology and Evolutionary Biology – Interdisciplinary field of study; Effective evolutionary time – Hypothesis offering a causal explanation of diversity gradients
Devolution, de-evolution, or backward evolution (not to be confused with dysgenics) is the notion that species can revert to supposedly more primitive forms over time. The concept relates to the idea that evolution has a divine purpose ( teleology ) and is thus progressive ( orthogenesis ), for example that feet might be better than hooves , or ...
Alternatives to Darwinian evolution have been proposed by scholars investigating biology to explain signs of evolution and the relatedness of different groups of living things. The alternatives in question do not deny that evolutionary changes over time are the origin of the diversity of life, nor that the organisms alive today share a common ...
The result of four billion years of evolution is the diversity of life around us, with an estimated 1.75 million different species in existence today. [71] [72] Usually the process of speciation is slow, occurring over very long time spans; thus direct observations within human life-spans are rare.
Brian Hall traces the roots of evolutionary developmental biology in his 2012 paper on its past present and future. He begins with Darwinian evolution and Mendel's genetics, noting the tendency of the followers of both men in the early 20th century to follow separate paths and to set aside and ignore apparently inexplicable problems.

No evolution Larvitar Yōgirasu (ヨーギラス) Rock / Ground — Pupitar (#247) In the series' lore, Larvitar are born deep underground and consume dirt for sustenance. A Larvitar appears in the Pokémon anime, where it acts as a major cast member for several episodes.
In humans, the vermiform appendix is sometimes called a vestigial structure as it has lost much of its ancestral digestive function.. Vestigiality is the retention, during the process of evolution, of genetically determined structures or attributes that have lost some or all of the ancestral function in a given species. [1]
