This was a revolutionary advance in biological thinking on the sources and modes of selection driving evolutionary change.

WebIn fact, in the perspective of the Red Queen Hypothesis, life gains much autonomy from the physical environment since the latter is no longer needed to put evolution into motion. … The Red Queen hypothesis is a hypothesis in evolutionary biology proposed in 1973, that species must constantly adapt, evolve, and proliferate in order to survive while pitted against ever-evolving opposing species. The hypothesis was intended to explain the constant (age-independent) extinction probability … Zobraziť viac In 1973, Leigh Van Valen proposed the hypothesis as an "explanatory tangent" to explain the "law of extinction" known as "Van Valen's law", which states that the probability of extinction does not depend on the lifetime of … Zobraziť viac A competing evolutionary idea is the court jester hypothesis, which indicates that an arms race is not the driving force of evolution on a large scale, but rather it is abiotic factors.
