[Answer] What is the only evolutionary mechanism that consistently leads to adaptive evolution?

Answer: natural selection
What is the only evolutionary mechanism that consistently leads to adaptive evolution?

Adaptive evolution results from the propagation of advantageous mutations through positive selection. This is the modern synthesis of the process which Darwin and Wallaceoriginally identified as the mechanism of evolution. However in the last half century there has been considerable debate as to whether evolutionary changes at the molecular level are largely driven by natural selection or random genetic drift. Unsurprisingly the forces which drive evolutionary changes in our own species’ lineage have been of p…

Evolutionary invasion analysis also known as adaptive dynamics is a set of mathematical modeling techniques that use differential equations to study the long-term evolution of traits in asexually reproducing populations. It rests on the following four assumptions about mutation and natural selection in the population under study: Individuals reproduce clonally. Mutations are infrequent and natural selection acts quickly. The population can be assumed to be at equilibrium when a new mutant …

In biology adaptation has three related meanings. Firstly it is the dynamic evolutionary process that fits organisms to their environment enhancing their evolutionary fitness. Secondly it is a state reached by the population during that process. Thirdly it is a phenotypic trait or adaptive trait with a functional role in each individual organism that is maintained and has evolved through natural selection. Historically adaptation has been described from the time of the ancient Greek philosophers such as Em…

Modern evolutionary psychology however is possible only because of advances in evolutionary theory in the 20th century. Evolutionary psychologists say that natural selection has provided humans with many psychological adaptations in much the same way that it generated humans’ anatomical and physiological adaptations.
