    Biological evolution is DEFINED as a change in allele frequencies in a population of organisms over time. 

    That's it.  No more, no less.  That is the basic observation that is termed, "evolution."  Natural selection is thought to be the primary mechanism whereby evolution occurs.

      Distinctions between micro and macro-evolution are emphasized ONLY by creationists.  It's part of their own "evolution"-- once they realized they could no longer deny evolution as a whole, they had to do something to "preserve" their sciency pretensions.

    The process by which living species remain well adapted to an ever-changing environment, through the process of natural selection.

    There's 2 definitions of evolution:-

    1. the gradual development of something, synonyms including growth, advancement and change.

    2. the process in which different living organisms are believed to have developed from earlier forms in the earth. For example, humans are believed to be evolved from primate animals (apes, monkeys, lemurs and gorillas), and different birds have developed different beak shapes to get to different sources of food, like nuts, flower pollen, grubs, berries and insects.

    Hope this helps.

    Gradual change over time.

      Actually it's just "change over time" for the most basic definition.

    Within the field of Population Genetics evolution is DEFINED as a change in allele frequencies in a population of organisms over time. However this is not a definition of the Theory of Evolution and other evolutionists say this is microevolution. (https://evolution.berkeley.edu/evolibrary/article/...

     .

    The Theory of Evolution can be defined as “Life on earth evolved gradually beginning with one primitive life form – perhaps a self-replicating molecule – that lived more than 3.5 billion years ago; it then branched out over time, throwing off many new and diverse species; and the mechanism for most (but not all) of evolutionary change is natural selection. ”  

    ― Jerry A. Coyne, Why Evolution Is True

     .

    Or more succinctly "... all the living forms in the world have arisen from a single source which itself came from an inorganic form. This theory can be called the ‘General Theory of Evolution’ and the evidence that supports it is not sufficiently strong to allow us to consider it as anything more than a working hypothesis.

      cosmo, if you had taken a few seconds to do a search you would have found "Gerald Allan Kerkut (or G. A. Kerkut) (19 August 1927 – 6 March 2004) was a noted British zoologist and physiologist."

    I guess that evolution can be defined as the natural selection.

      a change in allele frequencies in a population of organisms over time produces adaptation

    I can’t believe in evolution because it doesn’t exist.

    Adaptation to environment never changes one animal into another. Fish eggs are still fish eggs and chicken eggs are still chicken eggs. 

    Wanna see “evolution”? 

    God can raise children for Abraham from the stones if He likes. He doesn’t need any of us.

      But that is exactly what evolutionists claim. They just add a few intermediate steps.
