    apply the evolution theory 
    the three steps: copy and fill in the gaps 
    1. V------- in in------ble t----s in a population
    2. The more s------- the individual is the longer it s-------, resulting in more opp----ties for r-------- and more o------- (=differential reproduction)
    3. As a result the m------ of off------- in a population will have inherited the su-----l t----s, or all---, which help them to f--- in the e------m. And so a population is a------- to its e------nt

    natural selection: a mechanism for evolution that is the result of d------l r--------n, v------n and h------y
    artificial selection: b------g selected organisms with s------c characteristics, in order to obtain offspring with d------d characteristics

    what happens to populations when the best-f.........g in..................s in that p................n keep passing their g...........s on to the next g....................s over time, so that the s..............s as a whole c.............s, and s................s
    STRUCTURAL: evolutionary changes in b.......... p............
    PHYSIOLOGICAL: evolutionary changes in the c...............l processes inside the c......... of an organism

    Slide 8 - Slide

    How can variety within populations lead to the evolution of different species?

    Slide 9 - Open question

    Use and disuse – Individuals lose characteristics they do not require (or use) and develop characteristics that are useful.
    Inheritance of acquired traits – Individuals inherit the traits their ancestors acquired during their lifetimes.

    Examples of what is traditionally called “Lamarckism” would include:
    - Giraffes stretching their necks to reach leaves high in trees (especially Acacias), strengthen and gradually lengthen their necks. These giraffes have offspring with slightly longer necks (also known as “soft inheritance”).

    - A blacksmith, through his work, strengthens the muscles in his arms. His sons will have similar muscular development when they mature.

    what is the best definition of fossil?
    fossils are preserved remains of once living organisms.
    fossils are petrified remains, or traces, of organisms or part of organisms from the past.
    fossils are any preserved remains, impression, or trace of any once-living thing from a past geological age
    fossils are the preserved remains or traces of organisms (plants, animals, etc) that lived in the distant past
