Slide 1 - Tekstslide
Evolution has to do with ..
Slide 2 - Woordweb
Evolution is about...
The emergence of new species (all organisms)
The way in which these species arise
Determining which species are related to each other
Slide 3 - Tekstslide
Evolution is
NOT
about ..
How life came to be
How the universe/solar system/earth/etc. came to be
If God exist
Slide 4 - Tekstslide
3 main mechanisms
Evolution can be summarized into these 3 mechanisms:
Variation in genotypes
Natural selection
New species arise
Slide 5 - Tekstslide
Variation in genotypes
Sexual reproduction > new/different genotypes
New genotypes > new/differnet phenotypes
Lot's of changes in genotype > DNA changes 'too' much > new species
Slide 6 - Tekstslide
Slide 7 - Video
Natural selection
Species who have adapted to
their environment will survive
and reproduce
'Good' genes are passed on
'Bad' genes dissapear
Slide 8 - Tekstslide
New species arise
Animals of same species are split up
The environment slowly changes.
Because of natural selection, other genes are 'good' in new environment
Species have become different species after many years of evolution, due to living apart
more examples
Slide 9 - Tekstslide
New species arise
New species arise due to
LONG
periods of evolution in a species
Many small changes together become big changes
Evolution takes very long! (thousands of years)
Slide 10 - Tekstslide
What is the deciding 'thing' that tells you that two organisms belong to the same species?
Slide 11 - Open vraag
