Warm-Up: p27
5 pts
1. What is the purpose of overproduction?
2. Is the following statement true or false? Justify your answer:
According to Darwin’s theory of natural selection, individuals survive because
they acquire new characteristics during their lifetime.

h/w:
Select an organism (plant or animal)
You are going to be assigned an evolution project in the next couple classes.
You will need to trace the evolution of any organism you would like. Begin to
think about what organism you would select and see what info is available.
You will be expected to discuss its adaptations, nearest LIVING relative of a
different species, and it’s evolutionary history.
Homework answers
1. Lamarck believed an individual organism passed traits on to
its offspring. He could not support his ideas. Darwin
showed how traits could be passed on by natural selection.
2. Darwin noticed that beak shapes and sizes differed among
finches. This led him to believe the finches evolved
differently
3. Isolation stops populations from interbreeding so new
species evolve
4. The third species most likely evolved from one of the two
other species. Isolated by mountains, it began to develop its
own unique characteristics
5. White fur; it will help the hare blend in, escaping predators
8.L.4 Understand the evolution of organisms and
landforms based on evidence, theories and
processes that impact the earth over time.
8.L.4.1 Summarize the use of evidence drawn from
geology, fossils, and comparative anatomy to form
the basis for biological classification systems and
the theory of evolution
8.L.4.2 Explain the relationship between genetic
variation and an organism’s ability to adapt to its
environment
TLW explain the the relationship between
genetic variation, natural selection and
evolution in a quick write after watching a video,
completing video questions, and sorting finch
species using different traits.

1. How are genes and genetic variation related
to evolution? p29
2. Does Natural Selection work on an
organism’s genotype or phenotype? Explain
