Sister taxa: ?
Polytomies represent uncertainty about phylogenetic relationships
Monophyly vs paraphyly
Rooted and unrooted trees

No full indication of time direct
Lecture #2 Evo-devo
Commonality in body plans in all animals on earth!
HOX genes of the fly and mouse
Look at the similarity
between drosophila and a
vertebrate and the HOX
genes. Different names but
homologous. The different
HOX genes control different
Lecture #7: Evidence of evolution
Artificial selection &
History is written all
over us: Vestiges,
Embryos and Bad Design
What is the difference between natural and artificial selection?
How were dogs initially domesticated? How did dogs evolve so many
Lecture #6 The
How can gene duplication provide an
A: the duplicated gene can now do double the
work and it allows for a new function
What are the 4 categories of evidence for evolution?
How does the fossil record provide
How developmental mutations can lead to new
-Knowing the developmental ancestry of every
- Rubber Stretching
Every embryo starts as a single cell
Division and differentiation create many
Evolution in Finite
frequency changes in
small populations not
due to natural selection!
What is genetic (random) drift?
How does population size contribute to genetic drift?
What are the effects of genetic drift on differen

But if it makes any difference to you, I do.
The importance of development in
evolution: The HOX genes
How can developmental genes control the morphology of the chicken and duck foot?
How is this evolution?
And then came Darwin.
Lecture #3 Bio 2P05
Potential exam questions:
1.What was Darwins definition of evolution?
2.What are the 3 components of evolution by natural selection?
3.Why did Darwin have a problem defining inheritance as a component
BIOL 2P05 (#1)
Dr. M.J. Bidochka
Potential exam questions:
1.What are 6 changes in human perception that has allowed the acceptance
of evolution in the last 100 hundred years?
2.What is Platos allegory o
Darwin: the process of decent with change (modifications) that is responsible for origin, diversity
and maintenance of life
Nasa: the result of changes in the genetic content (mostly allele frequencies but not only) in a
population over tim

Lectures 8 & 9
What is the Hardy-Weinberg equilibrium?
Perform problems on HWE. Start with different p and q and
determine what the genotype frequencies should be.
Why wouldnt a population be in HWE?
How would you test for HWE?
