BIO120 Lecture 1
Approaches used in evolutionary biology:
Observational is natural history
Verbal model turned into graphical model(linear or curved) is theoretical
Comparitive- do’t do ase studies of  speies, do a geeral ealuatio of speies. (collect the same
data for many species_
Experimental microbes are the best molecule to study evolution on. Microevolution is key for
experimental
Important assumptions:
Biodiversity and adaption are key to evolution
Biodiversity and Adaptation:
Biodiversity arises from genetic variation
Evolutionary biology today:
Microevolution-testing theoretical models of how we expect organisms to operate in the wild. Very
experimental. Mechanisms
Macroevolution- historical. Trying to interpret the past to understand the present.
Water hyacinth- enormous capability of growing/cloning. Its flowers are very attractive to special long
tongue bees in the tropics. 3 forms, Darwin & Haldane assumed the third form went extinct. L and M
were still alive, S went extinct. Prof foud the issig for.  fors ere take  huas to the e

Babiana ringens rats tail: member of the iris family. Called the rats tail.
Primary feeding strategies: birds differ from the old and new world.

BIO120 Lecture 1 Revision
Chek y grades for la iforatio.
Slide 6:
Theory-verbal is saying what you think is occurring.
Graphical plot one parameter against the other, is the relationship linear or parabolic.
Mathamatical- make parameters that we estimate
Comparative-generality
Slide 10:
Toe central unifying concept of biology, and it effects many other disciplines aswell
Slide 12:
Macroevolution is largely pattern based and interpreting those patterns and interpreting what
happened to those patterns.
Slide 19:
Dari ifreeed that there should e 3 fors. Haldae ould’t fid the 3rd form. It was
assumed to go extinct.
Left chart: fertility of external species
Right chart: Inbreeding/self fertilization
Lecture 2 Revision:
Slide 5:
A phenomena with no purpose, evolution has no purpose. There is no way to stop evolution.
When evolution stops, life will stop.
Slide 7:
Every microorganism thru time is going to become a complex organism. Lamarcks view went
from simplicity to complexity. Darwin came up with the first tree branching view.
Slide 12:
Dari ae ak fro the eagle ad deoted the rest of his life to siee. Wallae ould’t
fund his expedition with Darwin, so he collected specimens around the world and sold them in
London for money.
