Carbon 14 background

Hey gang,

Here's a good site for a review of carbon dating.  Please read the first two pages on intro and how C-14 is made.  We will go over half life info tomorrow.

Class,
Today's homework is to please read the panelists' statements RE antibitic resistance at the evolution website.  See you tomorrow.

Evolutionary arms race

Hello class.  I hope you enjoyed the video.  Please be able to explain the following evolutionary relationships:

poisonous newts in oregon and ________

russian prisoners and TB (tuberculossi) 

Humans and the more mild form of cholera

Humans and HIV , big cats and FIV

Leafcutter ants and __________

the waxy body coating of leafcutter ants and ant diseases 

Humans and large animals (stable animals)  --as an aside, this is part of the reason I decided to get a family dog.

Natural selection game

Class,

Give this game a try.  Note how there are always events that happen over time for which evolution cannot prepare a population.  Good luck (it took me three tries before I got it).
