Meet DARWIN
Charles Darwin was the more sane of the two evolutionists :) Compared to Lamarck he makes things a little more common sense, right? Charles Darwin was a naturalist that spend a few years on the HMS Beagle.
Most of the time we hear about his studies on the Galapagos Islands
...where we noticed the lengths of the tortoises necks
and the different beaks on finches.
Darwin is best known for his theory of NATURAL SELECTION and for showing that all species of life have evolved over time from common ancestors. In 1859 he published his book "On the Origin of Species: by Means of Natural Selection"
Games to review for midterm
here's a site from another teacher that has links to all of our topics on the midterm...use these 'games' to help in reviewing...much more fun than reading your notes or the textbook, right :)

Meet LAMARCK
Jean-Baptiste Lamark was the "crazy" one! When thinking evolution he's the one who stated the Law of "Use or Disuse" (aka the Inheritance of Acquired Traits). Lamarck believed that whatever the parent 'gets' during their lifetime, then their children will also 'get' that as well.
In other words..if you became a body builder then you kid your be 'all muscles' too. Or if you lost a limb, then your child would be born without that limb too.
His most common example is the giraffe...he says that the giraffes necks got longer because they slowly "stretched" them out each generation and allowed their babies to be born with longer necks each time.
Remember that 'back in the day' of Lamarck they had NO IDEA of genes, DNA and all that cool stuff. They had yet to discover exactly why we looked like our parents and how our traits were passed along through the generations.

ahh...MUTANTS!!
MUTATIONS are simply just a change in the normal DNA sequence. Here's an awesome site that tells you ALL things about Mutations.
And here's some unusual mutations...
