Galapagos Islands Darwin saw variation (difference) within species on the different Islands Lonesome George • Last known individual of one of 11 subspecies; three have already died out • “Rarest creature” in the world • 60-90 years of age Darwin’s Finches Different finches lived in different environments Darwin’s Finches The finches had different beaks What did his observations mean? Darwin’s Finches If you were a finch who had to eat BIG seeds, which beak would be best? Darwin’s Finches If you were a finch who had to eat SMALL seeds, which beak would be best? Darwin’s Finches Finches beaks matched their environment Darwin used his observations to develop the theory of evolution EVOLUTION: change over time What makes you different from a chimpanzee? Evolution of Intelligence? Research by Matsuzawa et al. Ayumu and short-term memory Ayumu averages 80% accuracy with 9-digit strin Humans average 40% with 5-digit strings Try it yourself: http://games.lumosity.com/chimp.html What is Intelligence? Behavioral flexibility Insight and problem solving Calculation Memory Social awareness and skill Language Culture and learning In order for evolution to happen, you need…. V S I T Variation Selection Inheritance Time Stands for… Variation S I T Means… Difference between individuals Stands for… V Selection I T Means… Individuals with “good” traits will survive and reproduce more Stands for… V S Inheritance T Means… Genes are passed from parent to child Stands for… V S I Time Means… MANY generations Think: What part of VSIT is this? many generations differences between individuals individuals with good traits survive longer and reproduce more genes are passed from parent to child 5 thousand years A child gets his parents genes for brown eyes different kinds of beaks A butterfly who can camouflage to its environment survives longer Selection Selection Without looking at your notes, what 4 things do you need for evolution to happen? S = Selection Natural selection: organisms best suited to their environment as a result of good genes survive and reproduce Selection Natural selection = selection by nature Natural selection = nature (NOT a human) decides who survives. Think: Natural selection or not? A dog breeder chooses to mate only big dogs: Think: Natural selection or not? Birds with a big beak are more likely to survive and reproduce on a certain island: Think: Natural selection or not? Primates who are smarter are more likely to have children: Think: Natural selection or not? A farmer only allows his cows with dark fur to mate: I = Inheritance •Inheritance = genes are passed down from one generation to the next •Traits that you acquire (get during your life) are NOT inherited. EX: if you dye your hair purple, your kids will NOT have purple hair! Think: Inheritance or Think: Inheritance or not? not? A mother passes her brown eyes to her son: Think: Inheritance or not? A man who cuts his hair short has a child who also cuts his hair short: EXIT TICKET EXIT TICKET ilently and on your own, answer the questions below 1.
