In 1825 Darwin enrolled in medical school at the University of Edinburgh, he gave up his studies without completing the course. Drawing paid lessons in taxidermy from John Edmonstone. Then, he went to Cambridge University to study theology.  Darwin’s voyage of Discovery In no rush to take holy orders, in 1831 Darwin accepted an offer to embark on a five-year voyage aboard HMS Beagle. Where he…. ➔ Explored remote regions and marvelled at a world so different from the one he knew. ➔ Encountered birds with bright blue feet, sharks with T-shaped heads and giant tortoises. ➔ Collected plants, animals and fossils, and took copious field notes. These collections and records provided the evidence he needed to develop his remarkable theory. Sources  Darwin’s voyage of Discovery Interesting facts In a single day’s trip into Brazilian forest, he collected 68 species of beetles.  I. Patterns of Biodiversity 1. Animal species inhabited separated, but ecologically similar habitat around the globe. 2. Animal species often occupied different habitats within a local area. 3. Some fossils of extinct animals were similar living species  WARM - UP ACTIVITY Challenge yourself with this rapid review II. Ideas that shaped Darwin’s thinking II.

Ideas that shaped Darwin’s thinking The forgotten father of Evolution Alfred Russel Wallace (1823-1913) was a man of many talents - an explorer, collector, naturalist, geographer, anthropologist and political commentator. In 1858 he wrote to Darwin, speculating on evolution by natural selection bases on his studies of the distribution of plants and Animal (Biogeography).  Visual Thinking Look at the teeth in the lion's mouth.

Artificial Exit Question: How does natural variation affect Evolution? selection  Evidence of Evolution Organisms have changed over time? A. Fossil Record 1. Fossil evidence a. Fossil – the preserved remains of an organism. Forms imprints/molds in rock and mud. b. Radioactive dating - Use radioactive isotopes to determine age - decay rate of carbon-14 used to date young fossils Paleontologist – studies fossils Geologist – uses fossils to explain earth’s history Anthropologist – studies human evolution ❖ Important Note about the fossil record: 🡪 the fossil record is incomplete 1. Many species lived in unfavorable environments that do not allow for fossil formation Ex. Grasslands, mountains, deserts 2. Even though it is incomplete, the fossil record still presents us w/ strong evidence of evolution Evidence of Evolution Organisms have changed over time? B.

C. Body structure Latin for "agreeing," a. Homologous structures – Diff. organisms have body parts w/ similar structure, but diff. fxn (suggests a common ancestry)  Evidence of Evolution Organisms have changed over time? C. Body structure b. Analogous structures – Diff. organisms have body parts with a similar fxn, but not structure. Insect wing Bat wing Bird wing  Evidence of Evolution Organisms have changed over time? C. Body structure i a l t i g es e s ur. V ct C Stru body parts are reduced in size and appear to have no fxn (e.g. appendix, human tail bone, snake legs) Evidence of Evolution Organisms have changed over time? D.

Clade – a group of species that includes a single common ancestor and ALL descendents of that ancestor 1. A common ancestor of species E and C? 2. What two species are most closely related? a) A and B c) C and D b) B and C d) E and A 3.
