Lecture 2: Evolutionary Theory  Current News  New species of monkey!!  Found in the Dem Rep of Congo  Circapithecus circamiensis (spelling?!?!) “Lesula”  First new monkey species found in Africa in 23 (?) years  Last Class  4 Subfields of Anthro  Arch, Cultural/Soc, Linguistic, and Physical/Bio  This class: Evolutionary Theory  Common misconceptions  Evolution is “only a theory”  Evolution IS a theory, but this statement generally implied that Evolution is just a thought and has no data that can support it  Term “theory” is often misused or deliberately distorted  Theory: something that can be tested multiple times and can’t be disproven.  A hypothesis only becomes a theory when it’s tested multiple times and has never been disproven  Humans “evolved” form monkeys  “If humans evolved from monkeys, why are there still monkeys?”  We didn’t evolve from monkeys or apes as we know them today  Humans share a common ancestor with chimpanzees 6-8 million years ago  Human lineage diverged from monkeys 20 million years ago  Evolved along different evolutionary paths  Apes: chimps, orangutans, chimps, gorillas.  Monkeys: baboons, lesulas, etc.  Evolution is a linear trend towards complexity  Evolution does not move from simple to complex  This implies the idea that humans are the most important or most evolved  This derives from the “Great Chain of Being” presented by Aristotle in 384-322 BCE which implies stasis and immutability. It orders from least perfect beings to most perfect beings  Think of evolution more like a bush than a tree  Evolution defined  Change in the genetic structure of a population  Evolution works via natural selection  History of Evolutionary Thought  Belief during middle ages (in Europe): universe is static  Fixity of species  Argument from design  Plan of universe = God’s design  James Ussher 1581-1656  Analysed Genesis and discovered that the Earth was created on Oct 23, 4004 BC  William Paley 1802  Looked at the human eye and used it as an argument for the existence of God  Where there is design, there must be a form of designer  BUT! What we know today about the human eye  They are great examples of adaptation  Light enters through a transparent opening and passes through a diaphragm called the iris. The iris controls how much light is allowed to pass into the eye  The light then passes onto a lense that projects the image onto the retina.  Because light acts differently in water and in the air, fish and humans have differently shaped lenses that have evolved and adapted to the lights’ different properties.  The scientific revolution  Exploration and discovery 15 century  Once people started to travel the globe, they were exposed to different species and environment.  Change exists on Earth  Earthquakes, volcanoes, fossils  Precursors to the theory of evolution  Astronomy  Copernicus (1500’s) challenged the idea that the Earth is at the centre of the universe  Earth is NOT the centre of the universe  Heliocentric (Sun in the centre of the universe)  Galileo (1600’s) reinforced Copernicus’ theory through mathematic data  Logic and mathematics to support Copernicus  Telescope, first empirical approach to science th  John Ray (17 century) first to develop the concept of species  Organisms reproductively isolated  Biological definition of species  Genus and species  He recognised that certain species had similarities to other species and grouped them together into a larger group called a genus  Carolus Linnaeus (1701-1778)  Systema Naturae 1735  Binomial nomenclature  Homo sapiens OR Homo sapiens  Species must be either italicised or underlined  The first word must be capitalised but the second shouldn’t be  Taxonomy  Added class and order to taxonomy  So: Class  Genus  Order Species  Included humans in his classification (
