The scientific method |
Hypothesis, Observation, Data experiment. Hypotheis is Reject or Support findings. Science defines probabilities not truth. |
|
Definition of evolution |
Evolutionis a change in allele frequecncies within a population over multiplegenerations. |
|
Natural vs. artificial selection |
· No individual is exactly the same, some will be better adapted for specific survival Vs. Selective breading has occurred for hundreads of years (pigions) |
|
Comte de Buffon |
· Mamal communities in similar, but geographically isolated environmentsare not the same. Thus they must have changed after leaving ancestral homeland Natural historian |
|
Thomas Huxley |
Darwin's Bulldog Famous 1860 oxford debate with Willbeforce English Biologist |
|
Alfred Wallace |
· Alfred admired Darwin and came up with same ideaas Darwin and Wallace came from nothing and worked up the latter of academia Darwin coathored a work with him |
|
Charles Lyell |
Principles of Geology -Uniformintarianism: This idea states that observing things today can give an idea on how things formed in the past. -Gradualism: little things over time makes the rocks -Darwin took this book on Voyage of the begal
|
|
Georges Cuvier |
Closely studied fossils Catastrophism Natural process of things going extinct formthings like volcanos and in the biblical scence the great flood |
|
Adam Sedgwick |
Mentored Darwin at Cambridge specificaly in geolgy would never accept his thoery of natual selection though |
|
John Henslow |
Mentored Darwin at cambridge got him the opertunity to travel on the begal and thus find natural selection |
|
James Ussher |
From the bible he concluded Earth was created on Oct 23 4004 BC Was very difficult to prove this date wrong |
|
William Herschel |
created a Cosmic Evolution Deep time nebular theory based on physics. |
|
Copernicus |
Sun rather than the earth at the center of the universe was a mathmatiction and astronomer. |
|
Galileo |
Father of modern science was a proponent of heleocentricism rather then goecentricism, and was atacked by the church becase of this. |
|
Thomas Hunt |
One of the discovers of chromosms though more developed microscopes and frute flys |
|
Nicolar Steno |
Law of superposition -Layers of sediment the farther down an objectfound the older the object is -Short term studies like 10 year study show howlong it takes to put down a layer of sediment |
|
James Hutton |
Deep time -Uniformitartianism ----No vestige of beginging no prospect of an end ----Geological process continue indiscrimintlyforever |
|
Jean- Baptiste Lamarck |
Animals evolve because of enviornmental forces intheir life time Geraffs strech for food aka long neck First person to formulate amechanism for how things change (evolve) neo Lamarckism= epi genetics (exp if as a female you go undernutriticla distress under pubertiy your babys will be lower birth rate) |
|
The voyage of The Beagle |
Voyage Darwin undertook around south America, stped at the galapogose islands was observing animals and plant life on voyage collectiong samples, 5 year voyage crew liked him becase he would talk to them so they collected samples as well |
|
Allopatric speciation |
Species getting geographicaly isolated Then when ocean seperates the species speciesadapt, small mamoths (pigmy hourses iceland) |
|
Mendelian traits |
Monogenic traits only deteramend by one gene on or off like a widows peak |
|
Monophyletic and paraphyletic groups |
mono: a common ancestor and all of its descendant Para: a commonon ancestor with out all of it's descendants (Dinorsors would need to include birds) |
|
Cyclops |
Mamoth Skulls beliled to the cyclopse becase of their single eye cavity |
|
Structure and composition of DNA |
Double Helix, Deioxy- ribose neuclaic Acid Rosalind Franlkin X-ray actual shape discovery credited to Watson and Crick though Adenine- Thymine Guanine- Cytosine |
|
Eldredge and Gould |
punctuated equilibrium climate change = quickevolution |
|
Cell division |
Mitosis and Meiosis Mit: duplication of somatic cells meiosis: duplication of haploid cells Sex cells |
|
Ideas that Darwin relied on for his theory |
1.You must have deep time 2.You must have intra specific variation (withinspecies) 3.You must have natural “checks” on population 4.Traits must be passed to offspring |
|
Deep time |
Earth is 4.5 billion years old and the concept that the earth is old |
|
Biological and morphological species concepts |
Bio: If you can have babies together Mor: How they look |
|
Homologous vs. Analogous traits |
Homo: traits that are prent from our ancestors aka ahumurs Ana: Traits that don’t represt evolutionaryrelationships (Batt Wings)
|
|
Origin of Species |
Publihsed 1859 it was a best seller, didt have a mechanism for inheritance only real flaw, darwin sugest in it Pangenisis or blending of parent traits. |
|
The rules of taxonomy |
Linnaeus: created modern taxonomy, which is a method for catergorizing the biological world. Kingdom, phylum, class, order, family, Genus Species. |
|
The discoverers of the double helix structure of DNA |
James Watson and Francis Crick, Maurice Wilkins Credited with discovering DNA Rosalind Franklin Worked the X-Rays and died before the Nobelprize was awarded. |
|
The “forces of evolution” |
Random Mutation, Genetic Drift Non- Random Gen Flow (sex), Natural Selection |
|
Genotype vs. Phenotype |
Geno= fixed at conception*· Pheno= The physical expression of the genotype -----------(Natural selection acts on an organism’sphenotype) |
|
Jefferson and the Moose |
Jeferson was in diologue with buffon to show him that species in North america were not degerations or less then those of europe that in fact they were stonger and more abondant. He sent buffon a moose carcuse that was meant ot prove thisn fact and creideted the size of north american bears and beavers in comparison to europes smaller versons |
|
The Scala Naturae |
The great chain of being clasification of all living beings on god's earth, God on top then humans then less and less important or evoloved species. |
|
Scientific hypotheses, theories, and laws |
Hypotheses: is a testable question that can be rejected or supported though experiment and data colleting Theroy: is a hypothesis who is continualy supported bydata every time the hypothesis is tested. (Systems and how they work)
Law: Same thing just usualy has to do with something mathmaticaly able to explain the hypothesis |
|
Microevolution vs. macroevolution |
Macroevolution:refers to large scale evolutionary change over long periods of time. Microevolution:refers to changes in allele frequencies within a species. |
|
Darwin’s finches |
Finches on the islands of the Galapogose depindent on what they eat thier beake and body size idffers giving them inherint advantages to survive, based on sesinal changes in food suply. Didnt even notice them while their. |
