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.
