Cards

Term
features of a divinely inspired creation
Definition
supreme being placed organism on Earth
Species do not change
Organisms look and function according to design made by supreme being
Term
Common descent
Definition
different modern organisms share same ancestors
Term
Transmutation of species
Definition
how one species can gradually change to another
Term
Binomial nomenclature
Definition
is a formal system of naming species of living things by giving each a name composed of two parts. deleted the multiple name of same species or same name of different species.
Term
Nested hierarchy of organisms
Definition
it was the kingdom, order, family, genus and species. Later on we added phylum and class. This hierarchy is absolutely critical for organizing species into groups by relatedness and decent.
Term
Sedimentation
Definition
sediments deposited by water were compressed to form stone
Term
Erosion
Definition
Rock exposed to the elements breaks down into sediment
Term
Gradualism
Definition
profound change is the cumulative product of slow but continuous processes
Term
Great Geological Cycle
Definition
Sedimentation: sediments deposited by water were compressed to form stone Erosion: Rock exposed to the elements breaks down into sediment
Term
"we find no vestige of a beginning, no prospect of an end"
Definition
James Hutton showing that the world has been here for a long time and there is no sight in the end.
Term
"invisible hand"
Definition
Term used by Adam Smith to describe the natural force that guides free market capitalism through competition for scarce resources.no regulation of any type would be needed to ensure that the mutually beneficial exchange of goods and services took place, since this "invisible hand
Term
Competition and self-interest
Definition
Importance of competition and self-motivation and thought it kept markets healthy and diverse. Less competitive sellers will not be able to succeed. Self-interest markets don’t benefit the society want to benefit themselves.
Term
Lamarckian evolution
Definition
Environmental force played a role to make organisms adapt to their environment used by characteristics passed on. Giraffes are known for JBL- an acquired trait during the lifetime, which would be passed on their offspring’s.
Term
Acquired traits
Definition
traits you gain over your lifetime and are not passed down (pierced ears)
Term
Populations grow geometrically, while food supplies only grow linearly
Definition
shows that over time that the amount of people will dramatically increase(like a parabola) and the food supply will increase a lot slower than the people
Term
The role of disasters in keeping the food supply in line with the population
Definition
what Thomas Malthus is saying is without disasters (like diseases that kill many) that food supply will run out and will cause a famine
Term
Impact of extinction on theories of creation
Definition
beforehand extincion was not seen as possible because God made every species perfect, now we know that there were species before humans.
Term
catastrophism
Definition
world made after huge catastrophe,
Term
"the present is the key to the past"
Definition
Idea that past processes should be reflected in the present day.
Term
Uniformitarianism
Definition
The processes that shape ancient geology are the same as those in modern times
Term
Darwin's observations on the voyage of the Beagle and their impact on his theory
Definition
showing different kinds of species (like the finches) finding fossils of extinct animals, finding out that some birds were prevalent on some of the islands but non-existint on the others.
Term
Wallace's Line
Definition
E landmass and the islands up to Bali must have must been connected to Asia, while Wombok and everything to the W must have been once been connected themselves. He thinks the ancient physical connection could explain the shared group of birds in the E and the groups of birds in the W. He is also correct the distance between Bali and Wombok is short but the ocean is deep because Bali is just over on the edge of the continental shelf and Wombak is just across it for millions of years due to continental drift these plays were much farther apart. Line that marks that division
Term
Greek philosopher Anaximander
Definition
* Common descent * Transmutation of species
Term
Carolus Linnaeus
Definition
* Tried to understand divine plan by seeking similarity among organisms * Binomial nomenclature * Hierarchical classification
Term
James Hutton
Definition
* Founder of modern geology * Natural processes shape rock formations
* Gradual change leads to massive change through time * First major western contradiction of young Earth hypothesis
Term
Adam Smith
Definition
* Laissez-faire economics * Chaos governed by invisible hand * The benefits of competition
Term
Jean-Baptiste Lamarck
Definition
* First truly complete theory of evolution * Environmental forces shape adaptation * Use and disuse
Term
Thomas Malthus
Definition
* An Essay on the Principle of Population * Populations grow geometrically, while food supplies grow linearly * Outside forces “rectify” this disparity
Term
Georges Cuiver
Definition
* Establishes comparative anatomy and paleontology
* Verifies that extinction occurs
* Proponent of “catastrophism”
Term
Charles Lyell
Definition
•The processes that shape ancient geology are the same as those in modern times (Uniformitarianism) * Steady accumulation of minute changes * Young Darwin’s reading material
Term
Charles Darwin
Definition
* Species evolve from common ancestors * Mechanism of evolution is natural selection
Term
Gregor Mendel
Definition
* Father of genetics * Traits are inherited by predictable laws
Term
James Watson and Francis Crick
Definition
* Discovered structure of DNA * Means for heritable information to be stored and passed on
Term
Glyptodon
Definition
cannot explain extinction with modern sea shells near by, proved catastrophicism did not happened, showed it was related to modern armadillos
Term
The importance WHERE the organisms came
Definition
meaning many locals could tell just by a certain type of organism what island it came from showing that there was adaptations throughout all the islands.
Term
BIG IDEA
Definition
As many more individuals of each species are born than can possibly survive; and as, consequently, there is a frequently recurring struggle for existence, it follows that any being, if it vary however slightly in any manner profitable to itself, under the complex and sometimes varying conditions of life, will have a better chance of surviving, and thus be naturally selected.
