Term
In Essentialism
Definition
Variation is accidental imperfection
Term
Carolus Linnaeus
Definition
established framework of of modern classification
Term
Lamarkism
Definition
The more an organism uses a muscle, the bigger it gets
Term
Darwin's theory that all living things come from one or a few common ancestors and acquired new traits over time
Definition
Descent with modification
Term
Natural selection is also known as
Definition
Casual agents of change
Term
Evolution
Definition
The idea that organisms change over time to better survive
Term
Common descent
Definition
All species come from one common ancestor and we can all be put on a big family tree
Term
Gradualism
Definition
Adaptation in animals happen in small steps
Term
Population change
Definition
Evolution occurs by changes in it's proportion of individuals within a population
Term
natural selection
Definition
an organism is able to better survive because of an adaptation
Term
Blending inheritance
Definition
Variation should decrease not increase
Term
particulate inheritance
Definition
fluids are passed unaltered from generation to generation
Term
Neo Lamarkism
Definition
States that modifications might have been due to the direct effect of the environment on development

i.e plants getting thicker leaves in hot conditions
Term
Orthogenesis
Definition
Organisms evolve towards a predetermined end goal
Term
Modern synthesis
Definition
mutation and natural selection together cause adaptive evolution. Mutation is not an alternative to natural seletion but it's raw material
Term
Evolutionary change is
Definition
A populational process
Term
Speciation
Definition
the origin of two or more species from a common ancestor
Term
The two theories of Origin of Species
Definition
All Organisms descended with modification

Natural selection is the chief agent in modification
Term
adaptation
Definition
adaption is a feauture found in a population that gives an organism a better chance of suruviving
Term
Creationalism
Definition
Opposes the teaching of evolution and says it poses the belief that there is no god
Term
Descent with modification
Definition
All organisms descended from one or a couple ancestors and gradually acquired traits along the way
Term
Biological evolution
Definition
Change through genetic variation or gene frequency
Term
organic evolution
Definition
the sequence of events involved in evolutionary development
Term
modern or evolutionary synthesis
Definition
mutation and natural selection together cause adaptive evolution/ mutation is not an alternative to natural selection
Term
hypothesis
Definition
informed conjecture or statement
Term
macroevolution
Definition
Looking at the longterm features of evolution
Term
microevolution
Definition
account for origin of new species
Term
They used to use Triclisand
Definition
To kill all microbes
Term
Jean de Lemarck created the
