Heritable
any genetic trait that can be passed down
are particulate
are particulate
genotype
the genetic make up of a person
phenotype
the physical expression of some genetics (also changed by environment)
Natural Selection
IS NOT RANDOM, but is not goal driven
a mechanism that operates on the phenotype and effects the individual
in time effects the population
a mechanism that operates on the phenotype and effects the individual
in time effects the population
selection on a trait is most advantageous
selective on a trait where the intermediate form is less adventurous
selection on a trait where the intrincate form is most advantageous
Theory
must be falsifiable to determine if its true
a collection of several consistent supported hypothesis
large body of conclusions
a collection of several consistent supported hypothesis
large body of conclusions
Treatment
an experiment one of multiple groups which can be compared to determine what effects the variable have on the test subject
IMPORTANT TO RANDOMIZE SO RESULTS ARE TRUE TESTS OF YOUR VARIABLE**
IMPORTANT TO RANDOMIZE SO RESULTS ARE TRUE TESTS OF YOUR VARIABLE**
hypothesis
a general single assumption that can be tested
trial
one round of an experiment
ran to increase the robustness of the data
ran to increase the robustness of the data
experimental control
The experimental control is the experiment done without the variable
done so that you can see the change that your variable has
to show whether the effects are due to chance or not

post-zygotic
mechanisms of reproductive isolation prevent the offspring from successfully developinmg into a viable fertile adult
Gergor Mendell
Identified the existance of Genes
Adaptive Radiation
when a new environmental niche opens up and a species diversifies quickly
– A new adaptive zone arises
– A new geographic area arises
or after a mass extinction
– A new adaptive zone arises
– A new geographic area arises
or after a mass extinction
prezygotic
barriers hinder meeting or fertilization of the ova mechanisms of reproductive isolation that prevent mating between different species
Habitat land vs. water
apple vs. hawthorne
Temporal active day vs. night

apple vs. hawthorne
Temporal active day vs. night
species
an animal that can mate and produce viable fertile offspring s reproductively isolated group
sympatric
a type of speciation where populations differentiate in the same geographic area
allopatrick
speciation where populations differentiate into two separate geographic areas
primitive traits
very similar to ancestral traits
ie. scale
ie. scale
systemics
the system used to classify species
**MOST COMMON FORM MORPHOLOGICAL-WHERE YOU LOOK AT PHYSICAL TRAITS
**MOST COMMON FORM MORPHOLOGICAL-WHERE YOU LOOK AT PHYSICAL TRAITS
derrived traits
a trait thats gone through many changes from the ancestral trail er
ie. scale to feather
ie. scale to feather
niche
the multidimentional place that a species occupies in the ecologial landscape
artifactual selection
when humans drive the process of evolution
genetically modified over time, pigs sheep chickens, cows corn
genetically modified over time, pigs sheep chickens, cows corn
Thomas Malthus
an economist that Darwin took ideas from
those ideas are.... growing population, limited resources, eventually competition will occur and some individuals will die
those ideas are.... growing population, limited resources, eventually competition will occur and some individuals will die
phoresy
where individuals are transported between locationd with no cost to the host
detrivore
a scavenger, or decomposer
a subset of mutualism
a subset of mutualism
matter
the name we give to everything in the world, it is recycles in an ecosystem
mutualism
where both parties benifit
equator
imaginary line on the earths surface where the sun hits most directly than pans out
commensalism
typw of interaction where one party benifits and the other is ineffected
fruigivery
consumption of fruit, a mutualistic relationshiop because the fruit is getting trsnsported to flourish and the animal is getting nutrients
biome
geographic area defined by the type of plant life
competition
interaction where individuals have to hare the same resources
energy
travels through an ecosystem
hot air
rises
cool air
sinks
primary factors that determine type of biome
temp and rainfall
why are females the choosier sex
bigger investment in the producing process, one egg vs millions of sperm
predation
the process of obtaining prey, an enormously strong natural pressure
artificial selection
farmers and other humans exerting human
preferences onto animals
preferences onto animals
mutation
A mutation is a permanent change in the DNA sequence of a gene
RANDOM there is no intentionality
RANDOM there is no intentionality
DNA
composes genes
archeian extremeophiles
bacteria that can withstand extreme conditions
nosocomical diseases
a disease that comes from hospitals usually grown to be drug reisitant
science
the unbiased
interpretation of representative
data
interpretation of representative
data
RCT
the most rigid of data
gathering, the experimental gold
standard (but data are often gathered
other ways, e.g., empirical)

double/blind test
A testing procedure, designed to eliminate biased results, in which the identity of those receiving a test treatment is concealed from both administrators and subjects until after the study is completed.
Evolution
: descent with modification
Microevolution:
at the population level:
a change in genetic makeup of the
population. Genetic drift reflects a micro
level change, in which there is a small
change (“drift”) in frequency of alleles
( = genes).

level change, in which there is a small

( = genes).
Macro evolution
change in species:
from one species to another or from one
from one species to another or from one
taxonomy
classification of organisms in an ordered system that indicates natural relationships.
population
all members of the same species living in the same niche
community
interacting collection of populations
The biological prime
directive
directive
to survive and reproduce
fruiting body
releases the spores above
ground
ground
• hyphae:
tiny filaments of fungi that form a
network underground and a ��body�� above
network underground and a ��body�� above
• mycelium
the interwoven network of hyphae
underground (or in a substrate)

sexual selection
reproductive advantage (individuals interact
and gain access to mates)
SYNGAMY:
the joining of egg and sperm
