Chixulub crater = evidence; ~1/2 all spp. lost
mates chosen on basis of physical/behav. characteristics
says genetic makeup of small new group will slowly change in composition if small group doesn't contain same gene frequencies as ancestral group
phylogenetic tree w/fewest evolutionary events is most likely
body size increases as you go north
expressed allele
graded change in a trait along a geographical axis
missing section of DNA
K
reversible changes in gene expression w/o changes to DNA
extremities get shorter as you go north
similarities inherited from a common ancestor
change in 1 to a few nucleotides
no 2 spp can occupy same niche indefinitely
movement of genes from 1 pop to another
DES (diethylstibestrol), hexachlorobenzene, Ni+
gene that affects more than one phenotype
individuals that can't repair UV damage
the evolutionary history of an organism
when organism focuses life on single reproductive event then die
fcnal unit of evolution
selects against extremes in phenotype
uncontrolled growth of a cell
250 mya; 90+% spp. on land and sea lost
a gene that limits the production of the phenotype of an allele
when spp have overlapping niches
mating behav., courtship rituals differ
changes that occur that inhibit growth of pioneer spp
same species in the same geographical area
pops. breed at diff. times of day, year, or diff. years
non-toxic mimic toxic to confer protection
pioneers change habitat to make favorable for spp.
agent that increases mutation rate
definitionterm
two genes for two traits
physical manifestation of expressed genes
differing lifestyles or habits in pops.
2 or more pops. diverge b/c of geographical isolation
tendency for ecosystems to become more complex over time
some traits that don't enhance fitness selected because members of opp. sex find attractive
cmpds that affect histones/methylation; increase cancers
change of genetic info of a cell
place on chromosome where alleles are
isolated population becomes diff. from original population
low rate of growth
mates chosen on basis of physical/behav. characteristics
long lived, reproduce later on in life
when evolution subdivides niche for spp
device used to determine genotype of offspring
pop. almost becomes extinct, revives, but has limited genetic variation
increases frequency of extremes
offspring differ from both parents
when toxics evolve similar coloration
movement of gene on chromosome
theoretical exponential growth of an organim
reproduce as fast as possible
makes histones unwind, making transcription easier
binds to cytosines on DNA, winding DNA, making transcription more difficult
identification & classification of organisms
more than 1 complete set of chromosomes
evolution has periods of stasis and also sudden explosions of new spp.
species that have a high rate of growth
classification that includes evolutionary affinities and history of spp.
causes adjacent pyrimidines to become linked chemically
probability of survival vs. age
fewer offspring for more years
resources than are in short supply
definitionterm
high E; knocks e-s off atoms, creating free radicals
two genes for the same trait
burst of new spp. from a single lineage
no functional protein produced
theoretical community that reaches a steady state
community + abiotic factors
speciation independent of geography
short limbs, extra fingers
what you use to determine if a pop. is evolving or not
says father interested only in growth of offspring at expense of mom
chemicals that alter existing DNA nucleotides; OR nucleotide look-alikes
acquisition of same physical trait from different lineages
alternative state of a gene
difference in survival and reprod. b/c of diff. in genotypes
nonliving component of ecosystem
similar structures that evolved from different lineages
anatomical incompatibility
shifts freq. of trait a certain direction
all the genes contained in its diploid cell
repeated section of DNA
what an organism requires of its environment
group of organisms that can interbreed & produce fertile offspring
two or more genes determine a single phenotype
limit a community can handle to sustain pops.
genes that seem to be linked to all types of cancer
when allele expressed is determined only by which parent contributes
consequences that result from reproducing
tells when organism spp reproduces, how many babies, how old it gets
pioneer spp. tolerant of harsh abiotic conditions
gametes incompatible
when spp evolve differences that reduce competition
