A change in the characteristics of a population of organisms that occurs over the course of generations

a group of individuals that can breed together and produce fertile offspring

process by which populations adapt to a changing environment

all species present on earth today are descendents of a single common ancestor and all species represent the product of millions of years of accumulated microevolutionary changes

inheritance of aquired characteristics

• Domain
• kingdom
• phylum
• class
• order
• family
• genus
• species

2 part name of species - latin

non-functioning features a common ancestor had use of

• fossil record
• vestigal traits
• anatomical similarities
• embryonic development
• DNA
• biological classifications
• biography

chemical that kills or disables bacteria

one that can't be cured by standard antibiotics

• individuals of population vary
• some variation passed to offspring
• populations produce more offspring than will survive
• survival and reproduction are not random

True

humans delibrately control survival and reproduction

• extinct species don't evolve
• it doesn't lead to ideal organism
• adapts to current environment

populations traits change in a more faborable selection

extreme varients in a population are selected against traits of the population that stay the same

• combination drug therapy
• long term treatment maintenance
• no drugs for viral maintenance

category in linean classification system

relies on reproductive isolation

• habitat isolation
• behavioral
• mechanical
• temporal
• gamete

• hybrid inviability
• hybrid sterility

populations distanced by geographic barriers

chromosome numbers byond the diploid number

species that look alike

• allele frequencies will remain stable if
• no mutation,
• no genetic drift,
• no natural selection,
• no gene flow
• no random mating

Change in Allele frequency due to chance

in an isolated population, the same genes get used over and over

dramatic but short-lived reduction in population

non-random mating - prefer someone like self

variety within and among living species

life's history subdivided into a time period defined by a set of fossils

• Cenozoic
• Mesozoic
• Paleozoic
• pre-cambrian

• plantae
• animalia
• fungi
• protista

• Eukaryotic
• bacteria
• archaea

the task of classifying life into groups according to characteristics

classifying organisms according to common ancestry of species

true

mitochondria and cloroplasts descended from bacteria that took up residence inside larger primitive eykaryotes

multicellular organisms that make their living by ingesting orther organisms and are motile
