    • debated start date; unsure if it starts with agriculture or industrialization.
    • primarily proposed by Paul Crutzen
  49. Number of described species on Earth
    1.7 million
  50. Natural Selection
    • Primary mechanism for evolutionary chage
    • Depends on inherited variability of traits which may be more advantageous and allow individuals to produce more offspring.
  51. Selection 
    acts upon individuals
  52. Evolution
    acts on populations
  53. Gene flow
    exchange of genetic material within a population
  54. Phylogeny 
    evolutionary history of an organism
  55. systematics
    field of study that seeks to reconstruct phylogenies
  56. Phyletic Evolution
    change over time within a single lingeage (from one ancestor)
  57. Types of reproductive isolating mechanisms
    • Pre-mating: mating not even attempted
    • Post-mating: individuals capable of mating, but either have offspring that are sterile or not viable.
  58. Positive Assortative Mating
    courtship behaviors directed toward phenotypically similar individuals
  59. Negative Assortative Mating
    courtship behaviors directed toward phenotypically dissimilar individuals
  60. Carl Linnaeus
    • Binomial nomenclature
    • each species is given a name in Greek or Latin consisting of a capitalized name indicated the genus and a lower case name indicating the species
  61. Analogous structures
    • structures that develop though convergent evolution 
    • often used in phenetics
  62. Homologous Structures
    indicate a common evolutionary origin, regardless of how the structure appears
  63. Adaptive radiation
    process through which one taxon gives rise to many others that exploit availableniches.
  64. Polymorphism
    two or more discrete phenotypes in a sympatric population
  65. Microsatellites
    repeated sequences of 1–6 base pairs of DNA. High mutation rates result in lots ofpolymorphisms – in other words, there are lots of different alleles to examine in a microsatellite. Thesecan indicate genetic diversity within populations of the same species.
  66. Zink et al. conclusion
    dispersal is happening without human intervention.
