Resource summary

Unit B: Evidence of Evolution
1 Taxonomy
1.1 Identify Organisms
1.2 Provide a basis for recognizing a group
1.3 CARL LINNAEUS
1.3.1 Developed current system for biological classification
1.3.1.1 Based on physical and structural characterisitics
1.3.1.2 Kingdom - Phylum - Class - Order - Family - Genus - Species

Annotations:

  • Kings Play Cards On Fine Green Silk
1.4 Taxon (Taxa)

Annotations:

  • Category to classify organisms
2 Binomial Nomenclature
2.1 Latin
2.2 Uses Genus & Species

Annotations:

  • Only first name is capitalized In type it is italicized Written it is underlined
3 Kingdom Domains
3.1 Bacteria

Annotations:

  • Unicellular prokaryotes (don't have a nuclear envelope)
3.2 Archaea

Annotations:

  • Similar to bacteria but have significant differences
3.3 Eukarya

Annotations:

  • Multi and unicellular eukaryotes (have a nuclear envelope)
4 6 Kingdoms
4.1 Eubacteria

Annotations:

  • No nucleus, single celled, hetero/auto trophs, inhabit a variety of areas
4.2 Archaebacteria

Annotations:

  • No nucleus, single celled, hetero/auto trophs, live in extreme environments
4.3 Animalia

Annotations:

  • Nucleus, multicellular, heterotrophs, ingest food & are mobile
4.4 Plantae

Annotations:

  • Nucleus, multicellular, autotrophs, most are sessile
4.5 Fungi

Annotations:

  • Nucleus, multi/unicellular, heterotrophs, secrete enzymes & digest food externally  
4.6 Protista

Annotations:

  • Have nucleus, multicellular, hetero/atuo trophs, many nutrition mechanisms
5 Phylogeny

Annotations:

  • Evolution of a particular species on a phylogenic tree starting at most ancestral form
6 Dichotomous Keys

Annotations:

  • Used to identify organisms - yes/no statements
7 FOssil Evidence
7.1 Depth doesn't always indicate age
7.1.1 Radiometric dating is best
7.1.1.1 Half life: amount of time it takes for half the parent to form into the daughter isotope
7.2 DIRECT & PHYSICAL EVIDENCE
7.2.1 Different species lived in the past
7.2.2 Complexity increases from past to present
7.2.3 Living species match fossils in their area
8 Biogeographic Evidence
8.1 PANGEA

Annotations:

  • Fossils older that 150MYA lived on PANGEA and that is why they are found on many continents
8.2 New Islands
8.2.1 Endemic Species (ex - Hawaii)
9 Anatomical Evidence
9.1 Homologous Features

Annotations:

  • Similar structures but different functions  - give evidence of evolutionary relationship
9.2 Analogous Features

Annotations:

  • Same structure and function but don't have evolutionary relationship
9.3 Vestigial Features

Annotations:

  • No useful purpose Ex) Whales have a pelvic bone
9.4 Embryonic Development

Annotations:

  • At the first stages of our embryonic development, we look like lots of other organisms which shows evolutionary relationship
10 Biochemical Evidence
10.1 Similar DNA sequences indicate evolutionary relationships
11 Evidence from Artificial Selection
11.1 HUmans can select & breed traits quickly so these changes could've easily occurred naturally over time
