Chapter 1- Evolution, the Themes of Biology, and Scientific Inquiry
CONCEPT 1.2- The Core Theme: Evolution accounts for the unity and
diversity of life
Keep = Kingdom
Pond = Phylum
Clean = Class
Or = Order
Froggy = Family
Gets = Genus
Sick = species
Taxonomy- the branch of biology that names and classifies species,
formalizes this ordering of species into groups of increasing bread, based
on the degree to which they share characteristics.
Bacteria and archae are prokaryotic.
Bacteria are the most diverse
Eukarya are eukaryotes
This domain includes three kingdoms of multicellular eukaryotes:
kingdoms Plantae, Fungi, and Animalia.
Plants produce their own sugars and other food by photosynthesis,
fungi absorb dissolved nutrients from their surroundings, and
animals obtain food by eating and digesting other organisms.
Single-celled eukaryotes= protists
The cilia of the single-celled Paramecium propel the organism through
pond water.
Evolution- the process of change that has transformed life on Earth,
accounts for the unity and diversity of life. It also explains evolutionary
adaptation- the match of organisms to their environments.
