Study Notes
Eukarya and Protists
- The protists belong to the Eukarya domain, consisting of various eukaryotic organisms.
- Common ancestor of protists is the eukaryotes, distinguishing them from other domains.
Tree of Life Overview
- Vertebrates are categorized under deuterostomes and bilaterians, showcasing the evolutionary lineage of animals.
- Sub-category Opisthokonts includes multiple significant groups leading to complex life forms.
Major Clades under Vertebrates
- Sarcopterygii: Lobe-finned fishes leading to tetrapods.
-
Tetrapoda: Emphasizes the transition from aquatic to terrestrial life.
-
Amniota: Grouping that includes reptiles, birds, and mammals, showcasing evolutionary adaptations.
- Reptilia: Diverse group comprising crocodilians, birds (Aves), turtles (Testudines), and lizards/snake.
- Great Apes: Encompasses modern humans (Homo sapiens), chimpanzees, and unique species like the duck-billed platypus.
- Mammalia: Diverse class including amphibians, lungfish, and ancient lineages like coelacanths.
-
Amniota: Grouping that includes reptiles, birds, and mammals, showcasing evolutionary adaptations.
Protostomes and Other Life Forms
- Protostomes: Include several major groups like echinoderms (starfish), cephalopods (octopuses), and simpler organisms like sponges and cnidarians.
- Fungi and various protist groups (Amoebozoans, Stramenophiles) reveal early evolutionary forms and diversity.
Plant Lineage
- Angiosperms and Gymnosperms showcase the evolution of flowering and non-flowering plants.
- Green Algae: Includes stoneworts and chlorophytes, highlighting the diversity and evolutionary significance of aquatic plants.
- Red algae and other protist classifications (Rhizaria, Discoba) illustrate the complexity of photosynthetic life.
Microbial Life
- Archaea: Includes specific clades like Asgard and DPANN, representing early branching groups of life.
- Bacteria: Encompass major groups like proteobacteria and cyanobacteria, foundational to life on Earth.
Plants and Green Lineage
- Land Plants: The evolution of green plants, particularly within the Plantae group, marks significant adaptations for terrestrial environments.
- The classification into vascular plants and seed plants illustrates important evolutionary milestones in plant development.
