Study Notes
Florida Panther Classification
- Genetic evidence reveals closer ties between Florida Panthers and cougars.
- Originally classified as Puma concolor coryi, now recognized solely as Puma concolor.
Pond Water Organisms
- Organism characteristics observed under a microscope:
- Organism One: single-celled, nucleus, large vacuole (eukaryote)
- Organism Two: single-celled, no nucleus, cell wall (bacteria)
- Organism Three: single-celled, no nucleus (possible bacteria)
- Organism Four: single-celled, nucleus (eukaryote)
Early Life on Earth
- Obligate anaerobes thrive without oxygen; obligate aerobes require it to survive.
- Earth's early atmosphere likely supported only obligate anaerobes.
Shared Characteristics in Kingdoms
- Both Kingdom Fungi and Kingdom Plantae exhibit multicellular structures.
Classification of Organisms
- Organisms with a cell wall are classified in Kingdom Plantae based on morphology observed under a microscope.
Medium Ground Finch Adaptation
- Drought in 1977 affected seed availability; larger beak size became advantageous for survival.
- Increase in average beak size in the finch population was a direct result of natural selection after the drought.
Cladogram Relationships
- Cladograms illustrate evolutionary relationships; crocodiles and birds share a closer relationship compared to other reptiles.
Lesser Panda Classification
- DNA evidence indicated lesser pandas have closer genetic ties to raccoons rather than giant pandas, challenging previous classifications.
- Genetic similarities prompt reevaluation of evolutionary relationships among species.
Homologous Gene Similarity
- Percentage similarity of homologous gene sequences: humans (100%), chimpanzees (99.6%), baboons (97.2%), dogs (91.3%).
- Baboons likely placed close to humans and chimpanzees on the cladogram due to high genetic similarity.
Future Classification Changes
- Discovery of a unique organism that doesn't consume ATP may prompt classification system changes.
- Archaebacteria, once in Kingdom Bacteria, were reassigned as a result of genetic distinctiveness, leading to the establishment of Domains.
Genetic Diversity and Mutations
- Mutations contribute to genetic diversity within populations and are a natural part of evolutionary processes.
