Study Notes
Taxonomic Concepts and Principles
- The notes pertain to taxonomic concepts, principles description, nomenclature, identification, and classification
Phylogenetics Etymology
- The word "phylogenetics" is derived from the Greek words "phylon" and "genetikos"
- The Greek word "phylon" means "tribe" or "race"
- The Greek word "genetikos" means "relative to birth" or "origin"
Phylogenetics Definition
- Phylogenetics is a method of classifying organisms based on their evolutionary history
- Phylogenetics uses genetic similarities and common ancestors to group organisms into clades, which are nested hierarchies
- The study of the evolutionary history of life using genetics is done through phylogenetic inference
Ernst Haeckel
- Ernst Haeckel was a German biologist known for his work on phylogenetic trees
- Haeckel is considered a pioneer of Darwinian biological anthropology
- Phylogenetics is also termed as the "PhyloCode" system
- Haeckel wrote "The Genesis of Man (Anthropogeny)", which argued in favor of human evolution
- He used and developed the terms "ecology", "phylum", "phylogeny", and "Protista"
- Haeckel discovered, described, and named thousands of new species
Phylogenetic Tree
- A phylogenetic tree, also known as the Tree of Life, illustrates the evolutionary pathways of various organisms, including humans
Phylogenetics and Cladistics
- Phylogenetics focuses on evolutionary relationships between organisms
- It uses "cladistics," where organisms are grouped based on shared derived characteristics without strict hierarchical ranks
Recapitulation Theory
- An organism's development parallels its species' evolutionary development
Sequence-Based Embryology
- Sequence-based phylogenetic embryology involves comparative embryology based on developmental sequence
Significance of Phylogenetics
- Phylogenetics has uses in epidemiology for tracking the spread of pathogens, such as HIV
- It is also used in conservation to track and preserve critically endangered species
- Phylogenetics enables understanding of how continents and ecosystems have changed over time through biogeography
- It allows appreciation of concepts on how species have evolved and adapted over time, understanding evolution
