Phylogeny studies evolutionary relationships among organisms. All living organisms share a common ancestry. Relationships are determined by genetic and anatomical similarities. Phylogenetic trees show evolutionary relationships visually
GBIF provides taxonomic and geographic occurrence data for countries. Data available in .csv or Darwin Core formats. Free account required to access GBIF data. Kenya dataset contains 700,168 records from January 2017
Genus is a taxonomic rank below family and above species. Contains species with common attributes or phylogenetic relationships. Term comes from Latin meaning "birth", "descent", or "type". About 510,000 published genus names as of 2016
DNA barcoding identifies species using short DNA sequences from specific genes. Different gene regions are used for different organism groups. COI gene is most common for animals, ITS for fungi, RuBisCO for plants
Dinosaurs first appeared during Triassic period (243-233.23 million years ago). Birds evolved from theropods during Late Jurassic epoch. Birds survived Cretaceous-Paleogene extinction event 66 million years ago
Phylogenetic tree shows evolutionary relationships between biological species. Evolved from "Great Chain of Being" concept of life progression. Early paleontological charts represented geological associations between plants and animals
