BIOL 1202 Chapter : Systematics
Document Summary
Population of species on earth: about 10 million species (10,000,000) To see who is the most related to each other, take a dna swab from the cheek and compare them to see whose is the closest. All living things are related to all other living things on the planet and that is a fact. 200,000 years ago is when we stop finding fossil records of homo sapiens records. Homo sapiens come from pre existing cells which come from pre existing species. About 50 trillion cells make up our body. Humans are eukaryotes and multicellular and animals by definition. All the cells come from pre existing cells which come from haploid and diploid cells. 4. 5-4. 6 billion years old and that is an observational fact. All life on the planet comes from a common ancestor. Taxonomy is the branch of biology concerned with naming and classifying the diverse forms of life on the planet.
