How many species???

Each year, researchers report more than 15,000 new species

They estimate there are 8.7 million species on the planet, plus or minus 1.3 million

Page 3: Each year, researchers report more than 15,000 new species They estimate there are 8.7 million species on the planet, plus or minus 1.3 million

Taxonomy

• Branch of biology that groups and names organisms based on studies of their different characteristics.

Page 4: Each year, researchers report more than 15,000 new species They estimate there are 8.7 million species on the planet, plus or minus 1.3 million

The Diversity of Life has Unity

All living things have cell All living things have DNA or RNA

Page 5: Each year, researchers report more than 15,000 new species They estimate there are 8.7 million species on the planet, plus or minus 1.3 million

Carolus Linnaeus Father of modern taxonomy

Rules of Binomial Nomenclature

Genus First Word Capitalized Underlined or italicized

Ex. Acer or Acer

Taxon’s

categories of organisms grouped by similar characteristics

Kingdoms – broadest category (6 kingdoms currently)

Species – most specific category

Page 10: Each year, researchers report more than 15,000 new species They estimate there are 8.7 million species on the planet, plus or minus 1.3 million

Species –organism that can reproduce and create viable offspring

Viable means offspring that can also reproduce

Exceptions- mule or zebroid
