The Diversity of Living Things An Introduction

The Diversity of Living Things An Introduction

The Diversity of Living Things An Introduction. How many species exist on Earth?. Estimated = 8.7 million. Actual number identified by scientists = 2 million. Species – a group of organisms that can interbreed in nature & produce fertile offspring. How do scientists identify a species?.

Identifying, Naming, and Classifying Species

Identifying, Naming, and Classifying Species

Identifying, Naming, and Classifying Species. Taxonomy. the branch of biology that identifies, names, and classifies species (alive and extinct). Callicebus caquetensis, a species of titi monkey, was discovered in the Colombian Amazon. (AP, 2010). How do we identify and name a species?.

SPECIATION

SPECIATION. formation of a new species BIOLOGICAL SPECIES CONCEPT population or group of populations whose members have the potential to interbreed with one another to produce viable, fertile offspring, but who cannot produce viable, fertile offspring with members of other species.

SPECIES AND SPECIATION

SPECIES AND SPECIATION. Two major categories of evolutionary change: Evolutionary change within lineages over time (anagenesis). Splitting of lineages over time (cladogenesis). Darwin’s only figure in “The Origin of Species” (1859). MAJOR ISSUES IN SPECIATION THEORY. What is a species?

CHAPTER 24

CHAPTER 24. THE ORIGIN OF SPECIES. 1. OVERVIEW. A. Speciation Is defined as the origin of new species (process by which one species splits into two or more species) Is at the focal point of evolutionary theory which must explain how new species originate and how populations evolve
