Speciation and Evolutionary Relationships

Phylogeny is...

• The study of classification of different species

• The study of the evolutionary history of a species

• The study of prehistoric life

• The study of the distribution of different species

Phylogenetic trees show...

• Evolutionary relationships between different species

• How one species has evolved through time

• Which species has evolved the most

• Which species have evolved from other species
