The main mechanisms of speciation
Слайд 4Success criteria
1. Apply previous knowledge about main mechanisms of speciation.
2.
Classify correctly at least four examples out of five.
Слайд 5Terminology
Speciation, allopatric, sympatric, isolation: ecological and geographic, parapatric, peripatric, variation
within population, adaptation, new species, mechanical isolation, behavioral isolation, gene pool, genoms, allele frequency, individuals, deme, anceryral species, barrier, polyploidy,
Слайд 6Speciation
one species diverging
into a new species
Causes
-geographic isolation
-
behavior or temporal changes
Species B
Species C
Species A
Specific Change over time
Слайд 17
Speciation
Common Ancestor
When a species evolves
(branches) into a
new species as a result
of natural selection; the new species can no longer interbreed producting fertile offspring.
Examples
-geographical isolation -mating behavior -breeding habits -changes in food sources
Examples
-geographical isolation -mating behavior -breeding habits -changes in food sources
Maltose Food
Starch Food
Many generations pass
Слайд 22 Two populations are separated by geographical barriers such as, Mountains,
Lakes, Oceans, Rivers, Deserts…over time speciation will occur.
Geographic Isolation

Abert squirrel has a light colored belly and lives on the South Rim
