- Validation of Scientific Ideas
- -Scientific Journals -Peer Reviews -Conferences
- Is the paper valid, significant and original

- Evolution
- Natural Selection- Population shows genetic diversity due to a variety of alleles caused by mutations
- Environmental conditions change
- Natural Selection reduces reproduction of some individuals
- Some individuals pass on more alleles to nest generation
- Over generations the frequency of these alleles increases
- Some individuals pass on more alleles to nest generation
- Natural Selection reduces reproduction of some individuals
- Environmental conditions change
- Niche-the role of the organisms in the community
- Adaptation
- Anatomical-Physical/structure
- Behavioral- what the organism does
- Physical-Internal Functioning
- Behavioral- what the organism does
- Anatomical-Physical/structure
- Natural Selection- Population shows genetic diversity due to a variety of alleles caused by mutations
- Speciation
- Allopatric Speciation- Physical/geographical isolation
- Sympatric Speciation- reproductive isolation
- Isolation:
- Geographical-Physical Barrier
- Habitat-occupy different habitats in same area but don't meet to breed
- Seasonal/temporal-same area but active for reproduction @different times
- Mechanical-reproductive organs no longer fit togetehr
- Behavioral-no response to reproductive display's
- Gametic-male and female gametes from different populations incompatible with each other
- Behavioral-no response to reproductive display's
- Mechanical-reproductive organs no longer fit togetehr
- Seasonal/temporal-same area but active for reproduction @different times
- Habitat-occupy different habitats in same area but don't meet to breed
- Geographical-Physical Barrier
- Allopatric Speciation- Physical/geographical isolation
- Biodiversity
- Equation
- N=total of all species
- n= total no of each individual species
- N=total of all species
- Great vairety of alleles within a gene pool, within a species and area
- Equation
- Ex-Situ Conservation
- Zoo's
- Education; Scientific Research, Captive Breeding
- Maintain diversity-No repeated breeding, selective partners, keep a database of breeding history
- Education; Scientific Research, Captive Breeding
- Seed Banks
- Seed's collected from a no of individuals, x'rayed to see embryo, dried, stored @ cold temperatures, periodic germination tests to check viability
- Zoo's
- In-Situ Conservation
- Conserve in natural habitats
- National parks; wildlife reserves;world biosphere reserves; SSSI
- Monitored; protected from human activity; a suitable size; not isolated from other reserves
- Conserve in natural habitats
- Molecular Phylogeny
- Gel-Electrophoresis: DNA fragments are loaded into agrose gel. DNA cut into fragments and treated to glow in UV light, creating an electophotogram.
