Biotechnology
developments in biotechnology, for example polymerase chain reaction (PCR), gel electrophoresis and DNA sequencing, have increased access to genetic information of species and provide evidence for evolution (the process of obtaining a DNA sequence is not required)
10  cards
Comparative Biochemistry
developments in the fields of comparative biochemistry (including DNA and protein sequences) and bioinformatics have enabled identification of further evidence for evolutionary relationships, which help refine existing models and theories
0  cards
Mutations

Traits for Survival
0  cards
Gene Pools
Blank 1
1  cards
Dynamic Allele Frequencies
0  cards
Genetic Diseases
the incidence of genetic diseases in particular populations illustrates the effects of different factors on the dynamics of gene pools; for example, sickle-cell anaemia
1  cards
Natural Selection
natural selection occurs when factors in the environment confer a selective advantage on specific phenotypes to enhance survival and reproduction
1  cards
Mechanisms Underpinning Evolution
includes inherited variation, struggle for existence, isolation and differential selection, producing changes to gene pools to such an extent that speciation occurs
1  cards
Fossil Record
the fossil record is incomplete and cannot represent the entire biodiversity of a time or a location due to many factors that affect fossil formation, the persistence of fossils and accessibility to fossilised remains
0  cards
Dating Techniques
sequencing a fossil record requires a combination of relative and absolute dating techniques to locate fossils onto the geological timeline
0  cards
Limitations of Dating Techniques
both relative dating techniques, including stratigraphy and index fossils, and absolute dating techniques, including radiocarbon dating and potassium-argon dating, have limitations of application
0  cards
Evolutionary Pathways
determining relatedness and possible evolutionary pathways for hominins uses evidence from comparisons of modern humans and the other great apes
7  cards
Tool Usage in Hominins
tool use is seen in a number of hominin species and the study of these tools provides important insight into the evolution of the human cognitive abilities and lifestyles
