Evolution and species
The term used to describe the variety of living things on earth.
Biodiversity
The mechanism by which advantageous traits become more common in populations over generations.
Natural selection
Features that improve an organism's survival or reproduction in its environment.
Adaptations
Define species
Organisms that can interbreed and produce fertile offspring
Camel hump is an example of which adaptation
Structural adaptation
The type of adaptation that involves changes in an organisim's actions that help it survive in its environment.
Behavioural adaptations
Natural selection can be understood uisng which three terms
Variation, Selection and competition
Define evolution
Change in gene pool/allele frequency
Give any two of the mechanism of evolution
Gene flow/Population shrink, natural selection
Traits/characteristics shaped by natural selection that increases and organisms chance of survival and reproduction
Adaptation
Evolution always lead to new species
(True/False)
False
One ancestral species giving rise to multiple species in different ecological niches(Adaptive radiation OR Geographical isolation)
Adaptive radiation
Give any 3 evidences of Evolution
Homologous structures, embryology, geographical isolation
When populations diverge to the point that they can no longer interbreed successfully. (Adaptive radiation OR Reproductive isolation)
Reproductive isolation - Speciation
The five finger mechanism represent Microevolution OR Macroevolution(means speciation)
Microevolution
