4.2.2 Classification and evolution
the biological classification of species (taxonomic groups)
the binomial system of naming species
advantage of such a system
the features used to classify organisms into
the five kingdoms
Prokaryotae
Protoctista
Fungi
Plantae
Animalia
the evidence that has led to new classification systems, such as the three domains of life, which clarifies relationship
use of similarities in
biological molecules and other genetic evidence
details of the three domains
a comparison of
the kingdom and domain classification systems
the relationship between classification and
phylogeny
divergent evolution
homologous structures
the evidence for the theory of evolution by natural selection
the contribution of Darwin and Wallace in formulating the theory of evolution by natural selection
fossil evidence
molecular evidence
DNA
proteins
the different types of variation
intraspecific and interspecific variation
continuous variation
causes
examples
discontinuous variation
causes
examples
use standard deviation to
measure the spread of a set of data
how is SD different from range?
benefits of SD
drawing error bars
what do overlapping error bars suggest?
Student’s t-test to compare
means of data values of
two populations
unpaired
when do you use it?
paired
when do you use it?
what do you conclude if...
t value > CV
t value < CV
the Spearman’s rank correlation coefficient to
consider the
relationship of the data
when do you use it?
details about what the correlation coefficient can tell you
the different types of adaptations of organisms to
their environment
anatomical
physiological
behavioural
how does
convergent evolution
relate to adaptations?
What are stages (the mechanism) by which
natural selection
can affect the characteristics of a population over time?
how evolution in some species has implications
for human populations
evolution of pesticide resistance in
insects
drug resistance in microorganisms
