This document discusses evidence for evolution and classification of biodiversity. It covers topics such as natural selection, cladistics, and the binomial system of naming species. Key points include: natural selection can occur if there is genetic variation within a species, and it increases traits that aid survival; cladistics uses genetic evidence like DNA sequences to deduce evolutionary relationships between species and reconstruct the tree of life; and scientists use a universal binomial system and taxonomic hierarchy to systematically classify and name all identified species.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

3. 5.1 Evidence for Evolution5.1 Evidence for Evolution
Essential idea:
There is overwhelming evidence for the evolution of life on
Earth.
Nature of science:
Looking for patterns, trends and discrepancies—there are
common features in the bone structure of vertebrate
limbs despite their varied use.
4. 5.1 Evidence for Evolution5.1 Evidence for Evolution
Understandings:
•Evolution occurs when heritable characteristics of a
species change.
•The fossil record provides evidence for evolution.
•Selective breeding of domesticated animals shows that
artificial selection can cause evolution.
•Evolution of homologous structures by adaptive radiation
explains similarities in structure when there are
differences in function.
5. 5.1 Evidence for Evolution5.1 Evidence for Evolution
• Populations of a species can gradually diverge into
separate species by evolution.
• Continuous variation across the geographical range of
related populations matches the concept of gradual
divergence.
6. 5.1 Evidence for Evolution5.1 Evidence for Evolution
Applications and skills:
•Application: Development of melanistic insects in polluted
areas.
•Application: Comparison of the pentadactyl limb of
mammals, birds, amphibians and reptiles with different
methods of locomotion.
7. 5.1 Evidence for Evolution5.1 Evidence for Evolution
Theory of knowledge:
•Evolutionary history is an especially challenging area of
science because experiments cannot be performed to
establish past events or their causes. There are
nonetheless scientific methods of establishing beyond
reasonable doubt what happened in some cases. How do
these methods compare to those used by historians to
reconstruct the past?
9. 5.2 Natural Selection5.2 Natural Selection
Essential idea:
The diversity of life has evolved and continues to evolve by
natural selection.
Nature of science:
Use theories to explain natural phenomena—the theory of
evolution by natural selection can explain the development
of antibiotic resistance in bacteria.
10. 5.2 Natural Selection5.2 Natural Selection
Understandings:
•Natural selection can only occur if there is variation
among members of the same species.
•Mutation, meiosis and sexual reproduction cause variation
between individuals in a species.
•Adaptations are characteristics that make an individual
suited to its environment and way of life.
•Species tend to produce more offspring than the
environment can support.
11. 5.2 Natural Selection5.2 Natural Selection
• Individuals that are better adapted tend to survive and
produce more offspring while the less well adapted tend
to die or produce fewer offspring.
• Individuals that reproduce pass on characteristics to
their offspring.
• Natural selection increases the frequency of
characteristics that make individuals better adapted and
decreases the frequency of other characteristics
leading to changes within the species.
12. 5.2 Natural Selection5.2 Natural Selection
Applications and skills:
•Application: Changes in beaks of finches on Daphne Major.
•Application: Evolution of antibiotic resistance in bacteria.
•Guidance:
•Students should be clear that characteristics acquired
during the lifetime of an individual are not heritable. The
term Lamarckism is not required.
13. 5.2 Natural Selection5.2 Natural Selection
Theory of knowledge:
•Natural Selection is a theory. How much evidence is
required to support a theory and what sort of counter
evidence is required to refute it?
14. 5.3 Classification of biodiversity5.3 Classification of biodiversity

15. 5.3 Classification of biodiversity5.3 Classification of biodiversity
Essential idea:
Species are named and classified using an internationally
agreed system.
Nature of science:
Cooperation and collaboration between groups of scientists
—scientists use the binomial system to identify a species
rather than the many different local names.
16. 5.3 Classification of biodiversity5.3 Classification of biodiversity
Understandings:
•The binomial system of names for species is universal
among biologists and has been agreed and developed at a
series of congresses.
•When species are discovered they are given scientific
names using the binomial system.
•Taxonomists classify species using a hierarchy of taxa.
•All organisms are classified into three domains.
•The principal taxa for classifying eukaryotes are kingdom,
phylum, class, order, family, genus and species.
17. 5.3 Classification of biodiversity5.3 Classification of biodiversity
• In a natural classification, the genus and accompanying
higher taxa consist of all the species that have evolved
from one common ancestral species.
• Taxonomists sometimes reclassify groups of species
when new evidence shows that a previous taxon contains
species that have evolved from different ancestral
species.
• Natural classifications help in identification of species
and allow the prediction of characteristics shared by
species within a group.
18. 5.3 Classification of biodiversity5.3 Classification of biodiversity
Applications and skills:
•Application: Classification of one plant and one animal
species from domain to species level.
•Application: Recognition features of bryophyta,
filicinophyta, coniferophyta and angiospermophyta.
•Application: Recognition features of porifera, cnidaria,
platylhelmintha, annelida, mollusca, arthropoda and
chordata.
•Application: Recognition of features of birds, mammals,
amphibians, reptiles and fish.
•Skill: Construction of dichotomous keys for use in
identifying specimens.
19. 5.3 Classification of biodiversity5.3 Classification of biodiversity
Guidance:
•Archaea, eubacteria and eukaryote should be used for the
three domains.
•Members of these domains should be referred to as
archaeans, bacteria and eukaryotes.
•Students should know which plant phyla have vascular
tissue, but other internal details are not required.
•Recognition features expected for the selected animal
phyla are those that are most useful in distinguishing the
groups from each other and full descriptions of the
characteristics of each phylum are not needed.
•Viruses are not classified as living organisms.
20. 5.3 Classification of biodiversity5.3 Classification of biodiversity
International-mindedness:
•There are international codes of nomenclature and
agreements as to the principles to be followed in the
classification of living organisms.
21. 5.3 Classification of biodiversity5.3 Classification of biodiversity
Theory of knowledge:
•The adoption of a system of binomial nomenclature is
largely due to Swedish botanist and physician Carolus
Linnaeus (1707–1778). Linnaeus also defined four groups of
humans, and the divisions were based on both physical and
social traits. By 21st-century standards, his descriptions
can be regarded as racist. How does the social context of
scientific work affect the methods and findings of
research? Is it necessary to consider the social context
when evaluating ethical aspects of knowledge claims?
23. 5.4 Cladistics5.4 Cladistics
Essential idea:
The ancestry of groups of species can be deduced by
comparing their base or amino acid sequences.
Nature of science:
Falsification of theories with one theory being superseded
by another—plant families have been reclassified as a
result of evidence from cladistics.
24. 5.4 Cladistics5.4 Cladistics
Understandings:
•A clade is a group of organisms that have evolved from a
common ancestor.
•Evidence for which species are part of a clade can be
obtained from the base sequences of a gene or the
corresponding amino acid sequence of a protein.
•Sequence differences accumulate gradually so there is a
positive correlation between the number of differences
between two species and the time since they diverged
from a common ancestor.
•Traits can be analogous or homologous.
25. 5.4 Cladistics5.4 Cladistics
• Cladograms are tree diagrams that show the most
probable sequence of divergence in clades.
• Evidence from cladistics has shown that classifications
of some groups based on structure did not correspond
with the evolutionary origins of a group or species.
26. 5.4 Cladistics5.4 Cladistics
Applications and skills:
•Application: Cladograms including humans and other
primates.
•Application: Reclassification of the figwort family using
evidence from cladistics.
•Skill: Analysis of cladograms to deduce evolutionary
relationships.
27. 5.4 Cladistics5.4 Cladistics
Theory of knowledge:
•A major step forward in the study of bacteria was the
recognition in 1977 by Carl Woese that Archaea have a
separate line of evolutionary descent from bacteria.
Famous scientists, including Luria and Mayr, objected to
his division of the prokaryotes. To what extent is
conservatism in science desirable?
