Revise assumed knowledge:
SC4-14LW
relates the structure and function of living things to their classification, survival and
reproduction
□
SC4-15LW
explains how new biological evidence changes people’s understanding of the world
LW4 The theory of evolution by natural selection explains the diversity of living things and is supported by
a range of scientific evidence. (ACSSU185)
5LW4a. describe scientific evidence that present-day organisms have evolved from
□
organisms in the past
Explain the process of Lamark’s explanation of evolution, and identify its flaws
Provide examples of evidence used by Darwin and other scientists during the
development of the scientific theory of evolution
Activity 2.1.1: Analysing beaks Oxford pg 62
Describe how the theory of plate tectonics can help explain the biogeography of the
world
Compare artificial and natural selection using examples.
Activity 2.1.2: Sexual selection in humans Oxford pg 65
Checkpoint 2.1
Complete questions as homework, a mid-topic test or as a class activity. Use individual
student scores to assign support, consolidate or extend checkpoint worksheets from the
Teacher obook as required. Oxford pg 71
5LW4c.explain, using examples, how natural selection relates to changes in a population,
e.g. in the development of resistance of bacteria to antibiotics and insects to pesticides
5LW4d.outline the roles of genes and environmental factors in the survival of organisms
in a population

Identify the four requirements of natural selection
□
Natural selection
Explores how natural genetic variation within populations provides some individuals
with an advantage over others to survive their specific environmental conditions, leading
to genetic change in populations over time.
□
Activity 2.2.1: Generational change
Activity 2.2.2: Selection challenge
First hand investigation 2.2.1: Modelling the effects of natural selection Oxford pg 76-79

Questions 2.2.1 Oxford pg 78
Describe how the environmental conditions of a species put pressure on individuals
Explain why allele frequencies within a population can change over time
Recall that genetic isolation is vital for speciation and list the three main isolating
mechanisms
□

Compare and contrast allopatric and sympatric speciation
□
Speciation
Discusses the conditions required for and the processes of the evolution of a new species
from an existing population. Oxford pg 79-82
□
Evaluate the appropriateness of a scientific model and suggest improvements.
Checkpoint 2.2
Complete questions as homework, a mid-topic test or as a class activity. Use individual
student scores to assign support, consolidate or extend checkpoint worksheets from the
Teacher obook as required. Oxford pg 83
5LW4b. relate the fossil record to the age of the Earth and the time over which life has
been evolving
Explain how the fossil record is evidence for evolution
Reliable evidence
Outlines how the sheer volume and similarity of information and data from fossils and
historical artificial breeding makes them very reliable evidence for evolution. Oxford pg
84-85
Explain how fossils can be used to estimate the age of the Earth and how this is
further evidence in support of evolution
Analysing fossils
Introduces some of the ways in which fossils are used to demonstrate evolution.
Activity 2.3.1: Examining bones
Activity 2.3.2: Examining fossils
Explain how human-controlled artificial selection of domesticated species is
evidence of evolution
Explain how human-controlled artificial selection of domesticated species is
evidence of evolution
Summarise the main processes involved in the formation of fossils
Identify that the age of the fossil is the same as the rock layer where it was found,
and that the deeper the rock layer, the older it is
Describe the importance of transitional fossils and ‘living fossils’ as evidence of
evolution
Compare and contrast divergent and convergent evolution
Explain the differences between analogous and homologous structures
Use specific examples to explain how comparative anatomy, embryology and
comparative biochemistry can be used as evidence of evolution.
Analysing the living
Introduces methods of investigating evolution through living species, such as comparative
anatomy, embryology and comparative biochemistry. Oxford pgs 92-97
Checkpoint 2.3
Complete questions as homework, a mid-topic test or as a class activity. Use individual
student scores to assign support, consolidate or extend checkpoint worksheets from the
Teacher obook as required Oxford pg 98
