LO = What are the key features of the biological approach?
Almost every
cell in your
body contains
a nucleus
(red blood cells are the only
cells without a nucleus)
LO = What are the key features of the biological approach?
Within each
nucleus (apart
from the sex
cells) there are
46 of these
structures,
known as
Chromosomes
LO = What are the key features of the biological approach?
The
Chromosomes
are made up of a
chemical called
DNA. The DNA
carries units of
information...
LO = What are the key features of the biological approach?
These units of
information are
called genes and
these influence
our bodily
structure,
function and
BEHAVIOUR

In groups of 4 consider the stimuli around the
room, some of you will be selected to explain
your points to the rest of the class so be on
your toes!!
 Mice and rats
 Bock and Goode (1996)
 Selective breeding

In 1859 Charles Darwin published the Origin
of the Species
This states that all species of all living things
have evolved over time from common
ancestors through the process of natural
selection

RANDOM physical and
behavioural changes to a
species either enable it to
adapt to its environment
and survive or they
disadvantage it in some
way and it dies out
These ‘stronger genes’
which offer an advantage
are passed onto the next
generation and the
‘weaker genes’ die out

This is just an example of natural selection
specifically to do with attracting a mate
E.g. A peacock has a very large cumbersome
tail which has no purpose other than to
attract a mate
