• To understand how Darwin developed his
theory of evolution
I can:
• Level E: state Darwin’s Theory of Evolution
• Level D: state Darwin’s Theory of Evolution and
describe two observations that lead to his theory
• Level C: explain Darwin’s Theory of Evolution and
apply it to classification of species
“Ignorance more frequently begets confidence
than does knowledge: it is those who know
little, not those who know much, who so
positively assert that this or that problem will
never be solved by science”
Charles Darwin
(12 February 1809 – 19 April 1882)
• Conducted research throughout the world (most
specifically in the Galapagos islands off the coast
of Ecuador)
• After looking at the similarities and differences
between various animals around the world he
developed a theory on the origin of species
• Wrote a book called ‘On the Origin of Species’
Evidence for Evolution
• Fossil Record
• Variations within and between current species
• Looked at how fossils developed and changed
over time
Main Idea:
• Gradual changes in species due to genetic
variation leads to the development of new
species via Natural Selection
• i.e. All species come from the same ancestor
species
– Including humans
TASK:
• Use the internet to fill in the glossary like the
one posted on the board
• Once you have filled out the glossary...
Evolution?
• The book ends with the following statement:
“There is grandeur in this view of life, with its
several powers, having been originally breathed
into a few forms or into one; and that, whilst this
planet has gone cycling on according to the fixed
law of gravity, from so simple a beginning endless
forms most beautiful and wonderful have been,
and are being, evolved.”
