Fossil evidence For Human Evolution 2

Question 1

What else is evidence for human evolution

Answer 1

Stone tools

Question 2

How can you tell the ages of the fossils

Answer 2

The stone tools gradually became more complex ( so their brains must been getting larger )

Question 3

What tool use did Homo habilis do ( 2.5-1.5 million years ago )

Answer 3

Simple stone tools were made called pebbles tools by hitting rocks together to make sharp flakes
These can be used to scrape meat from bones or to crack bones open

Question 4

What tool use did Homo Erectus do ( 2-0.3 million years ago )

Answer 4

They sculpted rocks into shapes to produce more complex tools like simple hand-axes.
These could be used to hunt, dig, chop and scrape meat off bones

Question 5

What tool use did Homo Neanderthalis do ( 300,000-25,0000 million years ago )

Answer 5

More complex tools. Evidence of flint tools, pointed tools and wooden spears

Question 6

What tool use did Homo Sapiends do ( 200,000 years ago — present )

Answer 6

Flint tools widely used. Pointed tools including arrowheads, fish hooks, buttons and needles appears around 50,000 years ago

Question 7

How can Scientists work out how old something is

Answer 7

Structural features
Simpler tools are likely to be older than more complex tools
Using stratigraphy—rock layers. Older rock layers are normally found below the younger layers, so tools or fossils in deeper layers are usually older
Carbon containing material—e.g. a wooden handle
