Question 1 What are genes

slide 4:

If you imagine your DNA as a cookbook then your genes are the recipes. Written in the DNA alphabet - A T C and G - the recipes genes tell your cells how to function and what traits to express. For example if you have curly hair it is because the genes you inherited from your parents are instructing your hair follicle cells to make curly strands.

slide 5:

Human beings have between 20000 and 25000 genes. Each one of us has the same set of genes.

slide 6:

Question 2 How large a part of our personality is inherited

slide 7:

How large a part of your personality is learned _____ How large a part of your personality is inherited _____

slide 8:

Personality traits are between 40 and 60 heritable. page 104.

slide 9:

6 creativity studies of identical twins show that 25 to 40 of what we do innovatively stems from genetics. That means that about 2/3 of our innovation skills come through learning. location 311.

slide 10:

The human population will become more alike as races merge.

Question 3 What characterizes us homo sapiens

slide 13:

160000 – 200000 years ago is the origin of our species homo sapiens. March 1 2012. minute 7.

slide 14: minute 7.

slide 15:

Around 50000 years ago about a hundred people moved from Africa to Asia. Everyone alive today who has any non-African ancestors is probably descended from this group.

slide 16: Neanderthall Homo sapiens

slide 17: minute 5. Contrary to our ancestors Homo erectus and the Neanderthalls we – homo sapiens – have the ability to learn from each other build on ideas of each other. Therefore we develop more than Homo erectus and the Neanderthals did.

Question 4 Who was homo erectus

slide 21:

Our ancestors the Homo erectus evolved about 2 millions years ago on the African savanna.

slide 22: minute 7.

slide 23: How homo erectus may have looked.

slide 24:

For 1 million years homo erectus made the same hand axes over and over again. In other words they were not good at learning from each other for example watch and copy from others. As a result they could not improve on ideas of each other.

Question 5 Who were neanderthalls

slide 27:

Between 1 and 4 of the DNA of modern Europeans and their descendants on other continents is of Neanderthal origin. Neanderthals were larger and heavier than us.

slide 28:

How neanderthals may have looked

slide 29:

Neanderthals lived in Europe and Central Asia and died out 40000 years ago.

slide 30: minute 7.

slide 31:

The tools of the Neanderthals were somewhat more complicated than those of homo erectus. The tools of neanderthals also changed very little over the 300000 years that neanderthals lived. minute 5.
