The subconscious as a deposit for the thoughts of apes and hominids

How many thoughts have apes had over the years? It is clear from science that we descended from some sort of ape and we share a common ancestor with modern apes. What did these ancestor think of? Perhaps he mused on the extent of the sky, perhaps he revelled in the viridian grass.

Imagine Homo erectus sitting on a hinterland looking out to sea, the placid waves lapping upon some primeval beach, perhaps he has built a raft out of pine logs. His core behavioural characteristics are stowed away in his brain as instinct, those hominids with the more useful instincts will pass those instincts down in the form of genes to their kin.

Imagine a certain hominid named Ken, perhaps he first invented the spear.

Now it was a natural curiosity, a basic intelligence and probably an innate aggression that led to the first spear. It is likely that these instincts that produced these behaviours such as curiosity etc. have been passed down to us in the form of expressed or unexpressed genes 

Our minds are composites of the instincts of our more successful ancestors. Thus I may have a mix of instincts from, a certain homo habilis named John, a medieval peasant named Francis etc, etc. 

By having these inherited genes we can explore the mind of our ancestors through examining our own subconscious. 

 
Taking a look at my own subconscious memories of my ancestors:
  
Pierre Allemand  (1662 – 1691) a ships pilot, explorer and fur-trader in the New World during the later 17th century.

Experiences: Remember this one, a bit boring lots of sea and fur.

Pristimantis appendiculatus  (2 million AD - 2 million AD) was a frog in the Strabomantidae family found in Colombia and Ecuador.

Experiences: Bit boring lots of flies.

Feldspar  (4 Billion AD - 3.995 Billion AD) Was a piece of Feldspar.

Experiences: Bit boring, was a rock
