Does is make sense to talk about human nature?

(Debate on 1/9/2012) What do we know about human nature behind its mask? We often say it’s ‘human nature’ to be selfish, to be greedy, to be jealous, to be cruel, to be competitive, to be ambitious…  But is there any scientific base to prove that these are unique attributes of humanoid?

Human nature is incredibly complex.  The purpose of the discussion is to differentiate the nature of humanoid from the nature of other animals.  We can then determine whether we were created by God, or whether we were descendants of monkeys.

In contrast to the debate on religions and morality, several of our scientifically minded philosophers gave fascinating answers branching out to the studies of neurology, stem-cell research, and brain scans.  We discovered the shocking truth that Human Nature, in the age of genetic engineering, is edging towards a new stage on the evolution ladder of primates.  I wonder if we are heading towards a Brave New World as prophesied by Aldous Huxley, in which only Alpha and Beta the Super-human will still be natural born humanoid, while the rest, especially Epsilons will be reproduced as millions of duplicates spawn from one single egg, deliberately created with limited cognitive and physical abilities, so that they can be easily conditioned to perform simple and repetitive tasks. We have heard of the horror of Dolly the cloned sheep.  Brace ourselves for the invasion of Epsilon clones.
