Some people see humans as just another species of animal and think that we just need to reproduce and spread our genes and take care of our young. Others think that our status as a species or as an animal is very unimportant when put alongside our intellectual and spiritual nature.
A human being is of a kind and caring nature unless there is something wrong with them. If you find two grown men, one who is frequently angry and one who is frequently kind, the kinder one will be in better health (e.g. lower resting blood pressure, more restful sleep).
I believe in behavioural genetics for more simple species such as scorpion and dog. I think that a scorpion will probably behave like a scorpion, and I think that a poodle will probably behave like a poodle. When I'm walking dogs at my local pound, I prefer not to walk a terrier as I just don't like their personality.
Anthropologists say that humans looked just the way we do 300,000 years ago. So if you find a caveman from 200,000 years ago and give him a bath and a shave he will look just like one of us. But they say that behavioural modernity began only about 50,000 years ago. They say that between 50,000 and 60,000 years ago there was a sudden and abrupt change in our DNA which lead to more complex behaviours and ideas like respect, dignity and martyrdom. Some people think that this is when God entered us and created us in his spiritual image.
For those of you familiar with hard disks and USB sticks you can get a terabyte USB stick now for less than $100. The human genome is a total of 4 gigabytes. In my day job as a computer programmer developing firmware for security cameras, I deal with source code repositories frequently about 3 or 4 gigabytes in size. I think modern operating systems like Microsoft Windows and Mac OS are into tens of gigabytes now, approximately 50 or 60 gigabyte.
There's no way that you can do 'corpus callosum' and red blood cells and hemoglobin and 'human chorionic gonadotropin' in 4 gigabytes. So if you want to believe in something Supernatural then just look at a DNA
