I think the only answer you can give definitely is either "we have both" or "we'll never know".
In psychology we focus on the free will vs determinism debate that expresses the age old question that is whether our behaviour is determined by genes or by ourselves. Honestly, it isn't all that easy to answer. Firstly, we know we have innate behaviours that allow us to hunt and mate etc without getting too weird about it. The idea that I will hunt for food when I am hungry is an innate desire. The chemicals in my brain tell me that hunger is an uncomfortable feeling and thus I attempt to remove it. You (probably) wouldn't criticise a starving man from stealing bread. Perhaps his hand moved by itself. I'm sure in such a situation, your morals go out of the window. However, what makes this debate so hard is the modern system. Whereas millions of years ago a man may steal to stay alive, these days we have punishment systems and, most importantly, a conscience. This is where free will comes in. We can't possibly compare ourselves to animals anymore. As we refuse to eat off anything but a plate or from packaging we believe is clean, and as we seek refuge in homes that can't just be shelter, but must 'look nice', we can't really be compared to even apes. Let's take mating, for example. For the most part, there's a respected system. Although we all have trouble staying still when we see someone that really takes pur fancy, we invite them on a date, charm them and be nice to them until we've.won them over. That element is free will. The more innate option would be the males fight each other until someone wins and yay the ladies taken for like 2 mins until the guys done his bit. And yeah, some idiots still have this mentality, but these days we label them as rapists and shun them. Do you get what I'm saying or is this too far-fetched? Even simple things like manners, for example. Is it innate to hold the door for someone? No, but in countries where it's polite, such as the UK, everyone does it, even if it takes time out of their busy life. That doesn't sound very innate to me, especially as in other countries such as in Asia it isn't done at all. But then again, this is all assuming early humans had no morals at all, which isn't something I can say, but I think I can safely assume. Honestly this response is all over the place but I find this subject really interesting. However I don't have a definite opinion so I'll retail this as a collection of crummy and incomplete ideas.#urwelcome #tldr
