First of all you cant cite the Answers in Genesis website in a serious science discussion, as they are not a reliable source of science information. Doing so just makes you look silly, and damage your arguement rather than supports it.

However, this discussion here seem to be philosophical in the main. Not being an amoeba I cant say how or why they behave how they do. But the fact is genes dont directly influence behavior. Genes simply code for the creation of proteins, which eveuntually gives rise to a new organism. Other than that I am not well-versed on genetics and molecular biology.

Genes dont determine sex drive. While genes can determine basic hormones level in a given indivdual, often life style or diet, exercise, and social conditioning determines an indiviudal's sexual drive.

This is of course a contentious issue, with no clear answers as to what guide or directs an individual's behavior. It is easy to suggest that a person, for instance, behaves purely according to chemical and electrical chnages in the brain. But this purely mechanist approach seem to be inadequate. How can planned action be explained in this way? One c0uld say no action is planned, just rationalized afterwards. While this may be true on a small scale, humans can create a long temrs plans and goals, and follow through with actions.

So clearly there is somehting in the cognitive loop that acts in some way independent of chemical drives. What might be comonly called free will, or the soul, or the conscious mind--this eneity that is the core of a human being, is so far elusive and unknowable.

Descartes belived that living being like a humanm was composed of two distinct "substances", the everyday physical matter, and a non-physical substance of the soul. And only the non-physcial substance was capable of thought.

While modern science and philopsophy has long since discredited DesCartes material dualism, he may still have been on to something: the consciousness might still be thought of as a non-physical entity. Take for instanee a computer program-- it is not a physical thing in itself, but a sequnce of data. The structure is what is important, not the physcal reality. The human mind likely works in similar way.

So while the brain is composed only of matter, the arrangment of the matter is what makes the magic.
