You need to understand that Chopra sees things from a nondualist perspective. In this view, separation is an illusion and everything is unified. Science is inherently dualist. As such you think biology and physics are separate. But they aren't. All biology is made up of physics. Life apparently evolved from non life. Conscious from apparent non-consciousness. Existence from apparent nonexistence. There is a trend to increasing complexity in the universe, not just entropy, and it's most obviously manifested through life and evolution.

I'm not saying science is wrong. Science (and dualism) provide many useful models to understand existence. But it works by chopping reality up. Into concepts. But our concepts about life are not the experience itself.

I see Chopra's argument as being more metaphorical than literal.
