  In the early 19th century, vitalism was a wibo6 (6;uh- hlraizqf1u3hm /jl j27i -f:xzp cdely accepted theory. This theory suggested that organic u-l1hr x372/f-lpzm joi h c6ia;q 6jufb(hz: compounds, those found in living organisms, could only be produced through a "vital force" present in living matter.

What was the role of urea in falsifying the theory of vitalism?
