Verified step by step guidance

Understand the historical context: Before the 19th century, the prevailing belief was that organic compounds could only be synthesized by living organisms. This was known as the theory of vitalism.

Recognize the concept of vitalism: Vitalism posited that organic compounds were fundamentally different from inorganic compounds because they were thought to contain a 'vital force' exclusive to living beings.

Identify the shift in understanding: The work of scientists like Friedrich Wöhler, who synthesized urea from inorganic compounds in 1828, challenged the idea that organic compounds required a living organism for their formation.

Connect to broader scientific developments: The shift away from vitalism was part of a larger movement in science during the 19th century, which included the work of Charles Lyell in geology and Charles Darwin in biology, emphasizing natural processes and evolution.

Summarize the historical belief: Prior to these scientific advancements, the belief was that organic compounds could only be synthesized by living organisms, reflecting the influence of vitalism in scientific thought.
