- 1864 — Louis Pasteur disproved the spontaneous generation of cellular life.
- 1865 — Gregor Mendel demonstrated in pea plants that inheritance follows definite rules. The Principle of Segregation states that each organism has two genes per trait, which segregate when the organism makes eggs or sperm.
