What discovery was the Enlightenment scientist Johannes Kepler famous for?

Johannes Kepler is famous for formulating the three laws of planetary motion, which describe the orbits of planets around the Sun. His first law states that planets move in elliptical orbits with the Sun at one focus, while his second law, known as the law of areas, indicates that a line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time. His third law establishes a relationship between the time a planet takes to orbit the Sun and its distance from the Sun, laying foundational principles for modern astronomy. Kepler's work significantly advanced the understanding of celestial mechanics and challenged the long-held geocentric model of the universe.

What idea did Lamarck propose that was rejected?

Lamarck proposed the idea of the inheritance of acquired characteristics, suggesting that organisms could pass on traits acquired during their lifetime to their offspring. For example, he believed that if an organism developed a characteristic through use or disuse, such as a giraffe stretching its neck to reach higher leaves, that trait would be inherited by its descendants. This concept was rejected in favor of Darwin's theory of natural selection, which emphasizes genetic variation and heritable traits rather than acquired characteristics. Modern genetics has further supported the idea that acquired traits do not alter an organism's DNA in a way that can be passed to future generations.
