Neo-Lamarckian is a term that is largely used in science to refer to the beliefs and theories of French naturalist Jean-Baptiste Lamarck. However, there are a few synonyms for the word that can be used to describe similar beliefs and theories. These synonyms include "acquired characteristics," "biological inheritance," and "soft inheritance." These terms suggest the belief that certain traits and characteristics can be passed down through generations due to environmental factors and personal experiences. While not all scientists agree with these theories, they remain important in understanding the evolution of life on our planet and how changes occur over time.
