"Bathmic" is a term derived from the field of evolutionary biology and it refers to the concept surrounding the gradual and steady change or progression in the ability or complexity of an organism over time. The term originates from the Greek word "bathmos," which means a step, grade, or course. In this context, "bathmic" describes the measure or scale of development or advancement within an organism.
The term "bathmic" is often used to describe the evolutionary changes that occur within species, populations, or individuals as they adapt to different environments or undergo genetic modifications. It emphasizes the idea of a continuous process, wherein organisms undergo gradual transformations in order to improve their fitness, survival, and adaptability to changing conditions.
The concept of "bathmic" poses a contrast to the notion of saltation, which implies sudden and large-scale changes or jumps in evolution. Bathmic changes are gradual and accumulate over time, often resulting in variations in physical traits, behavior, or reproductive strategies. This term is frequently used in conjunction with terms like "bathmic speciation" or "bathmic evolution" to describe the ongoing, step-by-step process of change and adaptation in living organisms.
Overall, "bathmic" is a term employed in evolutionary biology to describe the gradual, incremental changes that occur within organisms as they adapt and evolve to new circumstances, allowing them to better survive and reproduce.
