The Unity of the Organism, Vol. 1 (Classic Reprint): Or the Organismal Conception of Life: Or the Organismal Conception of Life (Classic Reprint) - Softcover

Inhaltsangabe

Explore how scientists test what makes an organism whole—from the cell to the whole being. This volume surveys early ideas about the unity of life, examining whether cells alone shape the organism or if larger patterns and partnerships matter. It highlights debates on chromatin, cell division centers, and the roles of various cellular parts, using protozoa and plants as case studies. With careful analysis, the book weighs competing theories about how life is organized and regulated.

The text presents key debates in the history of biology, showing how researchers questioned whether the cell is the basic unit of life or if higher levels of organization drive form and function. It considers the evidence for and against aggregation and symbiosis as explanations for how organisms build and maintain their unity.

• Clarifies early cell-theory concepts and how they evolved into modern ideas.


• Describes division centers and centrospheres in protozoan cells, with Noctiluca as a focal example.


• Discusses chromatin’s debated roles in heredity and metabolism, highlighting uncertainties in observation.


• Comparisons of cell-level versus organism-level explanations, including symbiosis and aggregation theories.

Ideal for readers of the history of biology, cell theory, and the physiology of early 20th‑century life science.
