The American Journal of Physiology
|June 1, 1984
Summary
Biological similitude explores animal properties to model energy metabolism. A derived mass-independent expression aids comparisons within and between species.
Area of Science:
- Zoology
- Physiology
- Theoretical Biology
Background:
- Understanding animal energy metabolism is crucial for ecological and evolutionary studies.
- Existing models often struggle to account for variations across different body masses.
- The distinction between extensive and intensive animal properties offers a new perspective.
Purpose of the Study:
- To introduce a concept of biological similitude based on animal properties.
- To establish a theoretical framework for modeling the relationship between body mass and energy metabolism.
- To derive a mass-independent expression for energy metabolism.
Main Methods:
- Discussing the distinction between extensive and intensive properties of animals.
- Applying the power function as a mathematical-physical model.
- Analyzing numerical and dimensional constraints of the model.
Main Results:
- A theoretical basis for using the power function to model animal energy metabolism is established.
- A theoretically mass-independent expression for energy metabolism was derived.
- The derived expression offers insights into the relationship between body mass and energy metabolism.
Conclusions:
- The concept of biological similitude provides a novel approach to studying animal physiology.
- The derived mass-independent expression is valuable for qualitative comparisons of energy metabolism.
- This framework can enhance our understanding of metabolic scaling across diverse animal taxa.

01:23Characteristics of Life
Biology is a natural science that studies life and living organisms, including their structure, function, development, interactions, evolution, distribution, and taxonomy. The field's scope is extensive and divided into several specialized disciplines, such as anatomy, physiology, ethology, genetics, and many more. All living things share a few key traits, including cellular organization, heritable genetic material and the ability to adapt/evolve, metabolism to regulate energy needs, the...
02:55The Evidence for Evolution
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.The collection of fossils within sedimentary rocks give a record of common ancestry and often depicts the history of evolution.
01:54Convergent Evolution
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.The structures that arise from convergent evolution are called analogous structures. They are similar in function even if they are dissimilar in structure. Further, structures can be analogous while also...
02:54Evolutionary Relationships through Genome Comparisons
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...
01:24Overview of Anatomy and Physiology
Human anatomy is the scientific study of the body's structures. Some of these structures are very small and can only be observed and analyzed with the assistance of a microscope. Other larger structures can readily be seen, manipulated, measured, and weighed. The word "anatomy" comes from a Greek root that means "to cut apart." Human anatomy was first studied by observing the body's exterior and the wounds of soldiers and other injuries. Later, physicians were allowed to dissect the bodies of...
01:26Pharmacokinetic Models: Comparison and Selection Criterion
Physiological and compartmental models are valuable tools used in studying biological systems. These models rely on differential equations to maintain mass balance within the system, ensuring an accurate representation of the dynamic processes at play.
Physiological models take a detailed approach by considering specific molecular processes. They can predict drug distribution, metabolism, and elimination changes, providing a comprehensive understanding of how drugs interact with the body.
