Summary
Life's origins may involve active environmental regulation by early entities, not just passive responses. This "viability-based behaviour" enhances survival and simplifies the conditions needed for life's emergence.
Area of Science:
- Origins of life research
- Astrobiology
- Biophysics
Background:
- Prevailing theories view early life as passive environmental responses.
- This perspective overlooks potential active self-preservation mechanisms.
Purpose of the Study:
- To propose and define 'viability-based behaviour' as an active regulatory mechanism for early life.
- To explore how such behaviours could precede complex evolutionary processes.
- To reassess the environmental prerequisites for abiogenesis.
Main Methods:
- Conceptual framework development.
- Analysis of empirical data from self-preserving abiological systems.
- Theoretical modeling of environmental regulation in simple entities.
Main Results:
- Viability-based behaviour allows simple entities to adaptively regulate their environment based on internal health.
- This regulation increases survival likelihood.
- These behaviours are sufficiently simple to precede neo-Darwinian evolution.
Conclusions:
- Active environmental regulation by early life forms is a plausible alternative to passive emergence.
- Viability-based behaviour reduces the stringent environmental demands of mainstream abiogenesis theories.
- This shifts focus towards self-organizing principles in the origins of life.

What is Behavior?
9.1K
Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.

The Evidence for Evolution
43.1K
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.

What is Evolutionary History?
37.8K
Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.

Behaviorism
2.3K
The field of behaviorism was pioneered by figures such as Ivan Pavlov, John B. Watson, and B.F. Skinner fundamentally shifted the focus of psychology to the observable and controllable aspects of human and animal behavior. This shift marked a critical evolution in the discipline, emphasizing scientific rigor and experimental methodology.
The core premise of behaviorism is its focus on observable behavior rather than internal thoughts or feelings. This approach argues that true scientific...

Characteristics 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...

Introduction to Biological Bases of Psychology
3.3K
Biopsychology serves as a vital bridge connecting the intricate domains of biology and psychology, shedding light on how biological systems influence psychological phenomena. This field scrutinizes the biological substrates of behavior and mental processes, emphasizing the nervous system along with the roles of neurotransmitters, hormones, and genetics. It also incorporates evolutionary perspectives to explain the adaptive nature of mental functions.
