Summary
Animals do not possess an internal clock for timing. Behavioral studies indicate that temporal regularities in animal behavior do not require an evolved internal clock mechanism.
Area of Science:
- Animal behavior
- Chronobiology
- Neuroscience
Background:
- Animals exhibit orderly behavior when responding to time-sensitive tasks.
- This suggests the potential existence of an internal biological clock for duration perception.
Purpose of the Study:
- To critically evaluate the concept of an internal clock in animals.
- To review experimental data and behavioral observations related to animal timing.
Main Methods:
- Review of existing experimental data from various timing procedures.
- Analysis of observational data on animal behavior in natural settings.
Main Results:
- Different experimental procedures yielded conflicting conclusions regarding the nature of animal timing.
- Behavioral observations outside controlled settings also showed temporal regularities.
Conclusions:
- Evidence does not support the evolution of a dedicated internal clock in animals.
- Animals can exhibit temporal regularities and respond to time demands without an internal clock.

Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing...

The earliest recorded discussion of the basic structure of matter comes from ancient Greek philosophers. Leucippus and Democritus argued that all matter was composed of small, finite particles that they called atomos, meaning “indivisible.” Later, Aristotle and others came to the conclusion that matter consisted of various combinations of the four “elements” — fire, earth, air, and water — and could be infinitely divided. Interestingly, these philosophers...

Dalton was only partially correct about the particles that make up matter. All matter is composed of atoms, and atoms are composed of three smaller subatomic particles: protons, neutrons, and electrons. These three particles account for the mass and the charge of an atom.

An atom comprises protons and neutrons, which are contained inside the dense, central core called the nucleus, with electrons present around the nucleus. Taking into account the wave–particle duality of electrons and the uncertainty in position around the nucleus, quantum mechanics provides a more accurate model for the atomic structure. It describes atomic orbitals as the regions around the nucleus where electrons of discrete energy exist, characterized by four quantum...

The Greek philosopher Democritus proposed that everything on Earth is made up of tiny particles called atomos, Greek for "indivisible," from which the modern term "atom" is derived. In the 19th century, John Dalton proposed the atomic theory that is still largely correct today. He put forth five postulates to explain how atoms made up the world around us. (1) All matter is composed of infinitely small particles or atoms. (2) All atoms of a given element are identical to one...
