Ethology is a fascinating part of zoology. It focuses on studying the behavior of animals that are not human. This science helps us understand why animals do what they do.

The ideas for ethology started with Charles Darwin. Later, American and German bird experts in the late 1800s and early 1900s also contributed. Key figures included Charles O. Whitman, Oskar Heinroth, and Wallace Craig. The modern study of ethology really began in the 1930s. This was thanks to the work of Nikolaas Tinbergen from the Netherlands and Konrad Lorenz and Karl von Frisch from Austria. These three scientists even won the Nobel Prize in Physiology or Medicine in 1973 for their important discoveries. Ethology combines studies done in labs and out in nature. It is closely connected to how brains work (neuroanatomy), how living things interact with their environment (ecology), and how species change over time (evolutionary biology).

What is Ethology?

Where Does the Word Come From?

The word ethology comes from ancient Greek language. The word ἦθος (ethos) means "character." The ending -λογία (-logia) means "the study of." So, ethology is literally "the study of character" or behavior. An American entomologist (insect expert) named William Morton Wheeler made the term popular in 1902.

A Look Back: The History of Studying Animal Behavior

Early Discoveries and Key Thinkers

Charles Darwin (1809–1882) was very interested in how animals show their feelings.

Ethologists have always been curious about how animal behaviors change over time. They wanted to know how these behaviors help animals survive and pass on their genes. Charles Darwin was one of the first modern ethologists. His 1872 book, The Expression of the Emotions in Man and Animals, greatly influenced this field.

Early ethologists also looked at behaviors that seem to be "instinctive." These are actions that all members of a species do naturally under certain conditions. Scientists like Charles Otis Whitman and Oskar Heinroth focused on these. They would create an ethogram. This is a detailed list of all the main behaviors a species performs. It also notes how often these behaviors happen. This helped create a clear, factual record of animal actions.

Growing the Field: Nobel Prize Winners

Ethology grew a lot in Europe before World War II. This was largely due to Konrad Lorenz and Niko Tinbergen. After the war, Tinbergen moved to the University of Oxford. This helped ethology become stronger in the UK. Other important scientists like William Thorpe and Robert Hinde also contributed.

As mentioned, Lorenz, Tinbergen, and von Frisch shared the Nobel Prize in Physiology or Medicine in 1973. They received it for their groundbreaking work in developing ethology. Today, ethology is a respected science. It has many dedicated journals like Animal Behaviour and Ethology. In 1972, the International Society for Human Ethology was also created.

Understanding Animals in Groups

In 1972, a British ethologist named John H. Crook pointed out something important. He said that much of ethology had focused on animals as individuals. He believed future studies should look at how animals behave in social groups. Scientists needed to understand the social structures within these groups.

E. O. Wilson's book Sociobiology: The New Synthesis came out in 1975. Since then, studying animal behavior has focused much more on social interactions. This approach looks at how group behaviors help animals survive. It has also led to the field of behavioural ecology. This field studies how an animal's behavior helps it adapt to its environment. In 2020, researchers Tobias Starzak and Albert Newen suggested that animals might even have beliefs.

Niko Tinbergen's Four Big Questions

Niko Tinbergen believed that to truly understand any animal behavior, we need to ask four main questions:

• Function: How does a behavior help an animal survive and have offspring? Why does an animal act this way instead of another?
• Causation: What triggers a specific behavior? How has recent learning changed this response?
• Development: How does the behavior change as an animal grows older? What early experiences are needed for the animal to show this behavior?
• Evolutionary History: How does this behavior compare to similar actions in related species? How might this behavior have started through the process of phylogeny (the evolutionary history of a species)?

These questions work together to give a full picture. They are not separate ideas. Every behavior needs an explanation at all four levels. For example, eating helps an animal get nutrients for survival. But the immediate reason for eating is hunger. Hunger and eating are very old behaviors found in many species. They also develop early in an animal's life. It's easy to mix these up. For instance, someone might say people eat because they are hungry. They might not realize that people feel hunger precisely because it makes them get nutrients.
