45. Ethology: Animal Behavior

Página 82

Ethology, one of the most fascinating disciplines in Biology, is the study of animal behavior. This science seeks to understand how animals behave, why they behave the way they do, and how these behaviors have evolved over time. It is a fundamental area of ​​study for those preparing for the Enem, as it is frequently addressed in questions of Natural Sciences.

Animal behavior is influenced by a variety of factors, including genetics, life experiences, environment, and evolution. Ethology is divided into two broad areas: classical ethology, which focuses on innate instincts and behavior, and modern ethology, which considers learning and experience to be important factors in animal behavior.

Classical ethology was founded by Konrad Lorenz, Niko Tinbergen and Karl von Frisch, who won the Nobel Prize in Physiology or Medicine in 1973 for their pioneering studies. They observed that many animal behaviors are innate, that is, they are genetically programmed and occur even in the absence of learning or experience. These behaviors are called instinctive or fixed behaviors. A classic example is the fighting behavior of males of many species to defend their territory or to gain access to females.

Modern ethology, on the other hand, recognizes that many animal behaviors are influenced by learning and experience. For example, many birds learn their songs from other members of their species. Also, many animals learn to find food and avoid predators through past experience. Modern ethology also studies the neural and hormonal mechanisms that underlie animal behavior.

Another important concept in ethology is the ethogram, which is a catalog or inventory of the behaviors of a species. Each behavior is described in detail, including when and where it occurs, how it is triggered, and what its consequences are. The ethogram is a valuable tool for studying animal behavior, as it allows comparisons between different species and helps to identify behavior patterns.

In addition, ethology also studies the animal behavior patterns such as feeding behavior, reproductive behavior, social behavior and escape behavior. Each of these behavior patterns has its own characteristics and is influenced by a combination of genetic, environmental and evolutionary factors.

For example, eating behavior involves seeking out and eating food. This behavior is crucial to the animals' survival and is influenced by a variety of factors, including food availability, the presence of competitors and predators, and the physiological state of the animal.

Reproductive behavior involves a range of behaviors that lead to reproduction, including mate attraction, mating, and parental care. This behavior is influenced by a variety of factors, including partner availability, partner quality and the presence of competitors.

In summary, ethology is a fascinating science that helps us understand animal behavior in all its complexity. It is an essential area of ​​study for those preparing for the Enem, as it is frequently addressed in questions of Natural Sciences. We hope this chapter will give you a solid understanding of fundamental ethology concepts and will prepare you well for the exam.
