26.11. Classification of Living Beings: Classification of living beings in families

The classification of living beings is a fundamental part of the study of Biology. It allows us to understand the diversity of life that exists on our planet, as well as the evolutionary relationships between different species. In the context of the Enem, it is important to have a solid understanding of this classification, especially with regard to the classification of living beings into families.

What are families in biology?

In taxonomy, the science of classifying living things, a family is a level of classification that groups together several related species. It is a taxonomic category that is above genus and below order. For example, the Felidae family includes all cats, from the domestic cat to the lion and tiger.

How are families named?

Families are usually named using the name of the most representative genus, followed by the suffix "-idae". For example, the dog family is called Canidae, a reference to the genus Canis, which includes the domestic dog and the wolf.

How are families determined?

The determination of families is based on a variety of characteristics, including physical, behavioral and genetic characteristics. Taxonomists examine these features and use them to group related species. However, it is important to note that classification is an ever-evolving science, and new discoveries can lead to changes in the way species are classified.

Examples of families

There are many different families in biology. Here are some examples:

• Felidae: This family includes all cats, from the domestic cat to the lion and tiger.
• Canidae: This family includes all dogs, from the domestic dog to the wolf.
• Hominidae: This family includes all the great primates, including humans, chimpanzees, gorillas, and orangutans.
• Rosaceae: This family includes many flowering plants, including roses, strawberries, apples, and pears.

Importance of classification in families

Classification into families is important for several reasons. First, it helps us understand the evolutionary relationships between different species. Second, it provides a systematic and organized way of naming and classifying the enormous diversity of life on our planet. Third, it provides a framework for the study of biology, facilitating research and learning.

In summary, the classification of living beings into families is an essential part of the study of Biology. It allows us to understand the diversity of life that exists on our planet and the evolutionary relationships between different species. For the Enem, it is crucial to have a solid understanding of this classification.
