Phylum Meaning: Definition, Examples, and Translations
🌿
phylum
[ˈfaɪləm ]
Definition
biological classification
Phylum is a major taxonomic rank used in the biological classification system. It is one of the primary divisions of the kingdom, which groups together organisms that share a fundamental structural framework and evolutionary lineage. Each phylum contains a number of classes, which further categorize organisms into more specific groups. For example, the phylum Chordata includes all animals with a notochord, such as vertebrates. Phyla serve as a crucial hierarchical level in the study of biology and ecology, aiding scientists in the understanding of biodiversity.
Synonyms
Examples of usage
- The animal kingdom is divided into several phyla.
- Phylum Arthropoda includes insects, arachnids, and crustaceans.
- In zoology, phyla are classified based on evolutionary relationships.

Interesting Facts
Biology
- There are about 36 recognized animal phyla, with diverse examples ranging from sponges to mammals.
- The concept allows biologists to understand evolutionary relationships between major life forms.
- The institute of higher education often uses 'phyla' in studies to trace lineage and adaptation.
Evolutionary Biology
- Organisms within a phylum typically share a common ancestor, highlighting the evolutionary history.
- Phylogenetic trees illustrate how different phyla are related, providing insights into evolutionary processes.
- The Cambrian Explosion marked a significant increase in the number of phyla, leading to complex life forms.
Education
- In schools, students learn about phyla as part of studying the animal and plant kingdoms.
- Visual aids like charts comparing characteristics of different phyla enhance understanding.
- Field trips to natural habitats often relate to observing organisms from different phyla in their environments.
Pop Culture
- Animated series often depict characters from various phyla, making biology fun and relatable.
- Documentaries explore the wonders of nature, categorizing living creatures into their respective phyla for viewers.
- Video games sometimes use classification systems akin to phylum, grouping creatures into similar categories.
Origin of 'phylum'
Main points about word origin
- The term ‘phylum’ comes from the Greek word 'phylon', meaning 'race' or 'kind'.
- Introduced in biological classification in the 19th century, it helped organize the vast diversity of life.
- In modern taxonomy, it serves as a key rank above class and below kingdom.
The term 'phylum' originates from the Greek word 'phylon', which means 'tribe' or 'race'. It was first used in a biological context in the 19th century, during a period when the classification of living organisms became more systematic and rigorous. The introduction of 'phylum' allowed scientists to categorize life forms at a higher level than 'class', reflecting their shared characteristics and evolutionary history. The usage of this term has evolved, particularly with advancements in genetics and molecular biology, leading to more precise phylogenetic classifications. Over time, the understanding of what constitutes a phylum has been refined, allowing for more comprehensive studies of biodiversity and evolutionary relationships among organisms.
