Question

The scientific name for humans is Homo sapiens. The name Homo is the to which humans are classified. a. kingdom d. genus b. phylum e. species c. order

Short answer

'Homo' refers to the genus in the scientific name 'Homo sapiens'.

Step-by-step solution

Understand the Linnaean System

The Linnaean system is a way of classifying living things and includes seven primary ranks: kingdom, phylum, class, order, family, genus and species. In a scientific name of any organism, the first part indicates the genus and the second part represents the specific species. In the case of 'Homo sapiens', 'Homo' is the genus and 'sapiens' is the species.

Identify the Correct Taxa

In the scientific name 'Homo sapiens', 'Homo' indicates the genus. From the provided options, it's clear that the correct answer is that 'Homo' belongs to the category Genus.

Key concepts

Homo sapiens

The scientific name for humans is "Homo sapiens." This name is part of the biological naming system known as binomial nomenclature. It is a universally accepted system that allows scientists around the world to understand the precise identification of species. In the name "Homo sapiens," "Homo" is the genus, while "sapiens" is the species. Together, this dual-part name specifies exactly which living organism is being referred to, in this case, modern humans. This naming method avoids confusion by giving each organism a unique, scientific label that can be understood internationally, regardless of language barriers.

Scientific Classification

Scientific classification, also known as biological classification or taxonomy, is a method by which biologists group and categorize species of organisms. The standardized process helps to organize the diversity of life on Earth in a hierarchical structure. In this way, it provides insights into evolutionary relationships and characteristics shared among groups of organisms. A critical part of this system is the linnaean taxonomy, named after Carl Linnaeus, who developed it. His original framework has been adapted and expanded over time but remains largely the basis for today's classification methods. By organizing organisms into a series of ranks, scientists are able to infer relationships and lineage among various life forms.

Genus and Species

In the Linnaean system, each organism is identified by a two-part name, known as its scientific name. This is commonly referred to as binomial nomenclature. - **Genus**: This is the first part of the scientific name and is always capitalized. It denotes a group of species that are closely related and share a common ancestor. - **Species**: The second part of the name is not capitalized. It represents the specific name for the organism, distinguishing it from other species within the same genus. For instance, in the name "Homo sapiens," "Homo" is the genus, and "sapiens" is the species. Together, they allow precise scientific communication about that organism. Both parts of the name are typically italicized or underlined.

Taxonomy Ranks

The taxonomy ranks provide a structured way of organizing all living organisms into hierarchical levels. These ranks range from broad categories to more specific ones. There are seven primary ranks in the Linnaean system:

• **Kingdom**: This is the broadest rank and includes large groups of ostensibly similar organisms.
• **Phylum**: Organisms within a kingdom are further divided into phyla, with each group sharing more specific traits.
• **Class**: This rank narrows down the groups further, focusing on more defining characteristics shared among organisms.
• **Order**: Each class is divided into orders that separate organisms based on finer distinctions.
• **Family**: The order is broken down further into families, grouping species that are more closely related.
• **Genus**: Families are subdivided into genera, consisting of species that exhibit similar characteristics or are genetic relatives.
• **Species**: This is the most specific rank, identifying a single type of organism capable of interbreeding and producing fertile offspring.

Understanding these ranks is essential for classifying and identifying organisms accurately in the scientific community.
