Llamas in 21st CENTURY North America have evolved into a number of distinct types based on:

• Genetic resources inherited from thousands of years of selection for distinct types of lama by indigenous cultures of South America.
• The genetic resources inherited from importations throughout and especially the latter part of the 20th century;
• Selection preferences and strategy beginning in the mid to late 1970's until the present.

The variations in coat type humans have selected for remains the most prominent feature distinguishing types of llama from one another. Much of the early 20th century population of llamas in North America were shorter coated but by the mid '80's, selection criteria initiated the re-development of a spectrum of phenotypes differentiated by distribution, length and quality of fiber. The term "Classic" began to be used as a generic label for llamas with short body fiber and little or no wool on head, ears and legs, who had a distinctly different appearance compared to the longer fibered types.

The evolution and refinement of a short and functional coat type clearly distinguishes today's Classic Llama. The Classic llama has emerged as a measurably distinct phenotype that can be reliably reproduced. The term "Classic" is now in use internationally to identify this distinct llama breed type.

The fundamental attributes that most clearly identify a Classic llama include:

• Are notably sparse-coated (not dense);
  

• Short neck wool often with a distinct "mane" of guard hair:

It is important to note that these attributes define not only a distinct visual appearance but also a uniquely functional coat type. Ample coarse guard fiber has dual benefits. Guard fiber naturally sheds debris and makes the Classic coat easy to groom and maintain. The guard fiber also allows for efficient thermal regulation. A coarse guard fiber is thicker and requires significant skin surface area for support, preventing the simultaneity of a dense undercoat and it's natural felting process which inhibits thermal transfer and makes grooming next to impossible. Study has shown the Classic coat superior for keeping llamas cooler during the hot months and in working situations. Ample coarse guard hair also protects and insulates against the cold and wet (becoming an essential attribute for packers when unexpected snow or freezing rain occurs.) The functional Classic coat type combined with an athletic body provides a "complete package" for any sport or work requirements.

In the tradition of their ccara ancestors, Classic llamas are associated with superior strength, endurance and athleticism for packing, driving and other athletic activities. Classic llamas come in different sizes and shapes. Some prefer tall llamas while others prefer shorter llamas. Within the range accepted as normal for a llama, height is not a critical factor for superior athletic function nor for distinguishing classic llamas from other types.

Athleticism and endurance involve a complex arrangement of proportionate structural elements. Different proportions between parts can compensate to produce strong efficient motion, the result being different appearing body types that can be equally superior for athleticism and endurance. Athletic ability is best assessed by watching llamas in motion and ultimately through use within the contexts of specific work/sport/companion activities.

Many if not most breeders of Classic llamas select for athleticism. It is important to note that what distinguishes a superior athlete involves qualities in addition to what distinguishes a llama as Classic. Athleticism and related conformational attributes, although essential for qualifying any llama as superior for function and to help individuals remain structurally sound over time, is not a fundamental factor for distinguishing Classic or other breed types from one another.

Breeders of athletic and working llamas select individuals according to a variety of factors based on perception of quality and working requirements. It is recommended that those seeking quality athletes and companions explore the spectrum of differences and preferences found on different farms in order to make an informed choice and find llamas that best suit particular indivivual needs.
