I think it is the similarities and differences but I could be wrong.
Linnaeus considered a variety of traits when classifying organisms, including physical characteristics such as body shape, structure, and reproductive organs. He also took into account the overall likeness or differences between organisms, as well as their behavior and ecological roles. Linnaeus focused on grouping organisms based on observable and measurable features to organize the diversity of life into a systematic classification system.
Biologists consider the organisms' evolutionary history, genetic similarities, and physical characteristics when classifying them into different groups based on shared traits and ancestry. This classification helps in understanding the diversity of life on Earth and the relationships between different species.
Aristotle studied animals and classified them according to method of reproduction, as did Linnaeus later with plants. Aristotle's animal classification was soon made obsolete by additional knowledge and was forgotten.
Taxonomy is the science of naming and classifying organisms based on their characteristics, while systematics is the study of the evolutionary relationships between different organisms. In other words, taxonomy focuses on categorizing organisms into groups based on their shared traits, while systematics looks at how these groups are related to each other through evolution.

Whittaker's systematics includes ecological factors in addition to morphological characteristics, whereas Linnaeus's system is primarily based on physical similarities. Whittaker's system also accounts for genetic relationships between species, while Linnaeus's system focuses on classifying organisms based on shared physical traits.

Linnaeus primarily used the morphological species concept, which defines species based on their physical characteristics and shared similarities in appearance. He classified organisms primarily based on their observable traits such as size, shape, and color.
Aristotle studied animals and classified them according to method of reproduction, as did Linnaeus later with plants. Aristotle's animal classification was soon made obsolete by additional knowledge and was forgotten.
Scientists needed to expand Linnaeus's system of classification because it initially only accounted for a limited number of organisms and primarily focused on observable traits, which often led to inaccuracies in categorizing species. Additionally, advancements in genetics and molecular biology revealed deeper evolutionary relationships among organisms that were not adequately represented in Linnaeus's hierarchical structure, necessitating a more comprehensive system to reflect these connections.

The category that most similiar organisms belong to is genus.
This is the process of evolution. Organisms develop different traits based on adaptations they need to make for survival. Consider that giraffes developed long necks to reach food from high trees.
