Jellyfish belong to the phylum Cnidaria, which diverged over 500 million years ago, making them one of the oldest multicellular organisms on Earth. They have a simple body structure, primarily consisting of a gelatinous umbrella-shaped bell and tentacles, which has remained relatively unchanged through evolutionary time. The earliest jellyfish-like creatures are believed to have emerged in the Precambrian era, and they have since adapted to a wide range of marine environments. Their evolutionary history highlights the success of their simple body plan and unique reproductive strategies, such as alternation of generations.
the evolutionary history of an animal
The word for an organism's evolutionary history is its phylogeny. Phylogeny represents the evolutionary relationships and history of a group of organisms.
The evolutionary history of a species is often displayed in a phylogenetic tree. This will clearly show the history of the species, which is also known as phylogeny.
The procedure of grouping organisms based on their evolutionary history is called evolutionary classification. It is also called Darwinian classification.
The evolutionary history of an organism is called its ontogeny. This is a study of biology that focuses on the origin of organisms.
Humans are most closely related to chimpanzees in terms of evolutionary history.

Phylogeny.
Phylogenetic classification is based on evolutionary history and relationships among organisms. It organizes species into groups based on shared ancestry and evolutionary relationships, using information from genetic and morphological similarities. This approach helps to study the evolutionary development and relationships among different species.
