The first organisms to develop a hardened endoskeleton were likely ancient invertebrates called echinoderms, such as sea urchins and starfish. Their endoskeleton is made of plates composed primarily of calcium carbonate. This adaptation provided structural support and protection as these organisms evolved to live in various marine environments.

Probably Protista, because there are evidences that suggests they were the first eukaryotes to be developed.
What was the first classification system and who was the person developed the classification system
Cloning DNA was invented by Paul Berg in 1972. He developed the first recombinant DNA molecule using genes from different organisms.
Simple prokaryotic organisms, such as bacteria and archaea, are believed to have been the first to develop on Earth due to the harsh early environmental conditions, like the lack of oxygen and extreme temperatures. These organisms were able to thrive in such conditions and are thought to have played a crucial role in shaping the Earth's early environment.
Simple, single-celled organisms like prokaryotes, such as bacteria, likely developed first due to the early environmental conditions on Earth. These organisms were able to thrive in the primitive, harsh conditions of early Earth and played a significant role in shaping the planet's biosphere.
The person who first developed a somewhat crude method of classification for organisms was Carolus Linnaeus. He is known as the "Father of Taxonomy" for his work in developing the binomial nomenclature system in the 18th century.
Carolus Linnaeus developed the first widely accepted system of biological classification. He classified organisms into two groups - plants and animals - based on their physical characteristics.

The first formal system of classification of organisms was developed by Carl Linnaeus in the 18th century. He introduced the binomial nomenclature system, which assigns each species a two-part Latin name consisting of the genus and species. This system laid the groundwork for modern taxonomy and is still in use today for naming and classifying living organisms.
The very first volleyball was made from toothpaste hardened.
The first organisms to appear on Earth were likely single-celled microorganisms such as bacteria and archaea. These organisms emerged around 3.5 - 4 billion years ago in a primordial soup of chemicals and developed into more complex life forms over time.
Aristotle was the Greek philosopher who developed the first system for classifying living things. He used a system of organizing organisms into a hierarchical structure based on their physical characteristics.
Probably Protista, because there are evidences that suggests they were the first eukaryotes to be developed.
