sponges
They were prokaryotic and anaerobic organisms developed first due to the early environmental condition on earth.

In the early 1970s, the environmental movement succeeded in raising awareness about environmental issues such as pollution and deforestation. This led to the creation of several key environmental laws and regulations, including the establishment of the U.S. Environmental Protection Agency in 1970 and the passage of the Clean Air Act and Clean Water Act in 1970 and 1972, respectively.
Cyanobacteria are the group of organisms most responsible for changing the composition of Earth's early atmosphere. Through photosynthesis, they released oxygen into the atmosphere, fundamentally altering its composition and paving the way for aerobic organisms to evolve.
Earth's oxygen atmosphere was primarily created by early photosynthetic organisms, such as cyanobacteria, which converted carbon dioxide into oxygen as a byproduct of photosynthesis. Over millions of years, these organisms accumulated oxygen in the atmosphere, resulting in the oxygen-rich environment we have today.
Oxygen was the important element missing in Earth's early atmosphere. It was only produced later by photosynthetic 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.
They are called bellwether species, also known as sentinel species.

The early classification system for plants and animals was developed by Carolus Linnaeus in the 18th century. He is known as the "father of taxonomy" for introducing the binomial nomenclature system and grouping organisms based on shared characteristics.
Bioindicator organisms are used to monitor the health of the environment because they can provide valuable information on the presence of pollutants or changes in ecosystem conditions. These organisms are typically sensitive to environmental changes and can serve as early warning signs of potential issues.
The study of how organisms developed is called evolutionary biology. It focuses on how species have changed over time through the process of evolution, which involves genetic variation, natural selection, and adaptation to their environment.
The middle class developed in Northern society in the early 1800s.
All of the early helicopters were developed during WW2
Chemosynthetic organisms help scientists understand how life developed on Earth by providing insights into alternative forms of energy and metabolism that can sustain life in extreme environments. Studying chemosynthetic organisms offers a glimpse into the early conditions of our planet and the potential for life to exist beyond Earth. Researchers can use this information to improve our understanding of the origins and evolution of life on Earth.
During the early modern period of the twentieth century, the synthesizer was developed.
