animalcules

Animalcules are tiny, microscopic organisms that were first described by the scientist Antonie van Leeuwenhoek in the 17th century. He observed them in various sources, like water and dental plaque, using his handcrafted microscopes. Today, we understand that animalcules include various types of microorganisms, such as protozoa and certain tiny animal forms. While the term is largely historical, it highlights the early discoveries in microbiology, showing how minute life forms exist all around us, often playing essential roles in ecosystems and human health. The study of these organisms has paved the way for advances in biology and medicine.
