Antonie van Leeuwenhoek viewed moving objects from pond water under his microscope and named them “animalcules.

Antonie van Leeuwenhoek was a scientist and the first microscopist to observe protozoa and bacteria. He created microscopes that possess a single high-quality lens of small focal length and isolated tiny animalcules (microbes) from various sources such as pond water, well water and rain water. Through his experiments, he also calculated the sizes of the animalcules.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
