Which discovery did not contribute to cell theory

Credit for developing cell theory is usually given to two scientists: Theodore Schwann and Matthias Jacob Schneider. While Rudolf Virchow contributed to the theory, he is not as credited for his attributions toward it.

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.
