Witryna28 cze 2024 · These studies show that many functions of specialized cells in a complex organism are not new. Instead, features and functions seen in single-celled organisms are rearranged in time and space in their multicellular relatives, says Corina Tarnita, a theoretical biologist at Princeton University. WitrynaOther larger organisms such as the larvae of flies, beetles, mites and moths help speed up decay by feeding on dead matter and breaking it down to smaller pieces. This increases the surface area for the bacteria, fungi and molds. Bacteria are considered the “first colonisers” because they are already present in the body before death.
