검증된 단계별 안내1
Understand the concept of a common ancestor: In evolutionary biology, a common ancestor refers to the most recent individual from which all organisms in a group are directly descended.
Identify the groups mentioned: The problem lists plants, choanoflagellates, bacteria, and fungi as options.
Consider the evolutionary relationships: Choanoflagellates are a group of free-living unicellular and colonial flagellate eukaryotes considered to be the closest living relatives of the animals.
Analyze the characteristics: Choanoflagellates share several features with animals, such as similar cell signaling and adhesion genes, which are not found in plants, bacteria, or fungi.
Conclude based on evolutionary evidence: Based on genetic and morphological evidence, choanoflagellates are thought to be the most closely related to the common ancestor of animals, making them the correct choice.
