Final answer:
The claim that solitary organisms share their skeletons with many adjoining animals is false, as each solitary organism has its unique skeletal structure.
Step-by-step explanation:
The statement that solitary organisms share their skeletons with many adjoining animals is false. Solitary organisms do not share their skeletons with other animals; each individual has its own skeletal structure. In contrast, lizards and whales may share similar skeleton structures due to evolutionary principles, but they have vastly different habitats and lifestyles. Furthermore, Jacques Monod's statement implies that all living organisms, from simple bacteria like E. coli to complex mammals like elephants, share a common ancestor, which is a foundational concept of evolutionary biology.
One of the strongest arguments for two organisms being closely related evolutionarily is the high homology of their DNA sequences, indicating they share a significant portion of their genetic makeup. This is more indicative of a close evolutionary relationship than mere physical resemblance or sharing the same ecosystem.
