The modern idea of extinction as a common occurrence in earth's history was first proposed in the early 19th century writings of "Cuvier".
<h3>Who was Cuvier?</h3>
Georges Cuvier, also known as Georges-Léopold-Chrétien-Frédéric-Dagobert, Baron Cuvier, was a French biologist and statesman who founded the sciences of comparative anatomy and paleontology.
Some key features regarding the Cuvier are-
- Cuvier also claimed that the anatomical traits that identify groupings of animals are proof that species haven't yet changed from the beginning of time.
- Each species is so highly coordinated, functionally and architecturally, that it would not be able to withstand considerable alteration.
- He went on to say each species was formed for a certain reason, but each organ for a specific role.
- Cuvier disagreed with fellow colleague Jean-Baptiste Lamarck, whose presented the theory of evolution in 1809, and later with Geoffroy, who provided data relating the evolution of crocodiles in 1825.

Answer:
See image.
Explanation:
This is from my study guide.
The nurse is performing a neurological assessment on a client and elicits a positive Romberg's sign. the nurse makes this determination based on a significant sway when the client stands erect with feet together arms at the side and eyes closed observation.
In order to look for imbalance brought on by a loss of proprioceptive sensory input, Romberg's sign compares equilibrium with the eyes open and closed. When proprioception is impaired, a patient may be able to stand up straight with their eyes open but sways or collapses when they close their eyes.
In order to maintain balance while keeping their eyes open, the patient stands with their feet as close together as possible. In most cases, closing the eyes just temporarily throws balance off. Eye closure increases swaying or outright loss of balance in patients with Romberg's sign deficient proprioception, necessitating a step to reestablish equilibrium and, in rare cases, a near fall. The Romberg sign is a delicate posterior column signal; it is not a cerebellar signal.
