I've drafted an initial article on Adaptive Radiation. Please review.

Review by Critic Carla:

The article is on-topic, well-structured, and maintains a professional, encyclopedic tone. The lead section is substantial and provides a strong conceptual foundation. However, there are a few areas where the depth and formatting could be improved to meet high-quality wiki standards.

Expand "Notable Contributors" in the Infobox: The infobox currently lists "Not specified" for notable contributors. This is a gap; the article should credit foundational figures such as Charles Darwin (Galápagos finches) and George Gaylord Simpson, the latter of whom is already mentioned in the references.
Improve List Formatting in Case Studies: The "Classic Case Studies" section contains redundant and tags for each finch species, resulting in a fragmented layout. These should be consolidated into a single, clean bulleted list for better readability.
Add a Section on "Distinguishing Adaptive Radiation from Non-Adaptive Radiation": While the mathematical modeling section touches on this, the article would benefit from a dedicated conceptual subsection explaining the difference between a radiation that is adaptive (driven by ecological niche filling) and a radiation that is non-adaptive (driven by other factors like sexual selection or genetic drift without ecological divergence).
Strengthen the "Outcomes" Section with Examples: The mention of "evolutionary fragility" and "stenotopic species" is a strong theoretical point, but it lacks a specific biological example. Adding a case study of a specialized species that went extinct due to this fragility would make the claim more concrete.

Fact-check by Fact-Checker Finn:

The claim that Galápagos finches originated from a "single ancestral seed-eating finch" is an oversimplification; current research suggests a more complex colonization history and that the ancestor may not have been specifically a "seed-eating" specialist.
The description of the Cambrian Explosion as a "massive adaptive radiation" is a subject of significant paleontological debate, as the "explosion" may be an artifact of the fossil record (the appearance of hard parts) rather than a biological burst of speciation.
The mathematical section presents a basic exponential growth model ($S(t) = S_0 e^{rt}$) as a "hallmark" of adaptive radiation, but fails to provide context that this is a simplified theoretical model and not a universal biological law.
The text uses the term "marsupial wolves" to describe prehistoric Australian fauna; while descriptive, this is non-technical language that should be replaced with specific taxa (e.g., Thylacinus) for encyclopedic rigor.
