The article "Secrets of Metamorphosis: Why Some Animals Transform" from BBC's Discover Wildlife explains why certain animals undergo dramatic changes while others retain the same form throughout life. Evolutionary biologist JV Chamary explores the biological and ecological advantages of metamorphosis.

The article "Could Fire-Breathing Animals Really Exist?" from BBC Science Focus discusses the scientific plausibility of fire-breathing animals, inspired by the dragons in House of the Dragon. Evolutionary biologist Henry Gee explains how certain chemical reactions and fire-resistant materials could theoretically enable an animal to breathe fire.

The article "Animals evolve larger limbs to adapt to rising temperatures" from BBC Science Focus discusses how climate change is prompting warm-blooded animals to develop larger appendages, such as ears, beaks, and limbs, to better regulate body heat.

The article "Birds and Reptiles Cry Tears Like Humans" from Science Focus explains how the tears of birds and reptiles contain similar chemical compositions to human tears. Scientists hope this research will lead to improved treatments for eye conditions and offer new insights into evolutionary biology.
