Here is a possible concise summary:
This is a transcript of a video that explains the concept and types of metamorphosis in animals, such as insects, amphibians and fish. It gives examples of how different species change their form, behavior and strategy as they grow from eggs to adults. It also introduces the host of the video, who is a zoologist and author, and promotes a Skillshare course on storytelling. The video ends with a question about human growth.
Here are the key facts extracted from the text:
1. Metamorphosis is when one thing becomes another and it is demonstrated by over 65% of all animal species on earth, mostly insects.
2. Insects can undergo incomplete or complete metamorphosis, which have different stages and degrees of change from egg to adult.
3. Complete metamorphosis involves four distinct phases: egg, larva, pupa and adult, each with a specific purpose and function.
4. Some insects, such as butterflies and moths, can remember things from their larval stage after their metamorphosis, which suggests that parts of their nervous system have continuity through their radical body change.
5. Amphibians and some fish also undergo metamorphosis, which is controlled by a single hormone called thyroxine.
6. Metamorphosis allows animals to exploit different niches and resources, and adapt to changing environments.
7. The text is an episode of Animal Logic Second-Nature, hosted by Jess Keating, a zoologist, illustrator and author who recommends Skillshare for learning writing skills.
