Phrenotopia's video: Alien Biosphere Evolution 2: Building Body Plans

Are humanoid aliens the unavoidable epitome of evolution on all Earth-like planets or can we expect some radically different body organizations of sentient extraterrestrials? In part 2 of the video series on alien evolution, we will be look at the human body plan and any alternative adaptations the animal kingdom on Earth provides. What is the evolutionary and developmental background for the way our different bodies are put together? How can we use these insights for speculative evolution and speculative zoology in an alien biosphere in our worldbuilding projects? Let's find out!
