Review of Alien Worlds

Now, I understand we're taking into consideration billions of years of possible life on these planets but we should realize how some of life forms and thus evolutionary trends existed. First off. Fur. Furry animals on earth are a fairly new addition to the history of life when viewed along the whole timeline. It's unlikely that, without the same unfortunate events that befell earth ie the asteroid that wiped out the dinosaurs, furry animals would exist. The asteroid changed the temperature, oxygen levels and other things, making adaption ie growing hair necessary.. things like this took me out of the show frankly. Good effort though
