Penguins and Ostriches? What's to explain. They're animals with given habitats. They show diversity. And as it happens, the penguin is one of my favorite critters. They're kinda cute and kinda cool at the same time. I don't find that they need much explanation, though there is a great deal written about their habitats and habits so if you're scientifically or otherwise curious, the facts about where they tend to live, what they eat, etc (the scientifically observable) is available to the extent of the research available to now. They live, they eat, poop, walk, breath, etc. The penguine spends much of it's time in the water and has fins that allow it to guide itself through the water in searching for it's food and a beak to catch it's prey with. THe Ostrich I know next to nothing about other than it's a large flightless bird that is somewhat homely but lives, eats, breaths, poops, etc like any other living being. It is interesting. But, not enough to make me run off and study it at the moment.
God created both and designed them for their particular environments. What else do I need to know? I don't think I'll come across either in the near future, although I do have a bazillion Opus stuffed toys on my dresser and TV.
Mom buys them all the time for me and brings them by. LOL
