Night Fury Posted March 31, 2020 Share Posted March 31, 2020 I've been watching a video related to how blood began to exist and the person in the video stated, "Human blood for example Has 13 ingredients , if you take each one separately and add them to the mix , you won't get blood. All 13 ingredients have to arrive at the same time. " Is this true? I'll appreciate your response, thank you. Link to comment Share on other sites More sharing options...
Strange Posted March 31, 2020 Share Posted March 31, 2020 As blood has evolved over millions of years of incremental improvement, it is obviously not true. I have no idea what this video is. But it doesn't sound reliable. (And it is a video: officially the second worst medium for communicating detailed technical or scientific information.)

StringJunky Posted March 31, 2020 Share Posted March 31, 2020 It sounds like a creationist argument. Link to comment Share on other sites More sharing options...

Sounds more like H P Lovecraft or Algernon Blackwood to me than a scientific presentation. You should look to more respected sources for example this one Ernest Balwin The Nature of Biochemistry 1967 Cambridge university Press The figures he presents speak for themselves. Interestingly the % of gases in the blood is nothing like the % of gases in the atmousphere. Link to comment Share on other sites More sharing options...

'What was present in nature before blood reached its current state, and how did that function in organisms?' would be a question to ask. One could ask about organisms that don't use blood. One could ask what was the fitness improvement blood provided, and how that changed over time. It is equally true to say that a motorcycle has multiple essential parts, and if you remove one of them you don't have a motorcycle anymore. But remove the engine and you basically have a bicycle. So while you don't have a motorcycle, that phrasing misses the point (perhaps intentionally) that you still have a viable vehicle. Link to comment Share on other sites More sharing options...
