Are there any links for the evolutionary path from before LUCA for animals?🙏
I'm not a scientist just curious? I can't understand how vital bodily systems evolved simultaneously? Excuse my ignorance 😏

Such systems likely evolved gradually rather than at once, which would indeed be quite tricky.
Potential evolutionary paths from simple cells to animals have been proposed - check out this open access paper if you’d like to read more:

OK thanks very much I will.
But if any one critical life support system didn't function then the organism would die. This implies that digestion respiration movement structural support and a nervous system to name but a few were all functional simultaneously.
How could it be otherwise?
Help🙏
🤔👍

These systems have become critical but weren’t when they first emerged - the organisms lived without them or with alternative means for fulfilling their functions. Natural selection for beneficial traits saw the development of these systems & their increasing integration into animal anatomy.

Thanks for your reply but what systems did the first ancestor to the most basic animal have that were alternative to respiration digestion nervous system + all the other critical life support systems for an animal? Isn't it the same problem even with those? Where is the research evidence? 😞
