Title: How do bacterial species compete and evolve side by side?
Post by: Tony186 on 15/09/2021 20:16:20
Hey guys, I’m trying to find a paper I once read, is about E coli and the survival of the fittest, more specifically is about a experiment that shows that survival of the fittest might not be completely true under some circumstances, he put two version of E coli in a petri dish, in theory the evolved one should wipe the basic one out, instead they reached a balance where the evolved one has most of the territories but leaved enough for the basic one to survival, I just want to know if anyone seen it some where before, can find it anywhere, Thank you :D

Was it related to the long-term evolution experiment? https://www.nature.com/articles/ismej201769

This study might be related (but is behind a paywall, unfortunately): https://www.nature.com/articles/s41396-020-00810-z

Or perhaps this: https://www.science.org/doi/abs/10.1126/science.175.4027.1272

in theory the evolved one should wipe the basic one out,
That's a strange interpretation of evolution.

Quote from: OP
the evolved one
All living things are evolved.

What matters is:
- Evolved from what?
- Evolved to what?
- In what environment?

One organism may produce more of some enzyme, which helps it digest food quicker
- But that increased enzyme production comes at a cost
- And may actually be a disadvantage under some circumstances (eg where food is scarce)

Biological systems work better when there is a diverse ecosystem, where:
- One organism eats things that others can't touch
- That produces food for other organisms
- And it works in a cycle

You might not think that algae is more advanced than you, but they can "eat" sunlight, and we would be in trouble without them!
 
PS Tony: Please rephrase the title as a question: Select Modify on the original post, and change the title.
