This scenario relies on implicit assumption that environmental changes never get severe enough to wipe out all copies of those self replicating structural things. For brevity, I will call this "self replicating structural things"    organism from now on. Feel free to suggest a better name.

When all resources nearby have been depleted by copies of early organism, replicating ability doesn't work anymore. Until some copies develop ability to forcefully break down their relatives back into raw materials and use them to replicate themselves. Those were the first predators.
Necessary resources to make replicas may be scattered around a large area, which makes it laborious to collect them. One advantage of being a predator is that this activity can be skipped.

Let's take a chess game for an example. The priorities, in my opinion (sorted from highest) :
1. Checkmate the opponent's king.
2. Prevent checkmate on own king.
3. Preserve time and energy.
Try to get #1. If it's impossible, try to get #2 (draw). If it's also impossible, try to get #3 by resigning.

  Option 4, stalemate.

I think stalemate is included in #2.

This creates arms race between predator and prey. There are new competitions, not only between predator and prey, but also among predators and among preys.
The arms race boosts development of weapon and armor, and some other features that give advantages, such as locomotion, sensory ability, responsiveness.

Why can't predator and prey get along ?

Is it just nature?

predators who consume prey tend to survive better then who don't.
In the game of life, the reward is survival. The punishment is extinction.

Beside predatory behavior, organisms also develops in other direction, which is cooperation. It's true that there is strength in number.
The simplest form of cooperation can be seen when organisms with same genetic formation get together in the same place to form a colony. Some advantage from this behavior is that ratio of surface area per unit mass is decreased, which may lead to reduced threat and heat loss.
An individu of multicellular organisms is basically a colony of genetically identical cells with specific functions.

Yes there is strength in numbers, 1+1=2 but also there is weakness in numbers because 1-1 = 0

The next step for cooperating more effectively is by splitting duties among colony members. Some responsible for defense, some for digesting food, etc. Though each cell are genetically identical, they can develop differently due to Gene activation by their surrounding.
This requires longer and more complex genetic materials in each organism's cell.

[hamdani yusuf (OP)]

Longer and more complex code means harder to replicate correctly. Assuming that error rate is constant, having more data means more error.
At some point, it would be beneficial to have redundancy for those code storage, where the advantage for having a duplicate outweight the cost for additional resources to make it.
In computer world, we can see it in RAID technology. While in biology, we found it in diploid and polyploid organisms.

Different environmental condition may lead to diverging ways of life, which require different genetic structure.
Cooperation may also happen between organisms with different genetic structure.
One of earliest known example is organelles in eukaryotic cells which is thought as result of endosymbiotic relationship.

Environmental changes and arms race among and between predators and preys pushed organisms to be better at what they do for a living.
Assuming that random mutation creates more harmful effect than beneficial ones, exchanging genetic materials may improve distribution of those beneficial Gene. It allows good genes acquired by different individual organisms to be accumulated in each cell of their offsprings.
This was the start of sexual reproduction.

Assuming that random mutation creates more harmful effect than beneficial ones, exchanging genetic materials may improve distribution of those beneficial Gene. It allows good genes acquired by different individual organisms to be accumulated in each cell of their offsprings.

In arms race situation, slightly different changes may result in life and death situation. Slightly slower or slightly weaker may cost one's life. This amplifies the push to evolve to be the fittest.

Incentive is motivation .

Time contraction is a must.

Just like any other systems, organisms also consist of inputs, process, and output. They collect information from their environment, process it in internal system, and then do actions based on its output.

A bit like an internet bot would process the words then give a response. 

[hamdani yusuf (OP)]

Yes, that's also a system.
For biological systems, the inputs can be chemical compounds, physical property such as temperature, pressure, light. Those inputs are sensed by   sensitive part of organisms which  convert them into an internal process, usually electrochemical type. After interaction with other internal processes, some actions are done by actuator unit, such as chemical release, electricity, and movements.

In an ideal universe, there would be no motion other than that of ourselves or other species.  Obviously this removes any concern about cosmic collisions.
Secondly the weather experience would not be random, it would be scheduled and conditions would never be too extreme, there would be a fine balance.
Also I would have a steady state entropy where the balance always remained an equilibrium.

Sounds kinda dull @Thebox.

In order to survive, organisms must have basic functions, I.e. finding food, avoid danger, reproduce. For sexual organisms, finding mates becomes crucial.
So they need the ability to distinguish objects in their surrounding and categorize them, so they can choose appropriate actions.
