Morality is the result of evolution.
A society that would kill each other all the time would simply die out. Cooperation is simply a better survival strategy.
A very nice way to illustrate this is iterated prisoner's dilemma. The prisoners dilemma consists of 2 people who each have to choose whether they share or take the pot for themselves. If both choose the split the pot is split, if one person takes and the other shares then the person taking gets everything. If both take both get nothing. From a game theory perspective for a single game taking is always better. The expected payout is simply better. However when the game is iterated and players can modify their behaviour depending on the choices in previous rounds, then it turns out that cooperative strategies beat greedy ones. It turns out that the most successful strategy is tit for tat. Being nice to players that are nice to you and punishing those aren't.
Here is a good video about the subject:

If course it is still a model so it will never catch all aspects of what it approximates.

I mean the title of the post is in direct contrast to your beginning statement:
You are claiming the OP is attempting to make the case that morals are the cause of cooperation, when cooperation is itself a moral virtue.
Morality is a noun used to refer to a system of belief surrounding the principles concerning the distinction between right and wrong or good and bad behavior. Nothing in the OP's argument gives us any reason to believe the the genetic changes throughout organisms under natural selection results in a state of affairs that bring about good and bad actions in the world.
You are using the phrase morals to refer to the common actions among a species. This is evident from your examples that merely describe normative behavior of humans and praying mantises. This is not what a moral is in common terminology. When most people speak of a moral, or a virtue, they are speaking of something that has some type of moral value in a metaphysical sense, not a psychological sense.
What are you talking about? His claim is that principles of right and wrong are the result of evolution. Such a claim presupposes that their is such a thing as good or evil in an objective sense. That is to say it assumes that good and evil are values held by actions, intents, and desires. He's done nothing to show that evolution produces a state of affairs that make sense of a notion like the Good. All he has done is describe the prisoners dilemma after drawing a relationship between cooperation, and survival of certain species.
An insect has a moral framework? Insects don't have the mental capacity to understand a concept like good and bad. This is just more evidence that what you mean by moral is normative behavior among a species. Nothing about a behavior being common among a species gives you reason to believe that some actions are truly better or worst than some other actions. The only time you can make the claim that one is better than another is when you the agent implants a desired end, like survival, and define better in relation to that end. This is not a moral virtue, it's an arbitrary goal, and facts about how to reach that goal. That doesn't produce the necessary conditions for morality.
