If happiness is the reason why we endure struggle. What makes little ants not suicidal? What motivates them to bite us and fight! Ants don't feel happiness.what does the objectivist ethics have to say about a mantis who offers it's life to female one o:
On page 931, Galt's speech from Atlas Shrugged states: "An animal is equipped for sustaining its life; its senses provide it with an automatic code of action, an automatic knowledge of what is good for it or evil. It has no power to extend its knowledge or to evade it. In conditions where its knowledge proves inadequate, it dies. But so long as it lives, it acts on its knowledge, with automatic safety and no power of choice, it is unable to ignore its own good, unable to decide to choose the evil and act as its own destroyer."
Ojbectivist ethics only offers this as a contrast to distinguish how man's means of survival differ from the means of survival for plants and animals. Ethics only arises under conditions that include choice or volition. Plants and animals means of survival is automatic. It is their nature to do as they do.
As to the praying mantis, consider the following from Snopes.com: For a long time it was believed that not only did the female praying mantis consume the head (and sometimes the rest) of her mate during copulation, but that this grisly act was a necessary part of the reproductive process. (The reasons given for this act of decapitation included its being a signal to the male to release his sperm, its providing the female with protein required for her to produce more eggs, and its being a way of keeping the male from leaving prematurely.) Even though the notion that the female always eats her mate has long since been disproved, the legend of the always-deadly female persists.
In a research project whose results were published in the journal Animal Behaviour in 1984, entomologists Eckehard Liske and W. Jackson Davis made videotapes of the sex lives of thirty pairs of praying mantises. They discovered that mantises engage in elaborate posturing rituals before mating, but not one of the thirty males had his head eaten during the mating process. They also noted that other scientists had observed the same thing: Although female mantises sometimes ate their mates, the deadly act by no means occurred in every case. The behavior appeared to be influenced by captivity: Female mantises were either jarred into unusually aggressive behavior by the unusual laboratory conditions, or they were simply not fed enough by their keepers.
Yes, the female praying mantis does sometimes eat her mate. In fact, male mantises will often offer themselves up as food to the female during the mating process, and from a biological standpoint this action makes sense: There's no point to mating with a female who might die from a lack of food before she can lay her eggs and pass the father's genes onto the next generation. This doesn't happen all the time, however, and its frequency of occurrence and the reasons for it are still a subject a debate within the entomological world.
