Another challenge is to decide when to form a serious relation- ship while one is searching through a sequence of encounters and consortships. Economists and statisticians have developed mathematical models of optimal search that look appropriate. But here again a simple rule can do much better. The standard optimal search strategy is called the 37 percent rule. It is useful when you are looking for the best candidate for a position, and you encounter the candidates one at a time, and you have to offer the position on the spot to the first candidate you like, without going back to previously interviewed candidates. This is somewhat like looking for a long-term mate. The 37 percent rule says that you should estimate how many total candidates are likely to apply for the position, interview the first 37 percent of them, and remember the best out of that initial sample. Then, keep interviewing until you find a candidate who seems even better than that. Once you find that better candidate, stop searching and stick with that one. The trouble with this rule is that the time and energy costs of searching can grow very large if you have a large number of possible candidates. For single New Yorkers, it is infeasible to date 37 percent of Manhattan's population before finding a spouse.

- The mating mind

In our research on mate search strategies, colleague Peter Todd and I found that a rule we call "Try a Dozen" performs as well as the 37 percent rule under a wide range of conditions. Try a Dozen is simple: interview a dozen possible mates, remember the best of them, and then pick the very next prospect who is even more attractive. You do not have to estimate the total number of potential mates you will encounter in your reproductive lifetime; you only have to bet that you will meet at least fifty or so. Humans seem to follow something like the Try a Dozen rule: we get to know a number of opposite-sex friends during adolescence, fall in love at least once, remember that loved one very clearly, and tend to marry the next person who seems even more attractive. Each individual is "satisficing"- looking for someone who is pretty good and good enough, rather than the absolute best they could possibly find. But at the evolutionary level, these satisficing rules impose sexual selection that is almost as strong as the most complicated, perfectionist
decision strategy.

يكلك ال blind mole rat عنده مناعة شبه تامة من السرطان

لأن هذا النوع من الحيوانات يعيش تحت الارض، وبمستويات اوكسجين قليلة، فهو عنده طفرة وراثية بالبروتين p53 حتى خلاياه ميصيرلها necrosis (تموت) بحالات نقص الاوكسجين... بالمقابل هذا البروتين الة وظيفة ثانية هي قتل الخلايا السرطانية اول ما تتكون... وبما انه هاي الوسيلة الدفاعية من السرطان مموجودة، هاي الفئران طورت ميكانزم ثانية هي:

الخلايا تتكاثر بسرعة كلش لحد متوصل حد معين، لما توصل الحد، رح تفرز مادة interferon-beta (IFN-β) اللي حتقتل الخلايا وتقلل عددها (ومن ضمنها الخلايا السرطانية)
