It has been proposed that species with lower extrinsic mortalities have longer life spans because they can invest in long-term survival (Ricklefs, 2010 Stearns, 1992 Williams, 1957). Maximum life span (MLS) is a fundamental life-history trait related to the rate of aging and senescence in animals. IGF2BP2, which has been reported to simultaneously prolong life span and increase energy expenditure, could be responsible for the evolution of shortened MLS associated with the loss of flying ability. The positively selected mutations detected in IGF2BP2 likely affected the functionality of the encoded protein. Among the 7 genes, only IGF2BP2 is known to affect both life span and energy expenditure.

Although we found no shared genes under selection among all the branches of interest, 7 genes were found to be positively selected in 2 of the branches. Here, we examine the parallel evolution of flight in mammals and birds and investigate positively selected genes at branches where either the acquisition (in little brown bats and large flying foxes) or loss (in Adélie penguins, emperor penguins, common ostriches, emus, great spotted kiwis, little spotted kiwis, okarito brown kiwis, greater rheas, lesser rheas, and cassowaries) of flight abilities occurred. Although ecological factors, such as extrinsic mortality, may lead to either shortened or extended life spans through natural selection, MLS is influenced by complex molecular and metabolic processes, and the genetic changes associated with flying ability that have led to either a longer or shorter MLS are unknown.

So, If you use mods and change elder's lifespan to something else than 10 then the bonus days also change.Acquisition or loss of flying ability is evolutionarily linked with maximum life span (MLS) in mammals and birds. Fun fact: "Long Lived" trait is linked to base elder days i.e.

This trait should follow the same rule by giving 4 times more bonus days in long lifespan than normal and 2 times less in short but the multiplication and division are done twice for some reason. The MCCC would again read "Days Left (10 Including 8.75 Bonus Days)". For example, if in long lifespan and elder has 37 days to live then with "long lived" trait it would be 37 + ((17.5 * 4) * 4) = 317 days.Ī similar thing happens with short lifespan, only there bonus days are divided by 2 twice i.e. I looked at many sims and this calculation holds even when a sim would be given more or less days to live. As you can see, the bonus days are also 4 times more (4 * 17.5 = 70) but actually the bonus days are multiplied by 4 twice and the real calculation is 40 + ((17.5 * 4) * 4) = 320. However, if a sim gets "long lived" trait, the MCCC reads: "Days Left (320 including 70 Bonus Days)". The base number of days given to elders in long lifespan is 40 (4 * 10). "Long lived" trait gives extra 17.5 days according to sim stats in MCCC, showing "Days Left (28 including 17.5 Bonus Days)" (the game seems to round numbers up to integers). It can be a day or two more or less, depending on sim. Now, base number of days elders live is 10. If we take normal lifespan as a basis then every life stage in short lifespan is half of that of normal and long is 4 times longer than normal. So thanks to all the cheats and data the famous MCCC offers I decided to examine this trait.įirst, already known facts. Recently I finally decided to delve into the world of mods to combat many annoyances this game has to "offer".

I've searched through many forums and no-one seems to have an answer to that. I've been wondering for a long time why sims with "long lived" trait just won't die and we end up with big families of old people, basically a retirement home.
