Is your house ready for a nuclear attack? http://altaibalancee.today/2OtB2_-HxAnu-lqV3E2nfL-i-1Z_8RId9wddQZo8m9o6mqqY0A http://altaibalancee.today/4KF-JKVJ10BWBM5lWyCVFpo2Jfo8Tblyt_F6Z0djIKpkeExp_Q A choosy mate tends to have preferences for certain types of traitsbalso known as phenotypesbwhich would benefit them to have in a potential partner. These traits must be reliable, and commutative of something that directly benefits the choosy partner in some way. Having a mating preference is advantageous in this situation because it directly affects reproductive fitness. Direct benefits are widespread and empirical studies provide evidence for this mechanism of evolution. One example of a sexually selected trait with direct benefits is the bright plumage of the northern cardinal, a common backyard bird in the eastern United States. Male northern cardinals have conspicuous red feathers, while the females have a more cryptic coloration. In this example, the females are the choosy sex and will use male plumage brightness as a signal when picking a mate b research suggests that males with brighter plumage feed their young more frequently than males with duller plumage. This increased help in caring for the young lifts some of the burden from the mother so that she can raise more offspring than she could without help. Though this particular mechanism operates on the premise that all phenotypes must communicate something that benefits the choosy mate directly, such selected phenotypes can also have additional indirect benefits for the mother by benefiting the offspring. For example, with the increased help in feeding their young seen in Northern Cardinals with more plumage-brightness, comes an increase in the overall amount of food that is likely to be given to the offspring - even if the mother has more children. Though females may choose this trait with the presumed directly advantageous aim of allowing them more time and energy to allocate to producing more offspring, it also benefits the offspring in that two parents provide food instead of one, thereby increasing the likelihood of the overall amount of food available to the offspring despite a possible increase in the amount of offspring sibli ------------------------------ End of alt.music.moxy-fruvous digest V14 #11766 ***********************************************
