According to this study, it may have had to do with the deactivation (technically known as “pseudogenization”) of an umami taste receptor gene. Umami is the taste that makes things like meat, soy sauce, and mushrooms extra yummy. Apparently, at some point in panda evolution, the umami receptor became non-functional. Based on how much the gene has changed, the authors calculate that this happened around the same time that pandas started eating bamboo. Whether it’s cause or effect is unclear, although the authors think the switch to bamboo may have happened before the gene was lost. Regardless, the loss of the gene reinforced the panda’s vegetarian diet because it made meat less delicious to the bears.
Sorry it's a lot but hope it's useful
<span>These occurs when fetal lose control over the
sphincter and a hypoxia-related peristalsis. Meconium-stained amniotic fluid is
an indication for careful fetal surveillance. The nurse should note the
variable decelerations of the newborn and notify the physician whether meconium
is present. This meconium-stained amniotic fluid are often suction before the
first breath to reduce the severity of the condition. Moreover, amnio-infusion
is an effective way in decreasing the variable fetal heart rate decelerations
and fetal mortality. </span>
