Darwin's observation that bipedalism frees the hand to hold objects led him to hypothesize that tool use was an important selective pressure on bipedalism. True. A recent news article reports on findings from a dig in Mesopotamia. The researchers report that skeletal populations indicate a decline in stature and likely overall health at this period in time. This reminds you of another study you have read about, the populations of St. Catherines Island.
Best Time To Take Pregnancy Test After Missed Period. The best time to take a pregnancy test is one week after the first day of your missed period, as far as medical professionals are concerned. At that point, the levels of hCG in your urine should be more than high enough for your home pregnancy test to detect.
A pregnancy test will detect this hormone about one week after fertilization. Most women tend to wait to take a pregnancy test until after they have missed one menstrual period. If you take a pregnancy test one week after you were supposed to get your period, the result will be about 95% accurate. If you take it too soon after fertilization, it may show up negative when in fact you really are pregnant. Pregnancy test are meant to be considered screening tests. If your test comes up negative, but you are experiencing symptoms of pregnancy you should call your doctor.
