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.
Though it is possible that a pregnancy test will detect a pregnancy a couple of days before the start of your period, a false negative is more likely in this time period. Take the test after the time when your period should have started and it will be much more accurate. By 1 week + the test should be positive if you're in fact pregnant.
