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.
Fortunately, you no longer have to wait until you miss your period to take a pregnancy test and possibly receive accurate results. There are many pregnancy tests on the market today that allow you to test up to six days before your period is due. However, most tests are accurate about two weeks after possible conception. Note, possible conception could be anytime between about one and five days after sex, depending on when you had sex in your fertile window in relation to ovulation.
