It is estimated that the agriculture was invented 10000 to 12000 year ago. At this period of time, the modern humans or the <em>Homo sapiens</em> were spread to America.
The <em>Homo sapiens</em> begin to form villages and started domesticating animals. Also, all other ancestors of humans were possibly dead up to this period. The agriculture developments and advancements occurred after 10000 year ago.
Hence, the correct answer is <em>Homo sapiens. </em>
A single gene disorder is one that's known to be caused by a single gene. Multiple gene disorders, however, can be caused by multiple gene combinations and other factors. Dominant genes are always expressed in the offspring, while recessive genes are only expressed if the offspring recieves the recessive gene from both parents. Sex-linked genetic disorders occur most often in men, and are caused by a single-gene disorder gene being on the X chromosome but not the Y, so that the offspring needs only one recessive gene to have the trait/disorder.
