I NEED HELP AND I AM BEING TIMED HELP I WILL GIVE YOU A CROWN how did the climate influence the arrival of the first humans in the americas?

Climate explains a higher proportion of extinction rates . This shift in R2 indicates that the ability to disentangle the relative influence of climate vs. humans is highly sensitive to selection of human arrival dates, rather than robust to dating uncertainty as Prescott report, even at the coarse temporal resolution used. This sensitivity is likely a result of close synchrony between human arrivals and megafaunal extinctions, so that modeling extinction peaks with less plausible arrival scenarios results in detection of a larger climatic influence . This effect is increasingly evident when multiple less plausible scenarios are simultaneously considered, yielding climate as by far the strongest predictor of global extinction rates.

facts: the 14th amendment

the 14th amendment addresses citizenship rights and equal protection of the laws.

the 14th amendment was approved by congress in june of 1866 and ratified by the states on july 9, 1868.

the 14th amendment establishes that all persons born in the united states are citizens and are guaranteed all the rights of citizenship.

the 14th amendment establishes that the law protects all citizens equally.
