"Through the Tertiary period (from 65 Ma) the Earth's climate became cooler with frequent oscillations that increased in amplitude and led to a series of major ice ages in the Quaternary. Glacial advances and retreats over the Pleistocene resulted in global cycles of contraction, expansion and fragmentation of species ranges resulting in species extinctions, population bottlenecks and differentiation."

Trisomy 21 (nondisjunction) Down syndrome is usually caused by an error in cell division called "nondisjunction."

Sodium intake is important to health and most importantly, it is important to the heart. But excess sodium can lead to serious health issues. Therefore, the intake of sodium should be limited.
As per American Heart Association, an average American consumes more than 3400 mg sodium per day in their food. But the consumption must be limited to 2300 mg.
I am very much surprised to know that I consumed a lot more than this limit of sodium in my daily diet. I take up nearly 200 % of sodium intake. I am surprised by this and very much worried. If I continue to take sodium like this, it will have ill affects on my heart. So, I need to reduce my intake to less than 2300 mg of sodium a day. And also I need to do some cardiovascular exercise regularly.
