That's why I mentioned the importance of small initial group, which by default means isolation.

Sigh... I'm going to regret this.

Look, you fucking high school drop-out. Get a fucking map of Africa. Find Kilimanjaro on it. Find equator then, it should be right south of it ("below"). Equator is by default the place with highest temperatures, due to the angle between the planet axis and nearest star. In our case - between Earth's axis of rotation and Sun.

Now, what temperature do you need to get snow? Water freezes at 0 Celcius degrees. Snow theoretically can form at 2 Celcius. But as already noted, to form a glacier, you need snow to lie down without melting (simpler words for you) all year round. That means a yearly temperature NOT rising above 0.

Now altitude helps here a lot, since with each 100 meters above sea level, the temperature drops by 0.2 Celcius (usually 0.15). Mt. Kilimanjaro is above 5.5k meters (5.510 to be precise), but surrounding area is at 600 meters above sea level, giving difference of 4900 meters. To simplify things even more, let's just assume 4000 meters of difference. 4000/100*0.15 = 6 degrees and for 0.2 drop of temperature it's 8. Let's take average of 7.

So between the heigh where glacier starts and rest of the area is placed there is a difference of 7 degrees, Celcius.

Thus, by simple equation, when it's 0 degrees at the area with glacier, the flatlands around have 7 degrees Celcius. And this is the absolute minimum situation for the glacier to grow at all. Minimum. The most optimal temperature for glacier growth is at -1.3 Celcius. That would mean the temperature "down below" would be around 6 degrees Celcius

Shall I continue, or you see how fucking chill it was around Kilimanjaro when the fucking glaciers formed?

And this is extremely simplified equation and logic pattern, so your half-dead brain can follow.

This shit is literally taught in elementry school. How early you stopped your education exactly?
