Ice ages sure do mess with habitats when waters become land-locked and lower the ocean levels; shifting landmasses both above and below the ocean level alter ocean currents which redirect warm and cold waters to different areas; all kinds of creatures have traditional migratory routes walled up or redirected or rediscovered; pole shifting is the magnetic kind rather than the axial kind, which affects Earth's magnetosphere and redirects the sun's radiation according to how this sphere presents itself; and when we have hippopotamus in England, certain creatures dying off, and magnetic fields being laid down in stone, we sure know something wild is going on. But is Earth to blame or is the sun?
Your article offers some good points but certainly having an ice age blocking the Mediterranean from the Atlantic means hippopotamus aren't heading down the Nile and touring the Med, as going beyond is impossible. Unless the hippo are the pygmy kind and in West Africa, which would mean an easy enough walk to follow new kinds of landscapes along new coastlines and eventuate in England, right? Otherwise you'd have to explain how large animals preferring water can climb lots and lots of hills.
Man made constructions having alignments to ancient magnetic poles can't have been built when those poles were located as such, as mankind didn't have the wherewithal to organise themselves into such working parties during times of planetary hardship, especially using antlers and rocks as tools, considering metal working was still a little distant in the future. Magnetic lines laid down in stone stay that way though, right? Would it be easier to accept man sensed the difference in what was beneath their feet against what was north and south? Too easy to understand which birds and creatures are magnetically attuned, and certainly they are the arbiters of which direction is magnetic north/south rather than true north/south...the poles of Earth's axial tilt don't change, do they. Considering there is mention of constructions aligned to ancient pole positions, and how many such possible instances some will aim exactly to where someone can find pretty much anything, is it more likely the odds will find some correlations, and magnetic fields in rock may offer a reason for some directions of what is built above them?
Studies have found certain creatures have died off during magnetic pole drift or flip, which alters sea levels and ice age appearances, and certainly has ocean currents finding new routes in swapping the warm and cold waters as is their nature. While we have a lot of research done into above water crustal shift, we're still exploring the effects of what the ocean beds have contributed to this. New islands form...old islands disappear...shelfs rupture, raise or lower...and if volcanoes contribute to reflecting sunlight away from Earth's surface, we sure can have a snowball effect with waters swapping their heat in new areas and contributing to atmospheric alterations. But we are still pretty much in the dark about the sun's cycles, despite finding evidence of how Earth copes with such...
...which offers what else is affected on Earth by the sun in its 'seasons'? The sun has its own magnetic storms, which Earth does its best to counter, but even our interior can be affected by the sun's magnetism despite our core being very much in control of what it does. We can compare the sun's magnetic fields with Earths in some ways, and even watch magnetic storms wax and wane in differing strengths and reach, and we all know what happens when magnetic fields play with each other...the stronger one tries to alter the other's physical orientation if it can, otherwise the interacting magnetism plays against each other...which brings me to our magnetosphere and its shape and how it redirects the sun's force around us. Do you think there is more chance magnetic polar shift/flip occurs under the sun's influence, or is it all Earth's fault?
Now, tied up in all this is a counterargument by me that mankind was not building things tens and hundreds of thousands of years ago, and yet here we are finding creatures in really weird places which may offer evidence of man making use of such changes, both as food and as effects upon our own migratory habits. In discovering new lands, we would know the feel of them beneath our feet as well as around our ears. Are you sure mankind 'knew' more than we have given them credit for? Or did we just make use of the best possible tools we had...much like Earth makes use of its magnetism and fields to survive the sun?
