It seems that things might change.
The European continent was about to undergo drastic climate change 300,000 years ago. Relatively warm conditions were changing to much colder conditions, a precursor to an ice age. At that time, the sea level on the European continent was on average about 60 meters below its present level, which implies that the Huelva coastline would be 20 to 25 kilometers offshore from its present position.
In other words, the coastal plain was very extensive and probably created by the delta of the river. It was probably covered by water during the wet seasons and totally or partially exposed during the dry seasons. Over this shallow and saline lake environment, made of polygonal ground and microbial covers, that hominids and other fauna trampled. Today, the same kind of polygonal covers are found in extensive areas of marshland in both hot desert and tropical climates.
More or less extensive vegetated areas would be found in the non-flooded areas of this wide coastal plain. Around them, there would be a significant development of dune systems that would move landward from the coast.The environmental context and the landscape have changed in relation to the initial interpretation. The question, therefore, became whether our understanding of who produced these footprints should also change. The answer is to be found in the palaeontological record.
