The uncertain case for human-driven extinctions prior to Homo sapiens
J Tyler Faith cs 2020
A growing body of literature proposes that our ancestors contributed to large mammal extinctions in Africa long before the appearance of H.sapiens:
some argue that premodern hominins (e.g. H.erectus) triggered the demise of Africa's largest herbivores & the loss of carnivoran diversity.
Such arguments have been around for decades, but they are now increasingly accepted by those concerned with bio-diversity decline in the present-day, despite the near complete absence of critical discussion or debate.
Here we review ancient anthropogenic extinction hypotheses,
we critically examine the data underpinning them:
arguments made in favor of ancient anthropogenic extinctions are
- based on problematic data & and interpretation,
- substantially weakened when extinctions are considered in the context of long-term evolutionary, ecological & environmental changes:
at present, there is no compelling empirical evidence supporting a deep history of hominin impacts on Africa's faunal diversity.

Inland trout (mountain streams) have higher omega 3 oils than coastal oysters or mussels.

Inland trout (mountain streams) have higher omega 3 oils than coastal oysters or mussels.:-) Yes yes, my little boy, this confirms what we've been saying for ages:
Hn seasonally followed the rivers inland.

Yes, only compete imbeciles believe H.erectus ran after antelopes.

Traditional explanations are that the nose protects against dry air, hot air, cold air, dusty air, whatever air, but most savannah mammals have no external noses, and polar animals such as arctic foxes or hares tend to evolve shorter extremitiesYes, only complete imbeciles believe H.erectus ran after antelopes. https://www.abc.net.au/science/articles/2014/12/04/4140529.htm

Why do humans evolve external noses that don’t seem to serve any useful purpose – our smelling sensors are inside the head. Our nose is vulnerable to damage, and the majority of primates and other mammals manage with relatively flat faces.
The answer isn’t so difficult if we simply consider humans like other mammals.and elephant seals or proboscis monkeys), manipulation of food (in elephants, tapirs and swine), a snorkel (elephants, proboscis monkeys) and as a nose-closing aid during diving (in most of these animals). These mammals spend a lot of time at the margins
An external nose is seen in elephant seals, hooded seals, tapirs, elephants, swine and, among primates, in the mangrove-dwelling proboscis monkeys. Various, often mutually compatible functions, have been proposed, such as sexual display (in male hooded
But what does this have to do with human evolution?coasts, and from there inland along rivers. During the glacial periods of the Pleistocene – the ice age cycles that ran from about 1.8 million to 12,000 years ago – most coasts were about 100 metres below the present-day sea level, so we don’t know
The earliest known Homo fossils outside Africa – such as those at Mojokerto in Java and Dmanisi in Georgia – are about 1.8 million years old. The easiest way for them to have spread to other continents, and to islands such as Java, is along the
If Pleistocene Homo spread along the coasts, beachcombing, wading and diving for seafoods as Polynesian islanders still do, this could explain why Homo erectus evolved larger brains (aided by DHA) and larger noses (because of their part-time diving).This littoral intermezzo could help to explain not only why we like to have our holidays at tropical beaches, eating shrimps and coconuts, but also why we became fat and furless bipeds with long legs, large brains and big noses.
