"possible"?? :-D
No, my boy, not even "possible":
Tobias 1995 ³We were all profoundly and unutterably wrong! ? All the
former savannah supporters (including myself) must now swallow our earlier
words ?²
Wood 1996 ³the ?savannah¹ hypothesis of human origins, in which the
cooling begat the savannah and the savannah begat humanity, is now
discredited²
Stringer 1997 ³One of the strong points about the aquatic theory is in
explaining the origin of bipedality. If our ancestors did go into the water,
that would forced them to walk upright ?²
Tobias 1998 ³?Bamford identified fossil vines or lianas of Dichapetalum
in the same Member 4: such vines hang from forest trees and would not be
expected in open savannah. The team at Makapansgat found floral and faunal
evidence that the layers containing Australopithecus reflected forest or
forest margin conditions. From Hadar, in Ethiopia, where ?Lucy¹ was found,
and from Aramis in Ethiopia, where Tim White¹s team found Ardipithecus
ramidus ? well-wooded and even forested conditions were inferred from the
fauna accompanying the hominid fossils. All the fossil evidence adds up to
the small-brained, bipedal hominids of four to 2.5 Ma having lived in a
woodland or forest niche, not savannah.² ³? if ever our earliest ancestors
were savannah dwellers, we must have been the worst, the most profligate
urinators there²
Stringer 2001 ³In the past I have agreed that we lack plausible models
for the origins of bipedalism and have agreed that wading in water can
facilitate bipedal locomotion (as observed in other normally quadrupedal
primates). I have never said that this must have been the forcing mechanism
in hominids, but I do consider it plausible. As for coastal colonisation, I
argued in my Nature News & Views last year that this was an event in the
late Pleistocene that may have facilitated the spread of modern humans.²
Wrangham 2005 ³Here I follow the conventional assumption that hominins
began in the savanna.² ³? the composition of the Okavango as a network of
islands could favor the evolution of bipedalism. For those who envisage
bipedalism as facilitated by the need to traverse or exploit aquatic
environments, an inland delta that generates low islands termitogenically or
hydrodynamically offers rich scenarios.²
Alemseged 2006 ³I believe we should just put the savannah theory aside.
I think they basically became biped while they were living in a wooded,
covered environment ?²
