Marc Verhaegen:

... This indicates the overall pattern of vegetation at
Laetoli to have been a mosaic of low & tall deciduous
woodlands & with riverine woodland & forest associations along
water courses.
- Low woodlands would have been dominated by Acacia spp ;
- tall woodlands by Combretum-Albizia spp, with increasing
increments of montane species, such as Croton spp, to the E
of the area.
- Riverine woodlands would have been dominated by
Acacia-Euclea spp, with wetter associations (downriver or
linked with spring activity) supporting gallery forest with
Ficus, Celtis & Croton spp ...
(cf.Dryopith in wet forests + Celtis & Ficus)

Gerrit Hannenberg:

Su, D.F. & Harrison, T. 2007. The paleoecology of the Upper
Laetolil Beds at Laetoli.

On the basis of a detailed and comprehensive comparative
analysis of the mammalian fauna, comparing the ecovariable
structure of the Laetoli fauna with other Plio-Pleistocene
hominin-bearing localities and modern faunal communities, the
paleoecology of the Upper Laetolil Beds is reconstructed as a
"mosaic habitat dominated by grassland and shrubland, with
areas of open to medium-cover woodlands, as well as some
closed woodland and possibly forest along seasonal river
courses." Pp. 279-313 inhttp://www.springer.com/life+sci/zool-
ogy/book/978-1-4020-3097-0

Note, *dominated* by grassland and shrubland, and possibly
forest along *seasonal* river courses. Not wetland at all.

There is hardly any difference between AAT and Conventional
vagueness:

1) Note that both Gerrit and Marc describe the same
environement. Marc just empasizes the aquatic aspects of
the environment. Gerrit empasizes the grasslands aspect.

2) Neither of them is able to explain the selective origins of
bipedalism in animals that still maintained tree-climbing
adaptations.

3) Neither of them is able to explain how these early hominids
survived the dry season and its competitive and predatory
implications.

4) Neither of them has a scenario that provides a gradual
upramp to the development of manipulative abilities

5) Neither of them is able to construct a scenario that
explicates the selective orgins of the social and communal
adaptations (intelligence, culture, cooperation language)
that are the hallmark of humantity.

Don't be fooled by these two Euro-whack jobs. There is hardly
a dimes worth of difference between their respective
positions. All we get from both of them is vagueness. Marc has
vague notions about swimming/ wading and Gerrit has vague
notions about hunting gathering. Both of these notions require
ignorance in their audience and vagueness in their delivery to
survive/avoid scrutiny.
