A. C. Taylor (1999: 204–5) argues that the locations of individual groups have not
changed a great deal, but other changes are massive. In the sixteenth century the
Amerindian societies were much more diversified sociologically than they are now.
There were a number of highly Incanised tribes, such as the upland Jivaroans (cf. section
3.9.1), but also J´ıvaro who lived in small bands in the jungle. There were groups like
the Z´aparo and interfluvial Pano that lived in small units and had no complex social
structure next to large riverside groups like the Conibo and Omagua.
A general issue of considerable interest that needs careful study is the role of the
respective sign languages in the Amazon basin. Nordenski¨old (1912: 315–21) reports
for the Gran Chaco, the border area between Bolivia and Paraguay, that within the mestizo
Spanish communities the deaf had a marginal position while in the Indian communities
they were fully integrated. The reason is the very different status of the respective sign
languages. The Tapiet´e, the example he uses, obligatorily express numbers and measures
through signs, and in their narratives, sign accompanies the spoken word continuously.
All members of the group can use sign with the deaf, and hearing Tapiet´e will often
use sign language among themselves, for example when they want to communicate
silently across a distance. Not all travellers, collectors and researchers were as careful
and unbiased as Nordenski¨old, who provides five pages of description of the Tapiet´e
signs, but reports of gestural communication abound. The reason we cannot deal with
this issue any further is lack of systematic study.
4.1 The Pano–Tacanan languages
The Pano–Tacanan language family is mostly spoken in the Peruvian lowlands, and to
a lesser extent in contiguous areas of Brazil and Bolivia. In Bolivia, Panoan languages
include Ch´acobo, Pacaguara and Yaminahua; and Tacanan languages: Araona, Cavine˜na,
Ese
ejja or Huarayo, Reyesano (a language virtually extinct), Tacana and Toromona.
The Tacanan branch is represented in Peru by Ese
ejja or Huarayo speakers on either
side of the Bolivian border.
The Panoan branch is spread out throughout the eastern Peruvian lowlands and, in
particular, near the Ucayali river basin, with extensions along the Brazilian border both
in the northern department of Loreto and the southern departments of Ucayali and
Madre de Dios. As d’Ans (1970) and Kensinger (1985) explain, there is no consensus
as to which Panoan languages have to be distinguished. Shell and Wise (1971) observe
that speakers of different Panoan languages may partly understand each other but that
Cashibo is not intelligible to speakers of other Panoan languages. Wise (1985) men-
tions the following extant Panoan languages in Peru: Amahuaca, Capanahua, Cashibo–
Cacataibo, Cashinahua, Cujare˜no, Isconahua, Mayoruna, Morunahua, Parquenahua or
Nahua, Pisabo, Sharanahua, Shipibo–Conibo–Shetebo and Yaminahua. The Ethnologue
adds Mayo, which is reported extinct by Wise (1985). Varese (1983) also mentions
