SUMMARY
Examining the development of creoles in many parts of the world, Salikoko S.

Mufwene in this book offers unconventional insights into fundamental
principles
of language contact and language change. He questions traditional linguistic

notions like 'system', 'transmission' and adopts biological concepts such as

'ecology', 'competition and selection' to illustrate the similarities
between
languages and viral species and highlight mutual accommodation among
individuals
as a prerequisite for emergent communal behavior. This book shows how the
development of language can be illuminated by using the concepts of
evolutionary
theory. It provides an interesting reading to anyone working in
sociolinguistics
and language contact.

The book collects seven revised versions of previously published articles
since
Mufwene (2001) and three new articles (chapters 4, 6 and 13). Altogether
there
are fourteen chapters divided into three parts: ''Population dynamics and
language evolution'' (Part 1, chapters 2-6), which introduces the
assumptions of
language evolution and the approaches to the study of creoles;
''Competition,
selection, and the development of creoles'' (Part 2, chapters 7-10), which
investigates the mechanisms of structural change in creoles and explores the

similarities and differences in the evolutions of creoles and indigenized
varieties of European languages; ''Globalization and language vitality''
(Part 3,
chapters 11-14), which focuses on globalization and language vitality, and
ends
with a case study of the resilience of Gullah.

In chapter 1, ''Prologue'', the author gives an introduction to the main
topics of
the book, four of which are directly linked to the term 'language
evolution':
structural change, language speciation, language birth and language death.
Definitions of the key concepts like 'imperfect replication', 'invisible
hand'
and 'globalization' are also summarized here. The assumption of the book is
that
the evolutions of communal languages are determined ''not only by the
ecologies
in which they are practiced but also by some of their ontogenetic properties

that make them different from biological species'' (p.2).

Chapter 2, ''Language evolution: The population genetics way'', puts forward
an
analogy between languages and viral species in the sense that both of them
are
parasitic, depending on their hosts' activities and patterns of social
interaction. But unlike viruses which start life with a fully structured
genotype by gene recombination, idiolects develop as individuals learn to
produce increasingly complex utterances with the features copied with
modification. When explaining why a biological approach is adopted, Mufwene
claims that this comparative study between languages and viral species
suggests
''linguistics and biology can very well inspire each other in addressing
evolutionary issues'' (p.28).

In chapter 3, ''Population movements and contacts in language evolution'',
the
author examines the development of the Romance languages and their
non-creole
offspring in Europe and observes that there are the same kinds of shift and
restructuring process as in the evolution of the Romance creoles. He thus
claims
that population movements and contacts motivate language diversification:
inter-idiolectal contact favors different variants from the same feature
pool
and thereby changes the balance of power among competing variants. He also
suggests that the distinction between changes induced by contact and those
independent of contact (cf. Thomason 2001) is misleading because contact is
ubiquitous and it motivates both internal and external change.

Titled ''How population-wide patterns emerge in language evolution: A
comparison
with highway traffic'', chapter 4 compares the dynamics of language
evolution
with the flow of traffic in order to show how patterns have emerged through
the
'invisible hand' and the role of individual speakers as ''unwitting agents
of
change'' (p.59). This comparison originates in Keller (1994) which claims
that
the convergence of behaviors is motivated by the particular ecologies to
which
the individuals respond. Mufwene argues that like traffic, language
evolution
reflects the cumulative actions of individual speakers and the focus on
individuals makes it possible to explain the relationship between population

contact and language varieties.

In chapter 5, ''What do creoles and pidgins tell us about the evolution of
language?'', Mufwene argues that children are not the innovators of new
structures though they do adopt some of the adults' innovations into their
own
idiolects. He then claims that the alleged pidgin ancestry of creoles is
questionable, and structural similarities between expanded pidgins and
creoles
reflect the fact that they were developed by adults using materials from
related
European and substrate languages to meet diverse communicative needs. He
also
suggests that creoles should be compared with the nonstandard vernaculars
spoken
by the European indentured servants with whom non-European labor interacted
regularly, but not with the standard varieties of European languages.

Chapter 6, ''Race, racialism, and the study of language evolution in
America'',
takes on the race-based prejudice in recent linguistic research. In the
analysis
of race and ethnicity in American history, Mufwene argues that race and
segregation can explain the differences between the evolution of creoles and

that of their non-creole kin spoken by populations of European descent. He
also
claims that the reason why African Americans have not been involved in the
Northern Cities Vowel Shift (cf. Labov 2001) is that ''race barriers have
prevented them from socializing (regularly) with European Americans and have

discouraged them from identifying linguistically with members of other
races''
(p.112).

Chapter 7, ''Competition and selection in language evolution'', examines
hybridism
in the development of creoles. The author observes that ''individual
speakers
contribute variably to the communal pool from which the learner draws the
materials for his/her idiolect'' (p.132) to adapt to different ecological
situations, so competition and selection are inherent in the dynamics of
language evolution. He also claims that contact is everywhere and each
language
has been influenced by other languages or emerged from the contact of
several
languages.

Chapter 8, ''Transfer and the substrate hypothesis in creolistics'',
addresses
various versions of the substrate hypothesis of which the biggest problem,
Mufwene points out, is methodological, because most of its claims are based
on
insufficient evidence. As a population-level phenomenon, substrate influence

results from both the recurrence of xenolectal elements in some idiolects
and
their spread within the speech community. Second Language Acquisition
research,
in his view, cannot offer much information about the influence of substrate
elements on the development of creoles since it ''offers nothing that can be

compared to the inter-idiolectal mechanisms of competition and selection
that
led to the emergence of communal norms in creoles'' (p.159).

In chapter 9, ''Grammaticization in the development of creoles'', Mufwene
argues
that grammaticization is one of the restructuring processes that have
produced
creoles by way of extending their lexifiers' constructions to new
grammatical
functions. The recent evolution of creoles highlights the inventiveness of
the
speakers who reuse old patterns to express new meanings. Grammaticization
shows
how the emergent typology may help us to understand ''the way the linguistic
mind
guides structural exaptations to meet the varying communicative needs of
speakers'' (p.178). He also argues that grammaticization need not be
unilinear or
rectilinear, and the investigation of the development of creoles can shed
light
on the study of grammaticization.

With the title ''Multilingualism, 'creolization', and indigenization'',
chapter 10
focuses on societal multilingualism to show that a better understanding of
the
development of creoles and indigenized varieties can clarify the ecological
factors in the evolution of other languages. Speakers interact with each
other
and respond to the immediate communicative challenges by using one variety
or
another. This interconnectedness enables them to produce similar idiolects
which
converge into varieties of a communal language. The author also points out
that
some notions like 'creolization', 'indigenization' show the biases toward
non-European populations and their languages which should be Indo-European
by
genetic classification.

Looking at the history of colonization and economic globalization,
''Language
birth and death'' (chapter 11) discusses the idea that language loss and
speciation are byproducts of colonization, population movement and language
contact. Language birth and death often occur under the similar
socioeconomic
conditions. The real agents of the two processes are speakers who select
particular languages and allow them to thrive, and give up others to let
them
become extinct, so terms like 'killer language', 'linguicide' are misused
because language has no agency in the processes at all. The author also
points
out that there is no way to revitalize some languages and even political
institutions cannot control the factors that have weakened their vitality.

In chapter 12, ''Globalization and the myth of killer languages: What's
really
going on?'', the author argues that colonization brings about both
interconnectedness in a complex system and vitality of languages. The recent

form of globalization differs from the earlier in the speed of communication
and
transportation, and the complexity of its organization, with ''multinational

corporations headquartered mostly in the western world, colonizing Third
World
nations without ruling them politically'' (p.251). He claims again that it
is the
speakers who have opted to speak another language, which leads to the
endangerment of their indigenous languages.

Chapter 13, ''Myths of globalization: What African demolinguistics
reveals'',
examines the development of indigenous languages in South Africa and shows
the
clear connection between language spread and economic development. The
author
argues that the European languages have not always been the ones affecting
indigenous languages since some indigenous languages have also ''displaced
other
indigenous languages especially when they share vernacular functions for the

same populations'' (p.270). Spatial and societal multilingualism do not
necessarily create the situations where one language must prevail at the
expense
of others. It is the new socioeconomic world order and the population
structures
of settlement colonization that determine what language to adopt to deal
with
the changing ecologies.

Chapter 14, ''A case study: The ecology of Gullah's survival'', discusses
certain
ecological factors that have made Gullah stay almost the same since the
nineteenth century and free from debasilectalizing ''by assimilation to
varieties
of English spoken either by descendants of Europeans or by the educated
middle
class'' (p.273). The author argues that Gullah is not endangered by
'decreolization' but by the ecological factors. The sense of linguistic and
ethnic identity has led to the maintenance of Gullah's structural features
and
the economic factors determine how much longer it will be spoken.

EVALUATION
The major contribution of the book under consideration is twofold. First, it

represents a welcome attempt to relate linguistics to biology, thus helping
to
cast new light on our quest to attain a better understanding of how language

really works. The analogy between languages and species originated in its
predecessor, Mufwene (2001), in which the author criticizes the traditional
analogy between a language and an organism and puts forward another one
between
languages and species, and he added in the conclusion ''a language is more
like a
bacterial, Lamarckian species than like an organism'' (Mufwene 2001: 207).
In
this new book, however, he goes one step further to offer a comparison
between
language and viral species, both of which share some properties which are
extremely informative for understanding evolution in both biology and
linguistics. From all these we can see that the author is continuously
trying to
refine his interpretation of language evolution and language contact, which
undoubtedly makes significant contributions to the current linguistic
research.

Second, the empirical support of the book is not exclusively centered on
European exploitation colonies of Africa. In fact, the case studies of
creoles
are from many parts of the world and throughout human history. The
parallelisms
observed between language evolution in England since its settlement
colonization
by the Germanics and that in North America since the European colonization
are
thought-provoking in that they make us question the so-called
''unnaturalness'' of
creoles. So are the similarities found between former European exploitation
colonies of Asia and Africa, and southwestern Europe as a former
constellation
of Roman town colonies. The more we know about the evolution of creoles
around
the world through this book, the more questionable we find some fundamental
assumptions of creoles and language change. However, we cannot deny that
creolization of Middle English (cf. Fennell 2001) is still a controversial
issue
and more empirical backing is needed to justify it.

There are also some shortcomings which would have been remedied through
rigorous
editing, such as the typographical mistake of the word ''sztrong'' (p.123).
The
use of acronyms for some terminologies is also chaotic: the abbreviations
don't
appear at the first mention of the terms and even when they have been given,
in
the following part of the book the terms are written out in full again. For
example, the term 'primary linguistic data' first appears in full (p.18),
and
strangely this appearance is not shown in the subject index; then the
acronym
PLD is mentioned (p.75) but the term is given in full again (p.182). The
term
'language bioprogram hypothesis' has the same problem. Another typographical

problem is 'stammbaum' which sometimes appears italicized (as in p.12, 14,
30)
and sometimes not (as in p.109, 201). One may ask if there is some
difference
between the two forms. And the structure would be much clearer if the
overlap
between some chapters could be reduced, especially in the last part of the
book.

Such shortcomings notwithstanding, this is a fascinating book, challenging
much
received wisdom and packed with innovative analysis of some traditional
linguistic issues. It is a must-read especially for those interested in the
study of creoles and language contact.
