The goal of this paper is to further our understanding of the nature of functional features in Creoles while focusing on how the functional exponent is morphologically realized, assuming a late-insertion-based exoskeletal model in the language mixing scholarly literature. In language mixing, it is observed that words are mixed within a certain syntactic domain (e.g., DP-NP, VoiceP/vP-TP, etc.). For example, in the nominal domain, a determiner D may be from one language, and N (or a stem, e.g., root + categorizer) may originate from another language. Grimstad and Riksem propose that the functional projection FP intervenes between D and N, and both D and F are from one language and N from another language. The phonological exponent of the functional features (e.g., D and F) are assumed to be language-specific (i.e., from one language), subject to the subset principle. Closer to the case that concerns us, Åfarli and Subbarao show that through long-term language contact, functional features can be reconstituted, and the functional exponent can be genuinely innovative. In our study, we propose that functional features can be themselves recombined and that Creole languages can provide evidence for feature recombination either by virtue of their hybrid grammar or through the congruent functional categories they display, using a late-insertion-based exoskeletal model. That is, functional features are not individually inherited from one language or another but can be recombined to form new functional features, allowing a novel functional exponent. To show this, we use synchronic empirical data focusing on the anterior marker -ba from Cabo Verdean Creole (CVC), Manjako (one of CVC Mande substrates), and Portuguese (CVC lexifier) to show how the recombination may operate, as CVC -ba recombines the features it inherited from its source languages while innovating. In sum, the purpose of this study is to show that feature recombination targeting the functional categories of Creole source languages can lead to innovation and that a late-insertion exoskeletal model can best account for the novel functional exponents that result from feature recombination in Creole formation.

In this study, we aimed to evaluate the genetic diversity within and among chicken breeds from the northeast region of Brazil (states of Bahia and Piauí) using microsatellite markers. In addition, we assessed the identity and genetic relationships of chickens from Europe, Africa, and South America, as well as their influence on the formation of the Brazilian breeds. A total of 25 microsatellite markers and a panel containing 886 samples from 20 breeds (including the Brazilian chickens) were used in this study. Different statistical parameters were used to estimate the genetic diversity and relationship among the genetic groups studied. Our study indicates that the Brazilian Creole chickens have high genetic variability. The results show that chickens reared in the states of Bahia and Piauí could have originated from different ancestors. The Brazilian breeds studied have an evolutionary relationship with chickens from Portugal, Nigeria, Chile, and Spain. Our results will contribute directly to the conservation and recognition of Brazilian Creole chicken breeds and provide a solid basis for the demonstration of their genetic identity and genetic conservation of American Creole chicken populations.

The genetic origins and diversity of Creole sheep from five regions of Colombia were investigated based on mitochondrial DNA (mtDNA) variations across 89 sequences from five breeds: one wool Creole sheep (CL) and four hair Creole sheep, including Ethiopian (OPC_E), Sudan (OPC_S), Pelibuey (OPC_P) and Wayúu (OPC_W). A global comparison was done using 62 haplotypes from Iberian, African, Indian, Caribbean, Mexican, Caucasian and European sheep based on sequences retrieved from GenBank. This study aimed to identify the maternal origin of Colombian Creole sheep and their genetic relationships at a global level. The results showed 31 different haplotypes from Colombian Creole sheep, which can be assigned to maternal lineage B, the most common lineage found in European sheep breeds and the only one found in several Iberian breed (e.g., Churra, Spanish Merino) that most likely participated in the Creole formation. Additional analyses showed that wool and hair sheep retained a broad genetic identity despite being geographically separated. The global-level phylogenetic analysis revealed that Colombian Creole sheep belong to a distinct and defined genetic lineage that is likely the result of a founder effect with ecotypes of Iberian descent and the subsequent introduction of foreign breeds. This is consistent with historical reports on the presence of sheep in South America and, particularly, Colombia. Full article
