prepositions or dependent words. Then, correct the fragments.
For decades, scholars have argued. About when and how chick-
ens reached the Americas. One theory is that Portuguese and Spanish 
settlers brought them. When they arrived after 1500. Another suggests 
that the chickens were brought over by Polynesian visitors before Colum-
bus’s  voyages. Most scholars once believed that Portuguese and Spanish 
brought chickens to the Americas. Along with seeds, medicinal plants, 
and other necessities. Now, researchers think they fi nally know what hap-
pened. Thanks to some revealing evidence found on the coast of Chile, 
where chicken bones were discovered. Along with some pottery that was 
defi nitely dated between 1304 and 1424, or even earlier. Anthropologists 
performed a DNA analysis on the bones. Which revealed that the chick-
ens from Chile had a close genetic relationship to chickens from several 
Polynesian sites. On the islands of Tonga and American Samoa. When 
these fi ndings were published. Some anthropologists said the discovery 
supports the idea that Polynesians had by that time populated the Pacifi c 
and had even reached the Americas. Though the chicken bones matched 
Polynesian chickens. The pottery found with the bones was of the local 
Chilean style. However, it is still unclear whether it was the local Chileans 
or the visiting Polynesians. Who ate the chickens back then.
Fragments That Start with -ing Verb Forms
An -ing verb form (also called a gerund) is the form of a verb that ends 
in -ing: walking, writing, swimming. Unless it has a helping verb (was walk-
ing, was writing, was swimming), it can’t be a complete verb in a sentence.
