More recent and broader studies have determined that the distinct pottery styles, differing burial practices, different grave goods and the distribution of sites all indicate that the Naqada people and the Nubian A-Group people were from different cultures. Kathryn Bard further states that "Naqada cultural burials contain very few Nubian craft goods, which suggests that while Egyptian goods were exported to Nubia and were buried in A-Group graves, A-Group goods were of little interest further north."[133]
