The passage states that the east-central United States and southeastern Canada cluster is not nearly as large as the smallest of the Eurasian clusters. This means that it is smaller than all three Eurasian clusters. Since there are four clusters in total (three Eurasian and one east-central United States/southeastern Canada), the east-central United States/southeastern Canada cluster is only one-quarter the size of the total population clusters mentioned.
