Branching Off of The Modern Varieties
Most modern varieties can be viewed as descendants of Late Middle Chinese (LMC) of c. 1000 AD. For example, all modern varieties other than Min Chinese have labiodental fricatives (e.g. /f/), a change that occurred after Early Middle Chinese (EMC) of c. 600 AD. In fact, some post-LMC changes are reflected in all modern varieties, such as the loss of the chongniu distinction (between e.g. /pian/ and /pjian/, using Edwin Pulleyblank's transcription). Other changes occurring in most modern varieties, such as the loss of initial voiced obstruents and corresponding tone split, are areal changes that spread across existing dialects; possibly the loss of chongniu distinctions can be viewed in the same way.
Min Chinese, on the other hand, is known to have branched off even before Early Middle Chinese (EMC) of c. 600 AD. Not only does it not reflect the development of labiodental fricatives or other LMC-specific changes, but a number of features already present in EMC appear never developed. An example is the series of retroflex stops in EMC, which developed from earlier alveolar stops followed by /r/, and which later merged with retroflex sibilants. In Min, the corresponding words still have alveolar stops. This difference can be seen in the words for "tea" borrowed into various other languages: For example, Spanish te, English tea vs. Portuguese cha, English chai, reflecting the Amoy (Southern Min) /te/ vs. Standard Mandarin /ʈʂʰa/.
In the case of distinctions that appear to have never developed in Min, it could be argued that the ancestral language did in fact have these distinctions, but they later disappeared. For example, it could be argued that Min varieties descend from a Middle Chinese dialect where retroflex stops merged back into alveolar stops instead of merging with retroflex sibilants. However, this argument cannot be made if there are distinctions in Min that do not appear in EMC, and this does indeed appear to be the case. In particular, Proto-Min (the reconstructed ancestor of the Min varieties) appears to have had six series of stops corresponding to the three series (unvoiced, unvoiced aspirated, voiced) of Middle Chinese. The additional three series are voiced aspirated (or breathy voiced), unvoiced "softened", and voiced "softened".
Evidence for the voiced aspirated stops comes from tonal distinctions among the stops. When voiced stops became unvoiced in most varieties and triggered a tone split, words with these stops moved into new lowered (so-called yang) tone classes, while words with unvoiced stops appeared in raised (so-called yin) tone classes. The result is that the yin classes have words with both aspirated and unaspirated stops, while the yang classes have only one of the two, depending on how the formerly voiced stops developed. Min varieties, however, have both kinds of words in yang classes as well as yin classes. This has caused scholars to reconstruct voiced aspirates (probably realized as breathy voiced consonants) in Proto-Min, which develop into unvoiced aspirates in yang-class words.
In addition, in some Min varieties, some words with EMC stops are reflected with stops while others are reflected with "softened" consonants, typically voiced fricatives or approximants. Such "softened stops" occur in both yin and yang classes, suggesting that proto-Min had both unvoiced and voiced "softened stops". Presumably "softened stops" were actually fricatives of some sort, but it is unclear exactly what they were.
Scholars generally assume that these additional proto-Min sounds reflect distinctions in Old Chinese that vanished in Early Middle Chinese but remained in proto-Min. Until recently, no reconstructions of Old Chinese specifically accounted for the proto-Min distinctions, but the recent reconstruction of William Baxter and Laurent Sagart accounts for both voiced aspirates and softened stops. According to them, voiced aspirates reflect Old Chinese stops in words with particular consonant prefixes, while softened stops reflect Old Chinese stops in words with a minor syllable prefix, so that the stop occurred between vowels. The postulated development of the softened stops is very similar to the development of voiced fricatives in Vietnamese, which likewise occur in both yin and yang varieties and are reconstructed as developing from words with minor syllables.

Famous quotes containing the words branching, modern and/or varieties:
“The moose will, perhaps, one day become extinct; but how naturally then, when it exists only as a fossil relic, and unseen as that, may the poet or sculptor invent a fabulous animal with similar branching and leafy horns ... to be the inhabitant of such a forest as this!”
—Henry David Thoreau (1817–1862)
“Families have always been in flux and often in crisis; they have never lived up to nostalgic notions about “the way things used to be.” But that doesn’t mean the malaise and anxiety people feel about modern families are delusions, that everything would be fine if we would only realize that the past was not all it’s cracked up to be. . . . Even if things were not always right in families of the past, it seems clear that some things have newly gone wrong.”
—Stephanie Coontz (20th century)
“Now there are varieties of gifts, but the same Spirit; and there are varieties of services, but the same Lord; and there are varieties of activities, but it is the same God who activates all of them in everyone.”
—Bible: New Testament, 1 Corinthians 12:4-6.
