I disagree on most of her typological arguments.
Regarding the first set ”Typological similarities with North Pacific Rim languages”, you should first of all go to see how many non-finite verb forms Sanskrit possesses:
https://sanskritstudio.wordpress.com...ples-overview/
https://sanskritstudio.wordpress.com...it-infinitive/
https://sanskritstudio.wordpress.com...nskrit-gerund/
Moreover, my understanding is that PIE did dot use conjunctions either but plenty of nominal forms.
Extensive use of inflectional person marking is also seen in the west, e.g. in Caucasian languages, while in East Asia it is non-existant. To my knowledge personal pronoun roots that contain no semantic feature of person exist only in Nenets where new innovative forms have appeared (2.p. pidər°, 3p. pida). For the rest of the Uralic languages pronoun sets are very similar with IE pronoun sets and reflected on verbal inflection.
Johanna seems to claim that Uralic languages are head-marking, but according to Wals (2 articles written by Johanna herself), Finnish and Hungarian are dependent marking while Nenets is double-marking (
https://wals.info/feature/23A#2/26.1/152.9). From the point of view of the whole-language typology Nenets, Hungarian and Finnish are all inconsistent while Ket and Nivkh and many American languages are head marking (
https://wals.info/feature/25A#2/26.1/152.9). Not much support to her claim.
As for “relatively high frequency of flexible noun-verb roots”, I do not think that this argument is very relevant. Similarly, in European languages verbs are formed from nouns and nouns are formed from verbs. This is pretty universal. Moreover, English is extremely flexible as it uses exactly the same form as a noun and a verb. Noun incorporation in a verb is a more salient feature in the Pacific-Rim languages and it does not exist in Uralic languages.
The argument on “traces of nonaccusative alignment” is not relevant either, because nonaccusative languages pop up here an there (
https://wals.info/feature/100A#2/18.0/149.1) and PIE itself shows very strong indications of ergative pattern.
Regarding the second set ”Typological similarities with Altaic-type”, the first features: “verb-final clauses, noun-final NPs, postpositions, possessor preceding possessed noun, synthetic compounds with the second element as head and primarily or exclusively suffixing morphology (inflectional and derivational)” are seen in the older forms of IE languages as well. These features have often been lost in the west. The following show the order of constituents in a NP in the world languages:
https://wals.info/feature/85A#2/16.3/152.9
https://wals.info/feature/86A#2/21.0/152.9
https://wals.info/feature/87A#2/17.9/144.7
https://wals.info/feature/85A#2/16.3/152.9
Areal patterns are obvious. In this respect, PIE seems to have been different from many Western European languages.
Excluding Ket, all North Eurasian languages are suffixing: (
https://wals.info/feature/26A#2/22.6/152.9). As you see, most IE languages are defined as strongly suffixing as Altaic languages. Usually western Uralic languages do not have a strict word order, although eastern varieties tend to have it. On the other hand, many of you may know how strict word order is in Germanic languages.
Regarding Exponence of Selected Inflectional Formatives (
https://wals.info/feature/21A#2/26.7/152.6), Johanna puts Finnish, Nenets, Russian, German and Greek in the same category of “case+number”, while Khalka, Turkish and Hungarian belong to the category of monoexponential case. Does this justify her claim that Uralic languages are like Altaic languages?
Transparent morpheme boundaries and minimal sandhi only applies to some Uralic languages. However, please take note on what Daniel Abondolo writes:
Because of its polysemy the term agglutinating is best avoided, certainly in connection with Uralic languages, as it is widely used in a variety of crucially different ways. It can be used to imply (1) relatively high levels of segmentability; or (2) of morpheme-shape consistency; or (3) of consistency of morpheme identity with grammatical function. No Uralic language achieves high levels in any of these areas, and many are quite low in two or all of them.

Johanna argues that Uralic and Altaic languages have simple syllable structure, but Wals contradicts her claims (
https://wals.info/feature/12A#2/19.3/152.9) in that most Turkic languages are described as complex as most IE languages while some Uralic and Tungusic languages are defined less complex. If simple onset means no word initial consonant clusters, this feature is quite frequent in the world languages, e.g. in Spanish and Arabic.
In the end, I must say that I do not understand what she means with this: ”Context-free parsing of certain kinds; in particular, minimal or no effects of person hierarchies on the coding or interpretation of combinations of arguments, and minimal lexical classes determining inflectional paradigms”.
As for phonology, I agree that phonological similarities are obvious between Uralic and Altaic languages. However, phonology is usually areal, e.g. Finnish Swedish sounds more Finnish than Swedish.
Johanna is not accurate enough in her arguments. Her claims that are based on the typological arguments above are probably no reliable.
