Within the world's Jewish population there are distinct ethnic divisions, most of which are primarily the result of geographic branching from an originating Israelite population, and subsequent independent evolutions. An array of Jewish communities was established by Jewish settlers in various places around the Old World, often at great distances from one another, resulting in effective and often long-term isolation. During the millennia of the Jewish diaspora the communities would develop under the influence of their local environments: political, cultural, natural, and populational. Today, manifestations of these differences among the Jews can be observed in Jewish cultural expressions of each community, including Jewish linguistic diversity, culinary preferences, liturgical practices, religious interpretations, as well as degrees and sources of genetic admixture.
What is another way Jewish cultural expressions stayed the same in each community?
A: unanswerable

In the 1960s, the term bandes dessinees ("drawn strips") came into wide use in French to denote the medium. Cartoonists began creating comics for mature audiences, and the term "Ninth Art"[e] was coined, as comics began to attract public and academic attention as an artform. A group including Rene Goscinny and Albert Uderzo founded the magazine Pilote in 1959 to give artists greater freedom over their work. Goscinny and Uderzo's The Adventures of Asterix appeared in it and went on to become the best-selling French-language comics series. From 1960, the satirical and taboo-breaking Hara-Kiri defied censorship laws in the countercultural spirit that led to the May 1968 events.
