The reorganization of disarranged embryonic primordia to form an approximation of the “correct” structure by any number of abnormal pathways constitutes a form of goal-directed behavior. One might suppose that such anatomical “goals” are specified by genetic programs evolved through mutation and natural selection to produce useful structures. However, one might also ask the following questions: how can genes direct morphogenesis without specifying the pathways to be followed? How can genetic systems have evolved to specify the organization of the never-before-assembled structures reproducibly generated by abnormal tissue combinations? Experiments have shown that the layered structures generated in such experiments belong to the category of “inherently precise” machines, in which a specific pattern is generated with great precision by the constant repetition of a simple local behavior throughout the pattern-forming system. The organization characteristic of the chordate body plan—the “goal” of early development—also arises by very different developmental pathways in the various members of the phylum. Yet divergent evolution can hardly have altered the mechanisms governing gastrulation and neurulation while holding the end results essentially constant. Evidence suggests that the striking differences in these pathways may be understood less as fundamental alterations of morphogenetic mechanisms than as the physical consequences arising from heterochrony—differences in the times at which a shared set of underlying cellular changes are initiated.","PeriodicalId":100679,"journal":{"name":"Integrative Biology: Issues, News, and Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1999-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/(SICI)1520-6602(1998)1:2<49::AID-INBI3>3.0.CO;2-Z","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89805693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We are vertebrates, within the craniates, within the chordates. Fossils indicate how the chordates separated, in early Palaeozoic times or before, from their latest common ancestor with the echinoderms. The most primitive known fossil chordates retained a calcitic skeleton of echinoderm type (calcichordates) and some of these, the mitrates, were like giant calcite-plated tunicate tadpoles, consisting of a head and a tail with no trunk region. Some mitrates are themselves craniates in the broad sense and represent the ancestral group (stem group) from which extant craniates descended. In this paper, we describe such a stem-craniate mitrate, and reconstruct, from the shared characteristics of the extant craniates supplemented by evidence from fossils, the latest common ancestor of extant craniates which we call “animal x”. (In most respects animal x would resemble a hagfish, but its larva would filter-feed like a lamprey larva.) We then list the changes involved in transforming a mitrate into animal x and describe the probable changes in development in early embryos that converted a mitrate into animal x. During this transition, our ancestors took to swimming forwards rather than crawling rearwards, lost the calcitic skeleton, and acquired the trunk region, the notochordal region to the head, kidneys, and neural-crest cartilage. An important developmental mechanism involved was forward extension of the notochord, caused by anteriorly directed convergent extension movements.","PeriodicalId":100679,"journal":{"name":"Integrative Biology: Issues, News, and Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1999-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/(SICI)1520-6602(1998)1:4<115::AID-INBI2>3.0.CO;2-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74502749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
