Since then, a number of scientists have used them to justify their own  evolutionary ideas, from neo-Lamarckism to neo-Darwinism, from neutral  evolution to selectionist approaches. Research in recent years has  shown that these fishes are much more complex in their adaptations to  the subterranean environment than previously believed: there are those  with features expected from living in total darkness (complete  blindness and depigmentation) and poor in nutrients (extremely low  metabolic rates); others differ very little, if any, from their  epigean (surface) ancestors in their morphology and physiology (but  not so in their behavior). Some of them even live in nutrient-rich  environments. Actually, one of the most overlooked facets of these  animals is that there are more species of hypogean fishes without  troglomorphisms (blindness, depigmentation) than with troglomorphic  ones. The study of these apparently `unadapted' fishes is providing  new insights into our understanding of the evolution of phenotypic  characters, founding effect, behavioral, and physiological  adaptations. The 86 species of troglomorphic fishes described so far  belong to 18 different families, many of which would hardly fit the  notion that they were 'preadapted' to conquer the underground  environment. Further, many troglomorphic `species' show very little  genotypic differentiation when compared with their putative ancestors,  indicating that massive phenotype changes can be achieved via little  genetic reorganization, a reorganization that mostly affects  regulatory genes. These and many other topics are discussed in this  volume containing 29 papers, written by 41 authors from 9 countries.  Hopefully, this volume will convince many other researchers that  hypogean fishes represent a unique opportunity to study a concept in  evolutionary biology that is only superficially understood: convergent  evolution.\u003c\/p\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Springer\u003c\/p\u003e \u003cp\u003ePublication Date: 2010-12-04\u003c\/p\u003e \u003cp\u003eFormat: Paperback\u003c\/p\u003e \u003cp\u003eISBN-13: 9789048158485\u003c\/p\u003e \u003cp\u003eDOI: 10.1007\/978-94-015-9795-1\u003c\/p\u003e \u003cp\u003eDimensions: 279.0cm x210.0cm\u003c\/p\u003e \u003cp\u003ePages: 376.0\u003c\/p\u003e ","brand":"Springer Netherlands","offers":[{"title":"Default Title","offer_id":44343531045004,"sku":"9789048158485","price":224.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9789048158485.jpg?v=1759288572","url":"https:\/\/lateknightbooks.com\/products\/9789048158485","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
