The selection of infrequent mutations and the inheritance of acquired characters could not alone account for evolution; 2. To admit the selection of small and frequent mutations amongst the explanations of evolution demands the solution of several unsolved problems; 3. The existence of a system of mutations due to imperfect segregation is suggested as one of the possible explanations; 4. The problems to be solved include the appearance of new forms and the bifurcation of species; 5. Infertility between species and facts connected with pure lines have also to be explained; 6. In experiments designed to test this hypothesis natural conditions should be imitated as far as possible.","brand":"Cambridge University Press","offers":[{"title":"Default Title","offer_id":51019611078999,"sku":"9781316633465","price":28.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/1739\/5799\/files\/9781316633465.jpg?v=1750780780","url":"https:\/\/bookcurl.com\/products\/organic-evolution-9781316633465","provider":"Book Curl","version":"1.0","type":"link"}
