The idea of an extended evolutionary synthesis is to extend the 20th century modern synthesis to include concepts and mechanisms such as multilevel selection theory, transgenerational epigenetic inheritance, niche construction and evolvability—though several different such syntheses have been proposed, with no agreement on what exactly would be included.
Gagasan perluasan sintesis evolusi timbul pada sintesis modern abad ke-20 untuk meliputi konsep dan mekanisme seperti teori seleksi multi-tingkat, pewarisan epigenetik tran-generasional, konstruksi niche dan evolvabilitas—meskipun beberapa perbedaan sintesis semacam itu diusulkan, dengan tanpa kesepakatan tentang apa yang akan diliputkan.
