Inleiding
Dit document is een samenvatting van het boek Biology: A Global Approach, de 12
e druk. Ik ben begonnen van het schrijven van deze samenvatting eind juni 2020 en ik hem deze gebaseerd op de door mij geschreven Nederlandse samenvatting van de 10 e druk. In deze versie van de samenvatting heb ik feedback verwerkt die ik heb mogen ontvangen in de afgelopen jaren dat mijn samenvatting op Stuvia heeft gestaan. Er zit ontzettend veel tijd in deze samenvatting en ik ben trots op het eindresultaat. Ik vraag je dan ook deze samenvatting volgens de richtlijnen van Stuvia te gebruiken en niet te delen met anderen.Deze samenvatting geeft in het Nederlands uitgebreid weer wat er in dit boek beschreven staat. In de samenvatting worden geen afbeeldingen gebruikt (wegens auteursrechten) en wordt er verwezen naar figuren en tabellen uit het boek. Ik raad dan ook aan het boek erbij te houden want, ook al verwijs ik er niet altijd naar, de afbeeldingen ondersteunen de tekst vaak erg goed. Daarnaast laat ik de voorbeelden die in het boek beschrijven staan, (bijna altijd) uit de samenvatting. Deze zijn namelijk door de schrijvers van het boek ondersteunend bedoeld en geven vaak geen nieuwe informatie. De samenvatting kan uiteraard gebruikt worden in combinatie met andere versies van het boek, alleen zal dan de nummering van hoofdstukken, paragrafen, figuren of tabellen niet altijd kloppen.Ik heb de originele Engelse benaming van de hoofdstukken en paragrafen behouden. De rest van de samenvatting is echter volledig in het Nederlands. Deze samenvatting is dan ook een goede ondersteuning voor studenten die het (soms) lastig vinden om door de Engelse teksten in het boek heen te komen.Ik heb een mindmap gemaakt die het overzicht van het hele boek geeft in één afbeelding. Dit helpt je de opbouw van het boek begrijpen. Het eerste hoofdstuk is niet verwerkt in deze mindmap, deze is namelijk overkoepelend voor het hele boek.Ik wens je ontzettend veel succes en plezier met het lezen en bestuderen van deze samenvatting!
