Regarding his discoveries, Sir Isaac Newton famously said, "If I have seen further it is by standing upon the shoulders of giants." The Evolving Universe and the Origin of Life describes, complete with fascinating biographical details of the thinkers involved, a history of the universe as interpreted by the expanding body of knowledge of humankind. From subatomic particles to the protein chains that form life, and expanding in scale to the entire universe, this book covers the science that explains how we came to be. This book contains a great breadth of knowledge, from astronomy and physics to chemistry and biology. The second edition brings this story up to date, chronicling scientific achievements in recent years in such fields of research as cosmology, the large-scale architecture of the universe, black holes, exoplanets, and the search for extraterrestrial life. With over 250 figures, this is a non-technical, easy-to-read textbook at an introductory college level that is ideal for anyone interested in science as well as its history.

Sir Isaac Newton famously said, regarding his discoveries, "If I have seen further it is by standing upon the shoulders of giants." The Evolving Universe and the Origin of Life describes, complete with fascinating biographical details of the thinkers involved, the ascent to the metaphorical shoulders accomplished by the greatest minds in history. For the first time, a single book can take the reader on a journey through the history of the universe as interpreted by the expanding body of knowledge of humankind. From subatomic particles to the protein chains that form life, and expanding in scale to the entire universe, this book covers the science that explains how we came to be. The Evolving Universe and the Origin of Life contains a great breadth of knowledge, from astronomy to physics, from chemistry to biology. It includes over 350 figures that enhance the comprehension of concepts both basic and advanced, and is a non-technical, easy-to-read text at an introductory college level that is ideal for anyone interested in science as well as its history.

Maapallon jokainen kolkka kuhisee elämää. Noin neljä miljardia vuotta sitten yksinkertaisista yhdisteistä muodostui sellaista toiminnallista monimuotoisuutta, jota elottomassa luonnossa ei esiinny. Elämän erikoisimmat ominaisuudet ovat sen kyky lisääntyä ja sopeutua. Suuret ympäristömuutokset ovat aiheuttaneet toistuvasti suuria sukupuuttoja, mutta niiden jälkeen elämä on aina noussut uuteen kasvuun ja kukoistukseen. Miljardien vuosien aikana olosuhteiden muutokset ja sukupuuttoaallot maapallolla ovat johtaneet nykyisen lajiston kehittymiseen. Nyt ihmiskunta muokkaa maapallon elinoloja voimakkaasti. Hitaan biologisen evoluution rinnalle on noussut monta kertaluokkaa nopeampi kulttuurievoluutio, joka on tuottanut ulkoisille katastrofeille alttiin teknologisen yhteiskunnan. Mikä on ihmiskunnan ja elämän tulevaisuus maapallolla? Onko ihmisten mahdollista levittäytyä muille planeetoille tai avaruusasemille? Dosentti Kirsi Lehto on astrobiologiaan ja elämän syntyyn erikoistunut kasvivirologi ja kirjailija, dosentti Harry Lehto taas on astrobiologiaan erikoistunut tähtitieteilijä. He molemmat työskentelevät Turun yliopistossa. FT Pekka Janhunen on Ilmatieteen laitoksen tutkimuspäällikkö ja avaruudessa liikkumiseen tarkoitetun sähköpurjeen keksijä.
