Bøker av Elena Grigorieva

Have you ever wondered how animals and humans on planet Earth evolved from primitive single-celled organisms into the complex animals and humans of today? Elena Grigorieva has used simple pictures and brief descriptions to demonstrate how animals and humans have evolved from single-celled creatures, called protozoans, to multicellular metazoans over aeons of time. This is a key question that scientists and laymen have long puzzled over. This book is particularly useful for young people, schoolgoers and undergraduate students as it describes how the eight predominant bodily systems collaborate.There is rising curiosity about the future of human beings, and the simple answer is that the future of humankind is in the hands of humans. The possibilities are infinite.
