However, new species are being discovered all the time. Some of those recent additions are shown here. The sneezing monkey, Rhino-pithecus strykeri, was discovered in northeast Myanmar. While very rare, it is easy to locate in the forest, since it sneezes when it rains. Not all new species are rare—some have simply remained isolated from human contact, such as the Nepalese autumn poppy Meconopsis autumnalis , which lives only at elevations about 10, feet in the Himalayas.
As we will learn in this chapter, although life is diverse, it also shares a number of important characteristics. As you read through this chapter, think about the following questions: 1. What are the general characteristics that separate life from nonliving things?
What are some of the challenges facing science today? Learning Outcomes Upon completion of this section, you should be able to 1. Explain the basic characteristics that are common to all living organisms. Distinguish between the levels of biological organization. Summarize how the terms homeostasis, metabolism, and adaptation all relate to living organisms.
As we observed in the chapter opener, life is diverse Fig. Life may be found everywhere on the planet, from thermal vents at the bottom of the ocean to the coldest reaches of Antarctica. These characteristics include levels of organi-zation, the ability to acquire materials and energy, the ability to maintain an internal environment, the ability to respond to stimuli, the ability to reproduce and develop, and the ability to adapt and evolve to changing conditions.
By studying these characteristics, we gain insight into the complex nature of life, which helps us distinguish living organisms from nonliving things. In the next sections, we will explore these character istics in more detail. The complex organization of life begins with atoms, the basic units of matter.
Atoms combine to form small molecules, which join to form larger molecules within a cell, the smallest, most basic unit of life. Although a cell is alive, it is made from nonliving molecules Fig. The majority of the organisms on the planet are single-celled.

Informed by extensive research on how people read, think, and learn, Revel is an interactive learning environment that enables students to read, practice, and study in one continuous experience — for less than the cost of a traditional textbook.
A modular, manageable, meaningful survey of the life span Revel Discovering the Life Span provides a broad overview of the entire range of the human life, from the moment of conception through death. Utilizing a flexible, modular organization, author Robert Feldman covers the life span chronologically and focuses on physical, cognitive, and social and personality development within each stage of life.
In order to provide an up-to-date snapshot of the discipline, the Fourth Edition includes hundreds of new citations as well as coverage of a number of engaging contemporary topics. Learn more about Revel. Dynamic content designed for the way today's students read, think, and learn brings concepts to life Integrated within the narrative, interactives and videos empower students to engage with concepts and take an active role in learning. Revel's unique presentation of media as an intrinsic part of course content brings the hallmark features of Discovering the Life Span to life.
Revel's media interactives have been designed to be completed quickly, and its videos are brief, so students stay focused and on task. Located throughout Revel, quizzing affords students opportunities to check their understanding at regular intervals before moving on.
The Revel mobile app lets students read, practice, and study — anywhere, anytime, on any device. Content is available both online and offline, and the app syncs work across all registered devices automatically, giving students great flexibility to toggle between phone, tablet, and laptop as they move through their day. The app also lets students set assignment notifications to stay on top of all due dates.
Self-paced Journaling Prompts throughout the narrative encourage students to express their thoughts without breaking stride in their reading.
Assignable Shared Writing Activities direct students to share written responses with classmates, fostering peer discussion. And Essays integrated directly within Revel allow instructors to assign the precise writing tasks they need for the course. Highlighting, note taking, and a glossary let students read and study however they like. Educators can add notes for students, too, including reminders or study tips.
A modular approach makes lifespan development manageable and meaningful The book uses a modular approach to optimize student learning. Each chapter is divided into three modules, and in turn each module is divided into several smaller sections. So rather than facing long, potentially daunting chapters, students encounter material that is divided into smaller, more manageable chunks a structure that psychological researchers long ago found to be optimum for promoting learning.
In addition, this modular approach offers instructors more flexibility in how they assign text material, enabling them to easily highlight their preferred theoretical or topical approach to lifespan development. In a unique departure from traditional lifespan development texts, each chapter integrates the physical, cognitive, and social and personality domains within each chronological period.
Chapters begin with a compelling story about an individual representing the age period covered, and chapters end by refocusing on that individual and integrating the three domains.
Designed to be user friendly and written in a direct, conversational voice, the text replicates a dialogue between author and student as much as possible. Author Robert Feldman crafted the text to be understood and mastered by students of every level of interest and motivation.
Student-focused content and pedagogical tools boost understanding and retention Chapter-opening prologue s tell the story of an individual who is at the developmental stage covered by the chapter. The material in the prologue sets the stage for the chapter, and the prologue is revisited at the end of the chapter when the physical, cognitive, and social and personality aspects are integrated.
Module-opening vignettes describe an individual or situation that is relevant to the basic developmental issues being addressed in the module. Learning objectives at the beginning of every subsection clearly specify what students are expected to master after reading and studying the material. From Research to Practice boxes in each chapter describe current developmental research or research issues, applied to everyday problems.
Topics discussed include about preschools around the world, gay and lesbian relationships, the marketing of cigarettes to the less advantaged, and race, gender, and ethnic differences in life expectancy. Becoming an Informed Consumer of Development features present information on specific uses that can be derived from research conducted by developmental investigators. For instance, the text provides concrete information on how to encourage children to become more physically active, how to help troubled adolescents who might be contemplating suicide, and how to plan for a good retirement.
A running glossary helps students stay on top of key terms, which are defined in the margins of the page on which they are presented. At the end of each chapter, the chapter-opening prologue is recapped and addressed from the three domains of physical, cognitive, and social and personality development.
In addition, questions about the prologue are posed from the perspective of people such as parents, professional caregivers, nurses, and educators. New and updated material keeps the text current and engaging NEW! The Fourth Edition offers expanded and new coverage of advances in areas such as behavioral genetics, brain development, evolutionary perspectives, and cross-cultural approaches to development.
Hundreds of new citations have been added, mostly from articles and books published in the last few years. Contemporary topics have been incorporated into every chapter. This clear, detailed schedule helps students stay on task by eliminating any ambiguity as to which material will be covered during each class. When they understand exactly what is expected of them, students are better motivated to keep up.
Actionable information, such as points earned on quizzes and tests and time on task, helps educators intersect with their students in meaningful ways.
For example, the trending column reveals whether students' grades are improving or declining, helping educators to identify students who might need help to stay on track. Flexible, on-demand grade synchronization capabilities allow educators to control exactly which Revel grades should be transferred to the Blackboard Gradebook.
