This golden rule of friendship works every time - guaranteed! The simple communication techniques that follow will help you keep the focus of the conversation on the person you are talking to and make them feel good about themselves. The Big Three Our brains continually scan the environment for friend or foe signals. Eyebrow Flash The eyebrow flash is a quick up and down movement of the eyebrows. Head Tilt The head tilt is a slight tilt of the head to one side or the other. Smile A smile sends the message "I like you." Empathic Statements Empathic statements keep the focus on the other person. Example 1 George : I've been really busy this week. Tom : So you didn't have much free time in the last few days. Once the basic formula for empathic statements has been mastered, more sophisticated empathic statements can be constructed by dropping "So you..." Example 2 Flattery
Homo erectus - H. erectus is a well known hominid IntroductionThroughout the early years of paleoanthropology, there were only two different species that were attributed to the genus Homo. These included the Neanderthals, and Homo erectus. In the early 1960s, this began to change, and human ancestry seemed to be populated by many different players. Accordingly, erectus is one of the better-known members of genus Homo, especially in terms of its well-established place in paleoanthropology. This has begun to change, however, and now some question its place in human evolution. Some (e.g., M. The species was named by Eugène Dubois (it was originally designated as Pithecanthropus erectus) in 1894, after his 1891 find from Trinil, Java, in Indonesia (Trinil 2). The material was later associated with the Chinese material from Zhoukoudian, and renamed Homo erectus. Diagnostic Features This view has some validity in that these species are usually considered “chronospecies” due to anagenesis. Another African erectus specimen is KNM-ER 3883.

Math Books: Recommended books about mathematics Countless math books are published each year, however only a tiny percentage of these titles are destined to become the kind of classics that are loved the world over by students and mathematicians. Within this page, you’ll find an extensive list of math books that have sincerely earned the reputation that precedes them. For many of the most important branches of mathematics, we’ve provided what we consider to be the best math books for the subject at hand. Contemporary Abstract Algebra by Joseph Gallian Review: The seventh edition of Contemporary Abstract Algebra covers the basics of abstract algebra with clarity and a rarely seen brightness. Abstract Algebra by David S. Review: Serious math learners will be thrilled by the rigorous conciseness of this textbook. Introduction to Algorithms, Third Edition by Thomas H. Review: Introduction to Algorithms is a distinctly theoretical but all-around comprehensive book. Art of Computer Programming, The, Volumes 1-3 Boxed Set by Donald E. by Tom M.
Biologija.com.hr - Vijesti - Biologija - Evolucija vidljiva tijekom samo jedne generacije Idući puta kada se nađete u prirodi dobro se osvrnite oko sebe. Ne samo da uživate u aktivnostima izvan kuće već vjerojatno svjedočite i evoluciji koja vam se odvija pred očima. Novo istraživanje objavljeno u časopisu Science početkom ovog mjeseca, a koje se bavi utjecajem kukaca na populacije biljaka, pokazalo je da se evolucija može dogoditi puno brže nego što se prije pretpostavljalo, čak tijekom samo jedne generacije. Znanstvenici sa Sveučilišta u Torontu, zajedno a suradnicima, izveli su eksperiment koristeći dvogodišnju pupoljku (Oenothera biennis), tipičnu samooprašivajuću biljku koja producira genetički identične potomke. Biljke su posadili na dva polja od kojih je svako u početku sadržavalo 60 biljaka sa 18 različitih genotipova (biljke koje sadrže različite setove mutacija). >>> Istraživanja na algama mijenjaju poznatu evoluciju biljaka Rezultati pokazuju da bi evolucija mogla biti važan mehanizam koji uzrokuje promjene u cijelom ekosustavu.

ZipcodeZoo Top 10 Signs Of Evolution In Modern Man Humans Through history, as natural selection played its part in the development of modern man, many of the useful functions and parts of the human body become unnecessary. What is most fascinating is that many of these parts of the body still remain in some form so we can see the progress of evolution. This list covers the ten most significant evolutionary changes that have taken place – leaving signs behind them. Goose Bumps Cutis Anserina Humans get goose bumps when they are cold, frightened, angry, or in awe. Jacobson’s Organ Vomeronasal organ Jacobson’s organ is a fascinating part of animal anatomy and it tells us a lot about our own sexual history. Junk DNA L-gulonolactone oxidase While many of the hangovers from our “devolved” past are visible or physical, this is not true for all. Extra Ear Muscles Auriculares muscles Early humans ate a lot of plants – and they needed to eat them quickly enough that they could eat a sufficient amount in one day to get all of the nutrients they needed.
I - LES NIVEAUX DE LA SELECTION : de la molécule à l’individu - Le Cactus Heuristique L’histoire de la sélection naturelle Charles Darwin (photo à gauche) défini la notion de sélection naturelle comme la « préservation des variations favorables dans la lutte pour la vie, et le rejet des variations préjudiciables ». Le concept de sélection naturelle postule un tri de certains caractères biologiques au cours des générations, qui découle du fait que les porteurs de ces caractères se reproduisent mieux que les membres de la population qui en sont dépourvus. A partir des connaissances acquises sur l’hérédité, la sélection naturelle a ensuite été divisée en 3 modes d’action agissant sur la distribution des phénotypes dans une population: - La sélection directionnelle : elle sélectionne un type unique de phénotype dans la population. Le niveau d’application de la sélection n’a pas vraiment été intégré aux débats qui ont animées les évolutionnistes peu après l’arrivée de la théorie de l’évolution à la fin du XIXème siècle. Pourtant, en 1945, le biologiste suédois G. S.J. Les gènes
Pauls Online Math Notes Replication Evolution - Home Mark Ridley's Evolution has become the premier undergraduate text in the study of evolution. Readable and stimulating, yet well balanced and in-depth, this text tells the story of evolution, from the history of the study to the most recent developments in evolutionary theory. The third edition of this successful textbook features updates and extensive new coverage. The sections on adaptation and diversity have been reorganized for improved clarity and flow, and a completely updated section on the evolution of sex and the inclusion of more plant examples have all helped to shape this new edition. Outstanding features of the third edition of Evolution include: DEDICATED WEBSITE - provides an interactive experience of the book, with illustrations downloadable to PowerPoint, and a full supplemental package complementing the book. TWO TYPES OF BOXES - one featuring practical applications and the other related information, supply added depth without interrupting the flow of the text.
