Ostrich S Long Neck

A tale from the Akamba people of Kenya that explains why the ostrich has such a long neck.

An Engraved Landscape is a contextual analysis of a substantial new corpus of engravings from the Wadi al-Ajal, situated in the Central Saharan region of south west Libya. The wadi is renowned as the heartland of the Garamantian civilization, which emerged from local mobile Pastoral communities in the 1st millennium BC, and dominated trans-Saharan trade and politics for over a thousand years. Extensive archaeological and palaeoenvironmental investigations in recent years have provided detailed insight into the later prehistory and protohistory of the wadi and surrounding areas. However, prior to the fieldwork detailed in this work, only a handful of carvings had been recorded in the wadi. This work is based on systematic survey, conducted between 2004 and 2009, which recorded around 2,500 previously unknown or unpublished engraved and inscribed rock surfaces. All forms of engraving, whether figurative or surface markings, were viewed as significant residues of human interaction with the rock surface and were recorded. The resulting database provides an opportunity to analyze the engravings in relation to their changing physical and cultural contexts, and the discussion offers a fresh interpretation of Saharan rock art based on this substantial new evidence. An Engraved Landscape also captures in detail a unique heritage resource that is currently inaccessible and threatened. This record of the fragile engravings provides an important source of information for researchers and students.

What bird has a large body and a long neck, but cannot fly? It is an emu! Or is it an ostrich? These birds may seem similar, but they are unique in many ways. Lively images, simple text, and a side-by-side comparison feature help young readers learn how emus and ostriches have different appearances and behaviors. Readers will soon identify these flightless birds with ease!

It is only relatively recently that it has been possible to study the neural processes that might underlie working memory, leading to a proliferation of research in this domain. This volume brings together leading researchers from around the world to summarise current knowledge of this field.

The field of educational psychology is primarily concerned with teaching and learning. Educational psychology has also been involved with the topics of motivation, intelligence, memory, cognition, intellectual development and evaluation and assessment. This book presents research from around the globe in all areas of educational psychology.

Birds are among the most extensively studied of all animal groups. Hundreds of academic journals and thousands of scientists are devoted to bird research, while amateur enthusiasts (called birdwatchers or, more commonly, birders) probably number in the millions. Birds are categorised as a biological class, Aves. The earliest known species of this class is Archaeopteryx lithographica, from the Late Jurassic period. According to the most recent consensus, Aves and a sister group, the order Crocodilia, together form a group of unnamed rank, the Archosauria. Phylogenetically, Aves is usually defined as all descendants of the most recent common ancestor of modern birds (or of a specific modern bird species like Passer domesticus), and Archaeopteryx. Modern phylogenies place birds in the dinosaur clade Theropoda. Modern birds are divided into two superorders, the Paleognathae (mostly flightless birds like ostriches), and the wildly diverse Neognathae, containing all other birds.
