This poster provides an excellent introduction to animal development, primarily invertebrates. This poster uses a tree branching system that incorporated “nodes.” They are the point at which the tree branches. Each node is a physical characteristic. All of the animals that share that characteristic constitute a clade.
The new cladistics classification system is used to present an overview of the primary clades. The only animals with two cell layers are the sponges. They make up the Parazoa clade, which is the same as the Poriferan phyla. The next step in animal development is the the development of a third cell layer (the trioblastic layer.) which provides the basis for anther clade. All other animals have a hollow ball embryo. They constitute the Eumetazoa Clade. The branching continues through to the last clade, which is accompanied by a brief description of the physical characteristics of its members. This last clade corresponds to the phyla and the phyla name is cited instead of the clade name. This is because taxonomy, comparative anatomy and many other life science classes still use the traditional classification system.
Customers have been universally impressed with the quality, beauty and detail of these posters. Pictures do not do them justice! This is a new type of poster that we call content intensive posters. Each provides a comprehensive overview of the subject presented through images and fact-filled text. They are designed to appeal to people who enjoy reading books, watching informative or educational shows on television and subscribe to such magazines as “National Geographic”, “Smithsonian” and “Scientific American”. They have great educational value and are cherished by teachers, students and professionals.
All posters are printed on high-quality, hard paper that preserves tiny details. Posters are then specially coated with a satin finish that reduces glare and enhances the presentation.
