hind legs and their relatively short‚ thick antennae. The morphology of insects enables the phenomenal success of this class of arthropods. The high rates of speciation‚ short generations‚ and long lineage have caused insects to evolve in many ways‚ resulting in very large variations in morphology. Keywords: morphology‚ Orthopteroid‚ speciation‚ lineage‚ variations INTRODUCTION Morphology is inherent to an understanding of how insects live and function. In contrast to anatomy which is

The Fynbos Biome makes up the largest part of the Cape Floral Kingdom‚ which is the smallest of the world’s six floral kingdoms. The Fynbos Biome in particular is noted for its high levels of biodiversity (the highest in world) and endemism‚ which in turn results in a high number of threatened and endangered species. The Cape Floral Kingdom was declared a World Heritage Site by UNESCO in 2004. 2 Discussion Fynbos is found predominantly in the the South Western Cape in an area extending from just

flowering plants have driven diversification of beetles. The longer beetles reside in these environments with all kinds of flowers‚ the more niches and differences beetles can eventually adapt to. Another theory is that the Coleoptera speciation (Co-Speciation) rates are particularly rapid. The extreme diversity of beetles reflects the Jurassic origin of numerous modern lineages‚ high lineage survival‚ and the diversification into a wide range of niches‚ including the utilization of all parts of

Name: Assignment: SCI203 Phase 2 Lab Report TITLE: Speciation Instructions: You will need to write a 1-page lab report using the scientific method to answer the following question: What would happen if a species within a population were suddenly split into 2 groups by an earthquake that creates a physical barrier like a canyon? When your lab report is complete – submit it in the classroom. Part I: Use the animated time progression of speciation to help you write up your lab report. Part II: Write

consequences. The main mechanism for gene flow between species is a hybrid population‚ either able to reproduce with parental species and thus forming a bridge for gene flow‚ or reproductively isolated from the parental species and undergoing hybrid speciation to form a new species. Research in this area seems to indicate that the crops most at risk of significant transgenic invasion are those with a fixed genetic load‚ thus the best preventative measure would be to increase genetic variability in

perfect form. The process of discovery that drew Darwin into the field of inquiry is described. 3. Infinite Variety Barnacles excited Darwin enough for him to study their intricate variation for seven years even without the expectation to see speciation occurring! The thirteen finches Darwin collected were of a single family and four species; the difficulty in telling them apart is stated in this quote: “’Only God and Peter Grand can recognize Darwin’s finches’” (43). The beginning of the Grant’s

On the Topic of Science and Faith In today’s secular society‚ it is commonly believed that science and faith are completely unrelated entities. However‚ Beginnings by Leonard Brand and David Jarnes argues the opposite.” The main purpose of Beginnings is to display ways in which faith can give some valuable insight in the subject area of science. The book does so by including faith and religion in the dialogue concerning topics that appear to be areas of conflict between science and faith. It efficiently
