There are enormous varieties of living organisms on earth classification is the arrangement of organisms into groups and subgroups on the basis of their similarities and dissimilarities biologists have devised techniques for identification, naming and grouping of various organisms.
Creation versus evolution we compare the theory of evolution with the bible's creation account in easy-to-understand terms , using evidence from the fields of paleontology, geology, biology, and astronomy. 1 darwin presented a theory of evolution in 1859 that has been accepted but also debated over the years 2 from the 18th century to today, many scientists—botanist, zoologists, geologists, geneticists—have contributed to the study of evolution. Diversity definition is - the condition of having or being composed of differing elements : variety especially : the inclusion of different types of people (such as people of different races or cultures) in a group or organization. The mechanisms of evolution explained in one video the theory of evolution explains how the enormous variety of life could come into existence.
Teaching and learning about the diversity, ecology and evolution of the microbial world discover the connections between microbial life, the history of the earth and our dependence on micro-organisms. An amoeba proteus, left, with a paramecium bursariaamoeba can change shape and move around by extending their pseudopodia, or 'false feet' paramecium move by using the cilia, or tiny hair-like. Biological evolution explains both the unity and the diversity of species and provides a unifying principle for the history and diversity of life on earth biological evolution is supported by extensive scientific evidence ranging from the fossil record to genetic relationships among species.
Many scientists claim that all living things - plants, animals, and man - began by process of evolution over billions of years this view is defended by many atheists, agnostics, humanists, and skeptics. The detailed evidence is in museums all over the world the published evidence (just for the past few years) is enormous i've listed some of the recent papers from a few scientific journals -- the tip of the iceberg.

Here the idea of evolution is clearer than in plato, especially for the physical world, which is wholly dominated by purpose the transition from lifeless to living matter is a gradual one, so that the dividing-line between them is scarcely perceptible.
In this article, we'll examine the evidence for evolution on both macro and micro scales first, we'll look at several types of evidence (including physical and molecular features, geographical information, and fossils) that provide evidence for, and can allow us to reconstruct, macroevolutionary events. Reuther bild3 ta: marcus bobar assignment 3 6 june 2014 assignment 3 among the enormous diversity present within the world's living organisms today, a problem arises: endangerment.

The living things of the world are extremely varied and intricately made, yet the theory of evolution has always been about simplicity: once upon a time, some chemicals assembled, began to make copies of themselves, and little by little changed into all life forms.
Natural selection is the only mechanism known to cause the evolution of adaptations, so many biologists would simply define an adaptation as a char- acteristic that has evolved by natural selection. Together productively and some will sug- and the absence of a strong empirical link between greater diversity and an improved diversity and inclusion. Termite queens have the longest lifespan of any insect in the world, with some queens reportedly living up to 30 to 50 years unlike ants, which undergo a complete metamorphosis, each individual termite goes through an incomplete metamorphosis that proceeds through egg, nymph , and adult stages.
