The evolution of plants has resulted in increasing levels of complexity‚ from the earliest algal mats‚ through bryophytes‚ lycopods‚ ferns to the complex gymnosperms and angiosperms of today. While the groups which appeared earlier continue to thrive‚ especially in the environments in which they evolved‚ each new grade of organisation has eventually become more "successful" than its predecessors by most measures. Probably an algal scum formed on land 1‚200 million years ago. In the Ordovician period

John Frelinger Dr. Travis Organic Evolution 30 April 2012 Evolution of the Immune System Animals are constantly bombarded by an immensely varied array of disease causing pathogens including bacteria‚ fungi‚ viruses and other parasites. The number of microbes living in the human body outnumber the actual human cells by a factor of 10‚ and for every single species of animal and plant on Earth‚ there are viruses that infect them. With the unrelenting threat of disease-causing pathogens all around

Evolution Is Just A Theory One of the main things that would be studied in biology is evolution. Although most people think that evolution is true and us humans have evolved from our formal ancestors. For the past year mankind has been thinking of one thing‚ which was evolution. The definition of mechanism is how evolution occurs over time. Evolution has been shown over the past billion years and humans have studied the creatures that have physically changed their bodies. The definition of evolution

The Best University in Dhaka University life is one of the most important phases for a student. If you are admitted at a good university you end up learning a lot of things and are a lot smarter than the rest. Among all the universities I took admission at North South University for my under graduation degree. It is considered as the best private university in Dhaka. It is a great place to study for basically three reasons. First of all‚ the environment is excellent for studies. It is completely

Patterns of Evolution Humans alter our environment to suit our needs rather than adapt to our environment based on environmental stressors. Due to this fact‚ we are unlikely to be affected by the pressures of natural selection. We will not likely be affected by further evolution. In convergent evolution‚ unrelated species living in the similar environments become more and more alike in appearance as they adapt to the same kind of environment. Dolphins and sharks are examples of convergent

PART 1: Question 1 Describe the differences between divergent evolution‚ convergent evolution and parallel evolution and provide an example for each type of evolution. Divergent evolution occurs when change from a common ancestral species increases as time passes‚ leading to a speciation event; that is‚ the evolution of two new species. Convergent evolution on the other hand differs from divergent evolution because it is the development of similar features separately in unrelated groups of organisms

land. This change is called evolution. Who founded the theory; what is it and why it happens will all be explained in the following paragraphs. Charles Darwin is the man who is most famously associated with the theory of evolution. In 1859 he published a book a called ‘the Origin of Species’ which explained his theories on evolution. Darwin received lots of criticism and his theories caused much debate when he first mentioned it. This is because his theory of evolution did not match up with religious

Unit 3 - Evolution Notes Evolution involves change over time....from a biology standpoint evolution looks at how organisms change over long periods of time over many generations and hundreds of thousands of years. Source of Genetic Change Mutations are the source of genetic change * Neutral mutations - do not seem to benefit or harm the organism * Harmful mutations - negatively affect the life of organisms * Beneficial mutations - positively affect the life of organisms Artificial
