Evolutionary developmental biology

Greek philosopher, born in 384BC died in 347BC. Through his work, the “Scala naturae” also called “the great chain of being”, Artistotle tried to analyze the relationship between all living things. “Scala naturae” is the earliest work of taxonomy in biology, which categorized species on Earth from the simplest to most complex. He also declared that species could not ever change over time. Nicholas Steno (1638-1686): Steno was a Danish scientist. Steno was an anatomist and bishop in the Catholic…

Saving the Malabar Hornbill Introduction: As man continues to extend his developmental practices, nature bears the brunt of it silently. Every year thousands of organisms are wiped from the face of earth permanently. The numbers on the almost extinct list goes on increasing too. To blame man alone for it would be the answer to all the problems, but to try to understand how his activities are harming them seems like a more viable option. The Western Ghats of India is teeming with both flora and…

is a process of growth, enhancement and expanding from small to large and less to more. Societal development in the writer’s opinion it is the developmental transformation of social life, social groups, institutions that people need for everyday function enabling those people to flexible living. According to Turner and Hulme (1997:11) a social developmental ingredient measured as well-being in health, education, housing and employment. The writer finds Herbert Spencer’s theory very explanatory…

Using my knowledge from class regarding the criteria for natural selection, I predict the parameter regarding heritability would have the greatest impact on the evolution of beak size in finches because this is the essential requirement necessary for an increase in frequency to occur by natural selection. Evolution is a result of natural selection, so without it evolution cannot occur compared to the other parameters. Also, a population cannot evolve if the trait is not able to be passed down…

“Darwin himself, in his day, was unable to fight free of the theoretical errors of which he was guilty. It was the classics of Marxism that revealed those errors and pointed them out.”-Trofim Lysenko. Lynsenko believed that Marxism, which has transformed into what we call Communism, was able to prove the scientific theory cannot be applied to society due to errors found with Darwin’s theory. When applying Darwin’s theory to society is as if the poor had not evolved yet to withstand challenges…

Arizona State Standards and District Standards: SC02S4 C2 PO 1. Describe the life cycles of various insects/ Butterfly/ Bumble Bee • SCO2S1 C1 PO 2.

in which species of organisms in the 9 major phylum classes of the kingdom Animalia adapted unique muscle systems and how they use them. A phylum class includes organisms that are different but share important characteristics that resulted from evolutionary relationships among major groups of animals that allowed organisms to adapt in terms of the way they locomote. The Phylum Porifera is made up of sea sponges which are stationary plant like organisms found in the sea and coral reefs, sponges…

When finding out unknown bacteria you have to go through several steps to figure out what it could be. I was given unknown bacteria number 28 and asked to run different testing to identify exactly what this bacterium is. I ran 6 test to determine my unknown. These test includes: Gram Stain, SIM, Sucrose, Citrate, MAC, and EMB. Each one of these test are different and they will give a positive or negative feedback which is how we will know which bacterium I have. A gram stain is one of the most…

Rachel Carson, a biologist, was the founder of the modern environmentalism movement during the 1960’s and 70’s. This movement spread quickly throughout the United States. Carson is known today for publishing her very famous book Silent Spring. This book was published during such an important time in history and is significant to this day because it tells us a lot about the environment we live in today. Many people have been fascinated by her book and several other pieces of work. She has…

Being products of evolution, nearly all living things are, in essence, products of their environment. The environment influences which traits are successful and get passed on. Before long, those organisms are directly products of their environment. This phenomenon chiefly occurs when the environment holds all the power over the organism. When it comes to humans, however, we are social animals, we influence and are influenced by those around us. Because of this, humans are not solely products of…
