Evo Devo and the Modern Synthesis
Evo-devo is a developing field on the study of evolution in the developmental stages in different species. Though it is a new discipline, it has the potential to contribute a great deal to our knowledge of evolution. This paper will discuss what evolutionary development is and that it should be added to the modern synthesis because studying embryonic stages can lead to a better understanding of human evolutionary history and the future biological path of the species. To determine what evo-devo will lead to, it must be defined. Evolutionary development biology is the study of how environmental changes or mechanical alterations in the stages of an embryo can direct evolution (Hall, 2012). However, according

Recent years have given rise to more fields within evo-devo including, eco-evo-devo, evo-devo-niche construction, and behave-evo-devo (Hall, 2012). All of these sub-disciplines bring to light how looking into environmental factors can change the niche priorities of an embryo. Not only this but studying modern factors can lead to discerning the types of environments that might have lead to humanity’s massive role in the ecosystem. Coupled with Ken Weiss’ argument of behavior-driven evolution, we can assume that environmental mechanics can change the role an organism plays (Hall, 2012). Conversely, understanding these past developments, evolutionists can begin to understand how future environments will contribute to epigenetics and possible adaptations. One extreme example would be the effect other planetary conditions might have on the development of an embryo. All in all, adding evo-devo to the modern synthesis will allow for more of the populous to learn about these …show more content…
As Willmore (2012) discusses, evolutionary development is relatively recent in academic circles. However, the concept of the field has been discussed since Darwin’s discoveries. Stephen J. Gould published a book in 1977 discussing how the connection between evolution and development had been sought since 450 BC (Hall, 2012). Similarly, Hall (2012) writes about the true history of evo-devo and the progress the field made through the 19th and 20th centuries. The real problem with evo-devo seeming young is because it is not added in the Modern Synthesis of evolutionary theory. Hall (2012) argues the current interpretation is very narrow-minded and unlike the ideas Darwin was aiming for. Now, modern schools do not look into the importance of evo-devo and the insights the discipline can bring to our biological history. The current synthesis only describes a change in species on a macro scale through genes but does not count for the development of organismal forms (Hall, 2012). In order to extend the synthesis, evo-devo must be made accessible to non-academic populations (Willmore, 2012). Giving a basic understanding of embryonic developmental factors within evolution to the general population would allow evo-devo to progress as a
In Dinesh D’Souza’s “Staying Human”, D’Souza contemplates the technological advances of the biotech revolution. He considers the effects of this revolution, through its benefits and hindrances upon society. D’Souza also contemplates the role parents will play in this society. Because of advances in biotechnology, parents assume the role of creator and attempt to design children according to their will. When utilizing biotechnology, parents determine the values they believe constitutes a “model Child” and attempt to assume the role of creator.
Do you know how you got here? I’m not talking about how your parents met. I’m not talking about your past. I’m talking about evolution and how we all got here. In the passages I have just viewed “A Fish Out of Water” by Greg Pardo & “Dinomummy” by Ryan Overbee, I have learned that some information that we thought was true was been proven wrong.
For instance, bears have evolved from scary animals that humans feared, to cuddly “teddy bears”. Some may ask how or why this is the case and there are certainly piles of evidence to support this statement. To begin, the bear itself was turned into a “teddy bear” named after Teddy Roosevelt because he could not shoot a bear. In this book, a man named Kelsey Eliasson was “turned off by the way he saw activists like Polar Bears International “Disney-fying” the bear”.
Overall, Darwin knew that species were transforming and evolving over
Natural selection is seen in the finches that Darwin studied on the Galapagos Islands. Environment and food supply changes caused the finches beaks to adapt in a unique way. Studies on Darwin’s finches show us that natural selection in a natural environment is interpretable, observable, and repeatable (Grant, 2003). Natural selection is representable in different types of birds such as the Island Scrub-jay. A study published in 2015 on these Island Scrub-Jays (Aphelocoma insularis) demonstrates examples of natural selection.
Thus, it proves itself as legitimate by conforming to its own process and establishes its clear, lasting impact on the fields it touched. In fact, Fuller’s organization of his presentation of evolution lends credence to the theory itself for this reason, making the layout of his book incredibly effective in substantiating its central claim. Additionally, his framework offers him some leeway in creating a narrative worth consumption; by using this outline, he is able to write a story rather than just compile a list of bland facts as many less effective historical writings often
Organisms can evolve to enhance their ability to catch prey, or flee predators. Coevolution occurs in a predator-prey relationship when the prey evolves in response to pressures exerted by its predator. The predator then evolves in response to the changes in the prey (or vice versa). Inheritable adaptive traits evolve through natural selection, the process by which organisms that have developed favorable traits are capable of surviving and reproducing at greater rates, thus passing their adaptive traits to their offspring. Birds and caterpillars have a predator-prey
Since now we know lots about artificial selection, let 's hear a bit about natural selection also known better as, the process whereby organisms better adapted to their environment tend to survive and
It is undeniable that the foundation of Wilhelm Wundt’s Institute of Experimental Psychology and the introduction of Darwin’s new theory of evolution as descried in Origin of Species has had a huge impact on the development of the modern discipline of Psychology and on society today. In this essay I will examine Wilhelm Wundt’s Institute of Experimental Psychology and Darwin’s theory of evolution from Origin of Species. I will look at what they included and the effect they had on Psychology and society at the time they were published and their influence years after. Firstly I will assess the impact of the new theory of evolution as described in Darwin’s Origin of Species.
From reading the book, the reader is able to learn about “extract proteins’’ , ‘embryos’’, ‘’genetic development’’ and ‘’DNA’’. “DNA evolves over time, like everything else in an organism-hands or feet or any other physical attribute.” “we can take an unknown piece of DNA and determine where it fits in the evolutionary sequence." Crichton was able to communicate these ideas in an entertaining manner, incorporating them seamlessly into his story.. The book’s emphasis on didacticism is important as it helps the reader discover new ideas and concepts, while provoking thought and engaging the reader throughout the
Evolution is the development and change within heritable traits of different populations over generations. Over the years, humans have begun to invent things and change around their environment (the world) to suit their needs. With this is mind, we humans have not been paying attention to how these changes are affecting our evolution as a species. We are cheating natural selection with the design of medicines and medical procedures that allow us to live longer.
Natural Selection is the long gradual process in which Biological traits either become more or less common in a population as a function of the effect of inherited traits on the differential reproductive success of organisms interacting with their environment. In Darwin’s work The Origin of Species he also mentioned evidence for the Theory of Evolution from his voyage around the world on The H.M.S. Beagle. The Origin of Species is probably the most influential work on evolutionary biology. The Origin of Species will help prove my thesis because it introduces the ideas that we base on evolutionary biology today.
This process is known as natural selection, which explains how Charles Darwin’s theory of evolution can occur. Natural selection is an important component of evolution. It occurs when some members of a population are better fit for survival and proliferation than others in that population. The environment in which organisms live plays a large part in natural selection as well.
Nature can loosely be defined as genetic inheritance and genetic makeup which a person inherits from their parents at the time of conception and carries throughout life. What makes nurture important is that it can change the genetic makeup and genetic inheritance that people inherited from their parents. In a recent study in the University of Manchester, Reinmar Hager and Jason Wolf at the Faculty of life Sciences together with their collaborator James Cheverud at St Louis have shown how maternal environment can affect how genes are expressed, influencing the body weight and growth of young mice, even if they are not related to their mother. They have thus revealed that environment may affect how genes are expressed. Focusing on genomic imprinting, the researchers had shown that the environment has had a strong effect on how imprinting influences body weight and growth in mice (Hawoth).
