The video “Dogs and More Dogs” presents one of the most perplexing questions in evolutionary biology: how did the diversity of dogs evolve from a relatively homogeneous population of wolves. Anthropological data suggests that dogs came into existence some fifteen thousand years ago. In terms of the history of earth and the majority of the organisms that inhibit it, dogs are still very young. It is thus very remarkable that one species (wolves), which must have looked somewhat alike, could have given
One dominant aspect is the existence of dogs within these cultures. Dogs are common throughout the world, either as a domestic pet, a protector on a farm, or an assistant for hunting; amongst others. Regardless of the reason for having a dog most people have either owned one for themselves or has known somebody who has owned one at some point in their life. Despite the relative normality of having a dog in your life in one way or another, the reasons for dogs coming into existence is not common knowledge
In order for a species to survive, its population has to evolve. Evolution is the process of gradual change driven by natural selection to improve survival. Evolution is the explanation of how life got to its current state. Before the idea of evolution, the Bible gave the explanation of how things came to be, the Theory of Creation. Charles Darwin is credited for developing the theory of evolution. Scientist such as Georges Cuiver, James Hutton and Charles Lyell, and Jean-Baptiste Lamarck heavily
frequent over time. Species don’t try to adapt to their environment. Adaptation to the environment is inevitable if a species has the right kind of genetic variation. (pg. 117) The thought that “everything happens by chance” is essentially wrong. Evolution by selection is a combination of randomness and lawfulness. First a “random” process is the occurrence of mutations that generate an array of genetic variants, both good and bad; and then a “lawful” process (natural selection) that creates these
purpose of this essay is not to prove “Darwinian” evolution, as the writer would be performing a feat already done by others, but to examine a certain track of thought amongst Creation proponents. Specifically their noting certain improbabilities of evolution's ability to “design.” I'll evade defining the individual concepts because they've all been described before, and far better than I could manage, although I'll point out that micro/macro evolution distinction is largely Creationist lingo, as is
Has the domestication of dogs influenced a shuffle in their genetic make-up? RESEARCH QUESTION; Has the domestication of dogs influenced a shuffle in their genetic make-up? WHAT IS A GENE; the definition of a gene is “a distinct sequence of nucleotides forming part of a chromosome, the order of which determines the order of monomers in a polypeptide or nucleic acid molecule which a cell (or virus) may synthesize” (Oxford online dictionary, 2014). This can be understood to be a component
Evolution can be found among almost every type of creature, if not all living creatures. Indeed, there are many articles and research being done about evolution in sea organisms. Seeing as evolution is based on abilities to obtain food and shelter, the end results usually ended up with an animal or organism evolving to better obtain either of these. For example, the head of a dwarf seahorse was found to have evolved to better catch their prey, the copepod (Ornes, 2013). The shape of the head
Weaknesses of the Theory of Evolution According to the theory of evolution, approximately 3.8 billion years ago some chemicals accidentally structured themselves into a self-replicating molecule. This beginning spark of life was the ancestor of every living thing we see today. Through the processes of mutation and natural selection, that simplest life form, has been shaped into every living species. A British naturalist and geologist by the name of Charles Darwin was the first to formulate a scientific
Throughout the history of evolution there have been many different methods and ideologies that have affected the gene pools and phenotypes of species, one of those being "Artificial Selection". Artificial Selection is when humans breed animals of the same species together to create a specific overall trait. (Wikipedia, Learner.org, 2010) A great example of artificial selection is the history of dog breeding. Throughout history humans have bred dogs to further develop more ideal physical and behavioral
More and more scientists are daring to step away from evolution, as a basic argument for how life came to be and develop on the planet. It just does not hold water to explain how life started and develops. The conclusion favouring these scientists is intelligent design but at the moment this has not got the well thought out theories which evolution has. It is still in its early stages of understanding and requires far more research into what it means before it can be defined scientifically, it only
