Once upon a time‚ God created a simulation video game based on evolution. It was a video game that gave the player (in this case God himself) many different ways on how to change the environment‚ along with other factors too. There were a type of species from the game’s selection of other species called Barbellus- which had an antennae and a fish tail. God decided to create a large number of these creatures that lived in the ocean of the video game. However‚ in this species’ early stages‚ both populations

studies focused on natural selection by predation being a strong contributing factor of polymorphic color distribution in a population. While there is some truth in this model‚ it may overlook the importance that sexual selection plays‚ as will be depicted in the following examples. Many examples demonstrate that animals in a particular species tend to mate with individuals that share similar color patterns‚ in fact it is rare to see individuals with dissimilar color patterns mate.

to study biology in college‚ the process of natural selection explains so much about the modern day life on earth. There is perhaps no phenomenon more wondrous or perplexing than the development of complex life on our planet. Over the countless years of human existence‚ many have attempted to explain just how life came to be. I too have asked how complex life on earth arose‚ and for this answer‚ I turned to science. The process of natural selection is very important to my worldview because it

Natural and sexual selection One of the first and central mechanisms proposed by Darwin during his life was that of "natural selection." Some may refer to this as "survival of the fittest‚" whereby species that produce offspring have been successful in doing so because they have produced random individual features which have lead them to live longer and pro-create offspring with the same inheritable desired features. Not all individuals will be able to reproduce‚ therefore only the fittest will "multiply

The relative importance of genetic drift and natural selection on flower colour in the annual desert plant Linanthus parryae‚ whose dominant blue and recessive white phenotypes are controlled mostly by one gene‚ is debated. Epling and Dobzhansky found that spatial distribution of blue- and white-flowering plants was consistent with genetic drift‚ and Wright found that spatial distribution was consistent with that expected in isolation by distance‚ both supporting the predominant importance of genetic

caused by radiation or toxic chemicals. The second is Natural selection. Natural selection is the biological characteristics that enhance survival‚ they will increase in frequency from generation to generation. Fitness has a lot to do with Natural selection. Fitness is the ability for an offspring to survive and of course reproduce ‚ therefore giving it’s genotypes to the next generation. There are four basic principles within Natural selection. There is variation‚ heritable‚ populations may have

over the world‚ have developed into unique survivalist. Natural selection has allowed many species to use their survival instincts against their predators. Likewise‚ many species have showed great skill of survival. Let’s use humans‚ for example; we are part of the endotherm family; naturally we generate heat within our bodies‚ and we eliminate heat‚ when we sweat. This skill helps us to run longer distances‚ when our prey can’t. Natural selection works for all sorts of species. Even the behavior of

Natural Selection Lab! Interactive Online Game Simulation! Matthew Beja! September 22! ! ! ! ! ! ! ! Purpose: This experiment was conducted to further understanding about Natural selection. ! ! Hypothesis: I think the green bugs that blend into the grass will eventually surpass the blue ones. Since the blue bugs stand out more‚ they are easier to see. ! ! Procedure: A online simulation was conducted. This simulation started with a screen full of blue bugs. The object of

When I think of evolution‚ I tend to think in terms of a series of what I call happy accidents. A creature through a series of genetic mutations is born with an attribute which fits well with its habitat thus providing it with an advantage over others of its kind. This advantage in turn makes the creature hardier than its compatriots leading to increased chances for survival and‚ perhaps‚ better selection of mates. This uniquely equipped animal then breeds and its new trait is passed on to some

What is the difference between artificial selection and natural selection? (Give an example for both.) The key word in these processes is selection; when we have several clearly different options to decide upon‚ we look at the option we believe serves according to our best interest and “cull” the others. Artificial selection is the process of humans selecting certain phenotypes in organisms to serve their purpose. An example of artificial selection can be observed in the phenotypic diversity of
