Dr Losos Experiment Essay
1. In Dr. Losos’s experiment, why was it important that the experimental islands lacked lizards?

It was important that the experimental islands lacked lizards because it allowed each ecomorph to be isolated to make it easier to study their evolutions. It would also allow the species to adapt to the habitat without any competition from other lizards in its way.

2. Dr. Losos’s data suggest that after only a few generations, the lizards on the experimental islands have shorter legs on average than the lizards on the larger island. Explain how the data you collected either supports or does not support this claim.

The data I collected supported Dr. Losos's claim because it shows that because the environment on the island was more suited for

If a species can not survive because its legs are too short, then the species with longer legs will survive and multiply. I believe that the average leg length of the population will shrink because of the environment/ecological niches of the experimental island. The advantage of longer legs is not benefit to their environment therefore the ones with shorter legs will survive better and will produce offspring with short legs. Therefore, the anoles with shorter legs will dominate the population in a process called natural selection. Natural selection was founded by Charles Darwin which is when organisms are better adapted to their environment will produce more offspring and survive. This is the main process of evolution that the the fittest organisms will survive. Anoles lizards developed these adaptations which are specific traits that are developed to improve function for lizards living in certain niches that allowed them to be beneficial in different environments. It is thought that the lizards spread out to several other islands, or if the lizards first inhabited different islands and then adapted to the environment. The environment of the small islands, which consists of small bushes and grass, differ from the environment of Iron Cay, which has varied vegetation. The experimental island favors shorter legged lizards therefore the lizards

    The thorny devil of Australia and the desert horned lizard of North America are examples of convergent evolution. They are distantly related, but have developed some very similar characteristics which help them to survive and thrive in similar environments. The desert environment presents many challenges to survival: windblown sand which is hard to move on, extremely high surface temperatures, and open areas with little shade, food, or protection from predators.…

    The age and anatomy of Pappochelys has made it clear to Schoch and other researchers that it is a transitional creature, one that bridges the evolutionary gap between its lizard ancestors and its turtle descendants. These creatures are an important contribution to science in the study of evolution according to Schoch. They can reveal how specific features, such as the turtle's carapace, evolved over millions of years.…

    By analyzing the microsatellite alleles and comparing the observed heterozygosity in two populations of Blanding’s Turtles, an understanding about how and why genetic variation occurs within different populations of the same species may be obtained. Genetic variation is the basis for evolutionary change, and refers to the differences among individuals in the composition of their genes; examining the genetic variation that may be present in different populations of Blanding’s Turtles may provide meaningful insights into biology, such as being able to understand and predict both the patterns and processes of evolution and fitness in distinct populations.…

    The only native species mentioned are the bioluminescent dinoflagellates and some of the various birds. All other mentioned species are introduced, solidifying the idea that the island was previously inhabited. Though the island is presented as a surreal and unrealistic place, all of its natural phenomena can be explained. Though the lack of some species is illogical, it is even stranger that the only native organisms are animals. All identified plants are non-native, and even the unidentifiable ones are likely to be non-native.…

    Tropical Lizards

    Both articles also predicted that there is just minor impact of climate change on several species of tropical lizards, but currently animal accommodation has been turned into an effective way to survive with these altering periods. Article 1 attacks some recent studies that pointed out the disappearance of many species because of climate change, whereas article 2 strongly believes that the extreme conditions can help many tropical animals modify positively, they will be accustomed to new conditions and unlike the previous reports predicted that they can be died under dissimilar weathers (Wiley 2012). As was noted in article 2, physiology will be varied gradually over many years or many generations, but the animals can be altered and evolved speedily under hot environments (Wiley 2012). Likewise, some researches of Dartmouth College in article 1 believe that most of the lizards from four groups still maintain the faculty of moving under wider conditions during 4 years testing (Logan 2013). Furthermore, many scientists in article 1 have given an evident study to support that open habitats of lizard trials do not influence the forest areas or threaten forest animals because it can be valuable for wildlife animals to encounter a particular condition better (Logan 2013). Besides that, article 2 has discovered that there is a clear connection between lower threat of extinct rates and high genetic difference due to challenging…

    In proceeding toward this unpleasant conclusion I have not guessed or speculated or conjectured, but have used what is commonly called the scientific method. That is to say, I have subjected every postulate that presented itself to the crucial test of actual experiment, and have adopted it or rejected it according to the result. Thus I verified and established each step of my course in its turn before advancing to the next. These experiments were made in the London Zoological Gardens, and covered many months of painstaking and fatiguing work.…

    Venomous Lizard

    Lizards belong to the class Reptilian, Scientists have said that reptiles have been on earth for about 200 hundred million years. Lizards are the largest group of reptiles with more than 4300 species around the world. Lizards are found in sub-tropical and tropical regions of the world. Lizards come in different shapes and sizes. Most of the lizards are quite small have four legs and have a fragile tail that can regenerate when part of it is gone. They look similar to salamanders. Lizards are ectoderms meaning they cold blooded, meaning they depend on outside sources like the sun, to raise and maintain their body temperatures. Eating habits for lizards is very different, it depends on the species. Some lizards feed on iguanas which are insects, some eat rodents, and some eat both rodents and insects. Lizards use their teeth to scare predators off as protection. Very few lizards happen to be poisonous and use their venom as a defence. Other species of lizards rely on camouflage such as the chameleon that is able to change its colour according to its surroundings, as a defensive strategy. Females of most lizard species lay eggs and then are usually left to hatch on their own. The most well-known venomous lizards are the Gila monster and he Mexican Beaded Lizard. They are found in Mexico and south west of United States. These lizards are classified in the Family Helodermatidae which has one genus containing only these two species. Both of these lizards have been known as the only venomous lizards for a long time. But more recently discoveries have been made that there are more…

It was on the Galapagos that Darwin stumbled upon many diverse life forms. (Finch, n.d.)…

    This theory consists of two parts. One is the rate new species migrate to an island and the second part is the speed at which the species disappears from the island. The greatest determining factor for the rate at which a species migrates to the island is how far away it is from the mainland. The biggest determining factor for the loss of species from the island is dependent on the size of the island because smaller islands tend to have smaller populations that can vanish at a much faster rate than large populations. The overall number of species on the island remains pretty balanced when the number of new species arriving matches the number of species vanishing from the island. This theory can help to predict variations in other ecosystems such as ponds, lakes, and even patches of vegetation depending on how isolated they are from other similar ecosystems and the size of the…
