Question 1 1.1) Hemichordates share some characters with echinoderms and chordates. Pharyngeal slits they share with chordates. Hemichordates are the sister taxon to echinoderms as described by Ambulacraria hypothesis, then gill slits are an ancestral feature for deuterostomes. These gill slits are supposedly lost in in lineage but some researchers have found evidence for gill slits in extinct carpoid echinoderms. The Ambulacraria hypothesis unites echinoderms and hemichordates on the basis of a…

In 1859 Charles Darwin published his book “The Origin of Species”. This book explained his theories of how animals and humans were formed. The beginning of the earth has been a mystery frustrating the minds of scientist for many years. Darwin’s Theory of Evolution is a change in the genetic material of a population of organisms from one generation to the next. Though changes produced in one generation are normally small, differences with each generation overtime can become substantial changes in…

Tullis, Paul. "When You Walk Into a Zoo, Are You Helping Animals or Hurting Them?" TakePart. N.p., 02 May 2014. Web. 16 May 2017. .

microbe symbiosis and the environment can affect each other. Very few studies have targeted this factor in the past, and I believe it is important to identify with this factor of symbiosis in order to fully understand how the environment and the species within that habitat directly and indirectly affect one…

However, there were different species of birds in Bali, Borneo, and the western islands of the archipelago compared to Lombok, New Guinea, and the eastern islands. On the western islands, there were white cockatoos, different species of honeysuckers and even megapods. On the eastern islands, there were woodpeckers, weavers, starlings and many other birds that were not present on the…

Lizards belong in a large class of animals called Reptilia, which contains over 8225 species. Reptiles are animals that are ectothermic (cold-blooded) vertebrates that breathe air. Most reptiles are oviparous (egg-laying) animals with the exception of some ovoviviparous (live-bearing) constrictor snakes and vipers, as well as a few lizard species. They are also theropods, vertebrate animals that have four limbs or are descended from animals with four limbs. Deciphering the lizard classification…

definition of a species as being a class of individuals sharing common characteristics, with the ability to reproduce with another member of the same species to produce a fertile offspring. However after this essay was assigned, I began researching and found that there are areas where this definition can be difficult to apply. There are four major definitions and concepts that can be applied to a ‘species’. The biological species concept, the morphological species concept, the ecological…

Vocalization is an essential type of communication for passerine species. Bird is a primary example of using auditory signals between intraspecies and interspecies. This research paper will examine the European warblers, mockingbirds and sparrows to show that songs are specifically developed by male birds in order to attract females and they are also the way for females to evaluate potential mates to ensure reproduction success. Vocalization is also a mechanism used by this taxon to be able…

seven wonders of the world. It is a popular tourist destination with over 2 million visitors every year. It earns $5-6 million every year from these visits. It is a home for many animals such as 30 species of whales, dolphins and porpoises. It is also a breeding ground for animals such as six different species of turtles. The great the barrier reef is ancient and to some is dated back to around twenty million years ago. Sadly the great barrier reef is threatened by many things such as climate…
