million, 385 million, and 340 million years old, respectively. The difference of the colors of all of them have to mean they were at least deposited differently. Adding on to this, there are different animals in different layers. “Creatures like trilobites that lived in the more distant past are found in the lowermost layers. Creatures like ancient mammals that lived in the most recent times are found in the topmost layers.” This most likely raises questions for creationists; it does for me at least

Predator - Prey Relationships The relationship between predators and their prey is an intricate and complicated relationship; covering a great area of scientific knowledge. This paper will examine the different relationships between predator and prey; focusing on the symbiotic relations between organisms, the wide range of defense mechanisms that are utilized by various examples of prey, and the influence between predators and prey concerning evolution and population structure. Symbiosis is

The Permo-Triassic mass extinction: what died out LIFE IN THE SEA Fusulinid foraminifera disappeared completely, although other foram groups suffered much lower levels of extinction. Palaeozoic corals (Rugosa and Tabulata) also vanished. Stenolaemate bryozoans and articulate brachiopods suffered near-complete extinction. The extant echinoderm groups all experienced severe bottlenecks at this time: only two lineages of crinoids and echinoids made it into the Mesozoic. Several echinoderm groups (e

NO!! I disagree with the statement that whatever human beings create or destroy is by default natural. Though they are part of the animal kingdom and therefore part of nature but they have no rights to harm nature. In many Religions such as Traditional, Judeo, Christian, and Islam in particular has shown that our relationship with nature is that nature was made for us. Plants, animals, even the planets, all were made for humans. The British naturalist Charles Darwin made a theory of natural selection

Almost all of the major taxonomic groups were affected during this event, but marine communities took the brunt of the extinctions, wiping out one third of all brachiopod and bryozoan families (aquatic invertebrates), and groups of conodonts (eels), trilobites, and graptolites. There are several suspected causes for the mass extinction, with a heavy focus on climate change and glaciation driven cooling, in addition to the minor contribution of the elimination of several habitats from sea-level fall,

The Theory of Evolution: “Grievously Hypothetical” *Rough Draft* First Publicized in Charles Darwin’s On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life, The Theory of Evolution has been a widely excepted theory all around the world. According to the Pew Research Center, approximately 60% of all American adults believe in Darwinian evolution (Public 's Views on Human Evolution). This is an absurdly large amount of the United States’

The Earth has been around for a long time. Humans have been around for a long time. America has been around for a long time. However, these long times are on vastly different timescales, and are not even close to being comparable to each other. To human minds, however, it would seem as though anything beyond the scope of their lifetime blends into a series of events on a page. The years before their birth sticking together into an amalgam of history, distorted beyond recognition. We place prominence

Before we get started, I guess we should actually distinguish, ‘What IS the Burgess Shale?’ Well, it is said to be a “shrouded legend” deep in the Canadian Rockies discovered in the early 1900s by Charles D. Walcott, notorious Smithsonian Secretary (Adler 2013). According to Haug, Caron, and Haug in their research article ‘Demecology in the Cambrian: Synchronized Molting in Arthropods from the Burgess Shale’ the Burgess is “arguably the best-known Konservat-Lagerstätte”. While the Burgess Shale is

The diversity of these structures is usually extremely high (both intra- and interspecifically) and have existed in many animal groups, including extinct trilobites and dinosaurs, to beetles, birds and hoofed mammals (ungulates) found today (O’Biren et al., 2017; McCullough et al., 2016; Emlen, 2008; Emlen et al., 2005; Emlen, 2001).

Macrofossils and ichnofossils can be used to generate reconstructions of ancient environments based on the nature of preservation. Both of these allow us to interpret different aspects of the environment the fossils were preserved in and its controls, however advantages and disadvantages of each must be considered so that the data collected is treated with the appropriate caution. Macrofossils, ranging from bones to shells, with exceptional preservation allowing for the analysis of soft tissues
