As scientists, mathematicians and other incredibly smart people started looking up at the night sky, they wondered - why is the universe of the shape that it is? What gives solar systems and galaxies their form, why donât they just scatter and fly away? These questions came up as soon as the scientists at NASA started measuring the gravitational impact of all of the objects in our galaxy, and something didnât quite add up: the total amount of mass and...

Dark matter is an incredibly elusive force which is necessary for many modern theories that describe the movement of galaxies and â effectively â all of the major elements of the universe. One of the reasons that dark matter has arisen as a theory is the fact that when we observe certain galaxies, they have much more kinetic energy then the masses in them would suggest, therefore, a separate force must be at play. However, we have not yet been...

Dark Matter accounts for 84% of all the matter in the universe. The remaining 16% is ânormalâ (also called baryonic) matter, comprised of every single planet, star and galaxy in the visible universe. Dark Matter earned its name because it does not interact at all with the Electromagnetic Force. This means it does not absorb, emit or reflect visible light, gamma rays, ultra-violet rays⌠etc. Since telescopes rely on some form of electromagnetic radiation to function (see graphic below), they...

Dinosaurs first appeared in the latter half of the middle Triassic 230-240 million years ago; they were originally bipedal carnivores, and quite small relative to the colossal dinosaurs that proceeded them. These primitive dinosaurs rapidly evolved into the two major clades we know of today; Ornithischia and Saurischia, Saurischia being comprised of both Sauropoda and Therapoda. Saurischia makes up all carnivorous dinosaurs and birds, as well as the long-necked herbivorous sauropods while ornithischia is classified as any non-sauropoda herbivorous dinosaur...

Evolution is the development of life on earth. This process began billions of years ago and is continuing to this day. Evolution tells us how the enormous diversity of life could develop. It refers to any change in the distribution of alleles within a population over time. In the early 19th century Jean-Baptiste Lamarck (1744â1829) was the first to fully form an evolution theory of the transmutation of species. In 1858 Charles Darwin and Alfred Russel Wallace, both naturalists published...

Much debated topic among psychologist are always, whether our personality and behaviour are governed by nature or nurture. Evidence from various psychologistsâ study have very much agreed that both also can influence and shape who we are. But to what extent, or which is more important is still an ongoing debate. The following contents of this essay will describe about two psychology branches: Evolutionary Psychology and Behavioural Genetics, to dwell on their rootâs origin, ideology approach and methodology used of...

Community Psychology is a very important branch of psychology it understand peoples behavior within their communities, societies, organizations, community psychology focuses more on wellness than illness its an important factor to support towards social change through empowerment of weak groups such as women who suffer from brutality, youth and children living in poverty disabled people elderly and jobless immigrants. However the aim of this thesis was to contribute opportunities to enhance quality of life of people, communities and society. Twenty...

Plato to Darwin to DNA highlights the different understandings of our natural world throughout history. Not only is the reader able to get a detailed view of each periods method of research and development of theories, but also is able to compare them with one another. The âscientific processâ as we know today was incredibly different in the past, and explanations of our natural phenomenon were determined by direct observations and deep philosophical thought. The reader is also able to...

Introduction (200 words) Natural selection, a key concept in evolutionary biology, profoundly shapes the diversity of life. This principle, first elucidated by Charles Darwin, explains how species evolve and adapt through generations. It is the process by which traits that enhance survival and reproduction become more prevalent within a population, leading to the gradual evolution of species. This dynamic reflects the ongoing adaptation of life to various environmental challenges, a testament to the resilience and ingenuity inherent in nature. The...

Abstract Mycoviruses are significant widespread viruses found to be infecting all major groups of plant pathogenic fungi. Mycoviruses require living cells to replicate like other animal and plant viruses. These viruses are transmitted through cell division or during spore formation. Most of the mycoviruses have double strand RNA genome, and few are known to have positive single strand RNA genome, DNA genomes are rear among mycoviruses with one exception of Sclerotinia sclerotiorum hypovirulence-associated DNA mycovirus 1 having DNA genome. Some...

As we go further within the future, the Earth is getting more and more polluted each passing day. It will eventually come up to the point where it couldnât sustain any more lives, having the possibility of it âbreaking downâ. Our reign is coming to an end, which is the reason why numerous people around the globe have been searching for an alternative; a new habitable planet where they could call home. In result, have found the so â called...

Our current theory of evolution in basic terms is that all living things come from a common ancestor and that natural selection caused the adaptions that created all the different species on our planet. This is a huge claim- that everything on Earth is somehow connected. But, what evidence is there to support it? Fossils are time capsules for biologists. They are extremely solid (almost rock solid, get it?) evidence of evolution. Fossils consist of parts of deceased organisms that...

The theory of evolution by natural selection was first formulated in Darwin's book 'On the Origin of Species' in 1859. This is the process that changes a species over time due to changes in heritable physical or behavioral traits. These changes allow an organism to better adapt to its environment which helps it survive and have more offspring. (than, 2018) Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from...

Abstract The fossil record supplies research with evidence of human origins, offering a crucial insight into the study of palaeoanthropology. This discipline has critically developed our understanding of human origins; however, the fossil record is sporadic and incomplete, often precluding a full assessment to the potential morphological scope of past populations. Over the past couple of decades, advances in molecular genetics have precipitated a new age for evolutionary studies in human origins. Research on DNA variation in diverse human populations...

Humans have developed in many capacities that have led to our advantages and technology today. We have developed from over 3 million years ago with brain and body developments. There are six key essential concepts that have helped our species grow, including fire, language, cooking, shelter, clothing, and art. Each of these concepts is connected to each other in a way and can connect these inventions together. They are the basic ideas that we developed that are the first step...

An aspect of biology that interests me is the evolution of humans over many hundreds of years. Human evolution began six million years ago in Africa. This has been proven countless times by evidence such as fossils of human remains which can be dated back to many million years ago. Our first ever relative was a fish that existed 400-350 MYA. It was called the Notharctus Tenebrosus and its first fossil was discovered in 187in 1870. It is linked with...
