Group selection

Cryptic Female Choice (CFC) in arthropods. This book is built around research from a variety of experts in the field who together build a book structured around key behavioural, ecological and evolutionary questions in regards to specific taxonomic groups of arthropods, such as, spiders, harvestmen, flies, moths, crickets, earwigs, beetles, eusocial insects along with shrimp and crabs. Being published this year (2015) has lead to the most up to date research in the field, with major…

Darwin’s finches (also known as Galápagos finches) are a group/species of birds from the Galápagos (13 species) and Cocos (1 species) Islands in the Pacific Ocean. Charles Darwin collected these birds on the second voyage on the Beagle in 1831. It is often stated that the finches were the key to the development of his theory of evolution and Natural Selection. They are used as evidence in many of Darwin’s textbooks. The finches Darwin collected included three species of seed-eating ground…

Natural selection can be seen as a force, and evolution as a result. Natural selection can be broken down into three concepts that require it to operate. The first is the constant struggle a species face for survival, which results in the continuation of the successful branches of the species, as the others become extinct. The second requirement is a varying population, these more successful branches only stem from mutated groups or individuals whose features become beneficial when faced with…

The promoter of Social Darwinism was a 19th century philosopher by the name of Herbert Spencer. Social Darwinism is a spin off of the theory of natural selection which was created by Charles Darwin. Social Darwinism covers all aspects of life, including economics, political, and social issues. While Charles Darwin intended natural selection to be about survival of the fittest of things in nature, Herbert Spencer used Social Darwinism to also include survival of the fittest of people in…

biological evolution, natural selection and descent with modification. Over many generations and an extended period of time the genetic change of an organism is bound to happen, these changes are called biological evolution. Scientists have studied these changes and how they occur for many years, all starting with Charles Darwin on the Galapagos Islands.…

The natural simulation done in class was a good representation natural selection in the wilderness. The four things that Darwin identified that must be present in order for natural selection to occur are genetic variation, overproduction of offspring, struggle for existence, and differential survival and reproduction. This activity demonstrated all these factors except genetic variation. For over production of offspring, the beans’ populations were multiplied by three after every round. This is…

cooperation manifested through sociobiological function. It intends to communicate the consequences of self- interest and collaborative behavior; likewise, how does the cooperative trait benefit an individual socially and independently and whether natural selection reveals a correlation from a biological perspective. In addition, how is cooperation affected with an educational social structure? In order to provide an initiative understanding of the development of cooperation one of the key…

Natural selection is the main scientific method of evolution and the precursor to an organisms transformation over a scale of time. In natural selection organisms that survive have heritable traits that aid in reproduction thus becoming prevalent in that organisms population. Jurmain(2013) explains in our textbook, that, through the aid of Thomas Malthus ideas, Charles Darwin was able to grasp the explanation of selection in nature (page40). Jurmain(2013) states “In the struggle for existence,…

to affect the allele, gene variant, frequency. Natural selection is one of these mechanisms. The process of natural selection comes down to variation, differential reproduction, and heredity. In other words, natural selection occurs when there is a variation in traits and one of those traits makes it more likely for individuals with that trait to survive and reproduce, allowing them to pass down that trait to a new generation. Natural selection could be an explanation as to how the frequency of…

We define speciation as the process by which a group of genetically and reproductively distinct organisms emerges from a ‘parent’ population. It is possible for humans to witness the effects of evolution on a small scale. Species display a variation of characteristics - humans, for example, have brown…
