What is natural selection? [1]

You will be able to access your list from any article in Discover.. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success
Natural selection is one of the ways to account for the millions of species that have lived on Earth.. Charles Darwin (1809-1882) and Alfred Russel Wallace (1823-1913) are jointly credited with coming up with the theory of evolution by natural selection, having co-published on it in 1858
In Darwin and Wallace’s time, most believed that organisms were too complex to have natural origins and must have been designed by a transcendent God. Natural selection, however, states that even the most complex organisms occur by totally natural processes.

Are humans still evolving? [2]

Nowadays, with the availability of better healthcare, food, heating and hygiene the number of ‘hazards’ we experience in our lives has dramatically reduced. In scientific terms, these hazards are referred to as selection pressures
It is selection pressure that drives natural selection (‘survival of the fittest’) and it is how we evolved into the species we are today.. The question is, now we have fewer selection pressures and more help in the form of medicine and science, will evolution stop altogether for humans? Has it stopped already?
To investigate which genes are undergoing natural selection, researchers looked into the data produced by the International HapMap Project and the 1000 Genomes Project.. The International HapMap and 1000 Genomes Projects both aimed to catalogue genetic variation in DNA samples taken from individual humans from across the world.

Which of the following are examples of natural selection? [3]

The example of the black and white peppered moths that got affected during the Industrial Revolution in England is a typical example of natural selection. It explains how the environment favoured certain traits over others
Here, the antibiotic acts by eliminating all the susceptible bacteria, leaving behind the antibiotic-resistant ones which can now survive and multiply, eventually resulting in a new population of antibiotic – resistant bacteria.. The finches of the Galapagos Islands exhibit a variety of different beak types
Evolution of wolves to dogs is considered to be an example of artificial selection by man rather than natural selection. It is said that a few gentle wolves were domesticated by man, and these gradually and eventually have evolved into the various breeds of dogs that we see today due to continuous artificial selection by man.

[Solved] Which one of the following is an example of natural selectio [4]

Which one of the following is an example of natural selection?. – Natural selection was given by Charles Darwin, according to it those populations which are a better fit (reproductively fit) in an environment will be selected by nature and will survive more.
– In a collection of moths made in the 1850s, i.e., before industrialisation set in, it was observed that there were more white-winged moths on trees than dark-winged or melanised moths.. – However, in the collection carried out from the same area, but after industrialisation, i.e., in 1920, there were more dark-winged moths in the same area, i.e., the proportion was reversed.
– During post industrialisation period, the tree trunks became dark due to industrial smoke and soots.. – Under this condition the white-winged moth did not survive due to predators, dark-winged or melanised moth survived.

Which of the following is an example of natural selection?A. Two species of cichlid become less and less alike in the lake environments they both shareB. A variety of dogs are bred for their ability t [5]

Which of the following is an example of natural selection?. Two species of cichlid become less and less alike in the lake environments they both share
Peacocks are selected for mating by females due to their bright plumage.. The venom of a certain salamander species becomes more poisonous as predation by snakes increases.
Hint: In order to first arrive at the correct answer one must know the true meaning of natural selection. In simple words, nature selects the best fit of the species in consideration to make it survive and reproduce

Biology Online Dictionary [7]

The process by which heritable traits increase an organism’s chances of survival and reproduction Credit: Jackie Malvin, (CC BY-SA 4.0 ). What is natural selection in biology? Natural selection is defined as a process in nature through which living organisms adapt and change in response to an environmental condition
Different conditions incline a particular organism to acquire an adaptive trait. These traits will then, be passed on to the next generations
According to Urry et al., (2016) natural selection refers to the differential survival and reproduction of individuals. It is a vital mechanism of evolution where there is a change in heritable traits of a population over generations.

Natural Selection [8]

Natural selection is the process through which species adapt to their environments. English naturalist Charles Darwin wrote the definitive book outlining his idea of natural selection, On the Origin of Species

Natural selection [9]

Natural selection is the process by which some organisms in a population survive and reproduce, while others do not, based on their bodies and behaviour. It is one of the processes by which species change from generation to generation, and is a crucial element of the theory of evolution.
The ancestors of modern giraffes were animals similar to deer or antelope, with necks of ordinary length. However, because the trees in their habitat were tall, those giraffes with slightly longer necks had an advantage over their shorter-necked fellows
Over many generations this process produced giraffes as they are today.. This process of natural selection was first described by Charles Darwin in 1859 in On the Origin of Species

You are sure to know that humans developed from apes millions of years ago. But how did we become so different from our distant relatives, the bonobos and chimpanzees? Many changes that persist in species develop by random mutations and stay within the species because they are advantageous at a given point
Although the reasons are not definite, it is most likely that natural selection is behind why humans lost their tails, learnt to walk upright and lost most of their hair. The hypotheses are quite diverse: for example, not having a tail could have aided with walking on the hind legs, which in turn helps with carrying tools, a key to humans’ survival
What seems clear, though, is that there must have been some reason as to why the individuals that lost their tails and their hair, and could walk upright passed on their genes more frequently to such a point that now all humans walk upright and have no tail. Hairiness varies, but most of us are far from having such a thick coat as a chimpanzee!

Natural selection [12]

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations
Variation exists within all populations of organisms. This occurs partly because random mutations arise in the genome of an individual organism, and their offspring can inherit such mutations
The environment of a genome includes the molecular biology in the cell, other cells, other individuals, populations, species, as well as the abiotic environment. Because individuals with certain variants of the trait tend to survive and reproduce more than individuals with other less successful variants, the population evolves

Understanding Natural Selection: Essential Concepts and Common Misconceptions – Evolution: Education and Outreach [13]

Understanding Natural Selection: Essential Concepts and Common Misconceptions. Evolution: Education and Outreach volume 2, pages 156–175 (2009)
Without a working knowledge of natural selection, it is impossible to understand how or why living things have come to exhibit their diversity and complexity. An understanding of natural selection also is becoming increasingly relevant in practical contexts, including medicine, agriculture, and resource management
This paper provides an overview of the basic process of natural selection, discusses the extent and possible causes of misunderstandings of the process, and presents a review of the most common misconceptions that must be corrected before a functional understanding of natural selection and adaptive evolution can be achieved.. “There is probably no more original, more complex, and bolder concept in the history of ideas than Darwin’s mechanistic explanation of adaptation.”
