Podcasts about artificial selection

We often think of evolution as ‘something that happened' in the past. But of course, evolution is a constant, powerful process and one that is often unleashed by human behaviours.Often this is deliberate, we'll look at how artificial selection has shaped our crops, livestock and domestic pets, and we'll find out how modern science is uncovering the genetic changes that lie beneath. But sometimes human behaviours unleash powerful and altogether less welcome evolutionary forces…join us as we uncover them together!This lecture was recorded by Robin May on 20th March 2024 at Barnard's Inn Hall, LondonThe transcript and downloadable versions of the lecture are available from the Gresham College website:https://www.gresham.ac.uk/watch-now/human-led-evolutionGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

Have you ever wondered how there are so many breeds of dogs in the world. Or, have you wondered why there are so many varieties of fruits and vegetables. It's all thanks to artificial selection and selective breeding!

On this ID the Future, Taking Leave of Darwin author Neil Thomas and host Jonathan Witt continue their conversation about Thomas's journey from Darwinian materialism to theistic humanism and a thorough skepticism of Darwinian theory. Here Thomas links the heroic posturing of modern atheists Richard Dawkins and Bertrand Russell, on the one hand, and on the other, the heroic fatalism of poetry stretching back to the early Middle Ages and, further still, to the ancient Greeks. Thomas also draws a link between the animistic thinking of much ancient pagan thought and the magical powers attributed to the Darwinian mechanism. Thomas explains why he now views the latter as essentially “crypto-animism.” In their wide-ranging conversation, Thomas and Witt also touch on Read More › Source

We don’t know why dogs became man’s best friend, but we have some ideas.  And those ideas take us back anywhere from 10,000 to 40,000 years ago.They are perhaps the perfect visual example when it comes to witnessing the power of the gene pool and how a selection process, whether natural or artificial, can affect it.  For show notes and more, please visit https://EvolutionTalk.com Written, Produced, & Narrated by: Rick Coste

My AP Biology Thoughts Episode #4 Welcome to My AP Biology Thoughts podcast, my name is Sid and I am your host for episode #4 called Unit 7 Evolution: Artificial Selection. Today we will be discussing what artificial selection is, examples of it and how it connects to evolution. Segment 1: Introduction to Artificial SelectionArtificial selection is when humans use genetic variation in a population of species in order to select which traits they want passed down. Artificial selection occurs when human intervention in a species causes significant change in a gene pool. Segment 2: Examples of Artificial SelectionDogs are one of the best examples of artificial selection. Today, when you're walking down your street you may notice many different kinds of dogs. Some are large, some are small, some have brown fur, some have black fur. But why do all of these dogs look and behave so differently? This is because of artificial selection. Despite their many differences, all dogs are the same species. And as I said before, different dogs will look different, act different and have different sets of advantages and disadvantages. Humans have been using this for thousands of years in order to get these loyal companions for many different purposes. Thousands of years ago, dogs' ancestors were just wolves. After humans tamed and bred them for thousands of years, they have become what we see today. However, humans didn't just breed them randomly. They were selective in what traits they considered advantageous and made sure those were the traits that were to be passed down. For example, rottweilers were bred specifically to herd cattle. In order to breed a dog to do such a task, humans purposely breed two dogs with characteristics that would allow them to be efficient herding dogs. By doing this, humans select which traits they want passed down to the next generation of dogs for their own advantage. More examples of this are terriers that are good for catching rodents. In the early stages of what we see as dogs today, the wolves that have become dogs were probably those that were genetically capable of being more comfortable around humans. These wolves likely were able to eat remaining food that humans had left over allowing them to survive and reproduce which caused more wolves that were comfortable around humans. So initially, this was natural selection. After a while humans may have found use for these wolves. Some were able to get rid of pests, some were able to herd, some offered protection. They allowed those wolves to reproduce and after many years we now have dogs as we see them. Today, since a wolf and a dog would be unable to mate, we know that they are now different species entirely.  Examples of artificial selection in different species occur as well. On farms, chickens, cattle, sheep, and pigs are the result of artificial selection and selective breeding. For cows, farmers would selectively breed cows to have cows that serve their purpose the best. They may choose cows that are best suited for meat to reproduce and create more cows that can be turned into meat for human consumption. Farmers also might breed cows that are best suited for milk production together to create more generations of cows that are best for milk production. This is done for a variety of farm animals for a variety of purposes. Still, farmers don't use artificial selection on just animals. Artificial selection is used to create cabbage, broccoli, cauliflower, brussel sprouts, and kale. Surprisingly all of these vegetables are of the same species. Similarly, bananas are not found as we know them in the wild. In the wild, bananas are small and oval shaped and full of seeds. After humans selected the bananas which were longer and sweeter, they were able to create the sweet and easy to eat bananas we see today. This is another example of artificial selection.  Segment 3: Content ConnectionsAs we know, in the population of every species...

In this episode, we discuss about the impact of humans and domestication on biodiversity and evolution.

This we week finally get back to talking about Artificial Selection and get through the last eight songs on the album. We also talk about industrial music, sports movies, From First to Last, and an up and coming new project. Enjoy the episode and stay safe out there!

Tyler, Brennan and Kyle take some time to argue with one another about each song from Dance Gavin Dance's 2018 record: Artificial Selection.

We get into the first five songs of Artificial Selection, talk basketball briefly, discuss music videos, give Anthony Fantano some shit, and then go over our favorite parts of the Dance Gavin Dance AMA. Stay tuned to the end of the podcast for a VERY SPECIAL PROGRAMMING ANNOUNCEMENT!

We Talk About Artificial Selection

*CRINGE WARNING!*

this is about artificial selection!

This is for science

This is a podcast all about the artificial selection in birds. Enjoy!

The Week 26 recap covers SCP-4251 "Natural Selection" (7:17), SCP-4846 "Friendly Fossils" (23:35), SCP-4851 "Artificial Selection" (35:42), SCP-4692 "The Curious Case of Jackson W. Parnell" (47:21), SCP-4497 "Whose Cuisine Reigns Supreme?!" (1:07:00), and the weekly mailbag (1:27:40).

Darwinian evolution claims to have the explanatory power and the evidence to fully explain life's apparent design. Dr. Ray Bohlin explores the evidence.

Part of the fun in recording a podcast is trying to get everything done in one take without making mistakes. Sometimes that just happens, where I start to say a name of a band and then sound like I have marbles in my mouth. Other times there will be "technical difficulties" like having a cat decide that she needs to be up on the desk at the same time. But we never let these issues stand between you and the amazing Creative Commons Metal Music that awaits your ears. We have music from Hedphelym, EntröpiaH, Six is the God's Number, COMMUNION, Gmork, Recuerda Que Puedes Morir, Insidious Process, and Skankshot. Now if you'll excuse me there's a cat that is not letting me get these show notes typed up. I mean, it's only been an hour since she was last fed, and yet she's recording vocal parts for an amazing metal album. Roaaaawr indeed.

Will Swan (Dance Gavin Dance). A conversation with Will ahead of a the release of the new album, Artificial Selection. 

Dance Gavin Dance are one of those bands that refuses to be pigeon-holed. Their sound is as eclectic and diverse as you could get within genres and as such is a delight to listen to. At times it feels as though two separate CD's are overlapping at the same time, creating a whole new musical dynamic that owes as much to experimentation as it does to courage from the band."We have the backbone," stressed Will Swan, guitarist, in reference to how they can genre hop so effortlessly and effectively. "Even when we are jumping around and changing genres you can still tell it is DGD because of the vocal style and the style of everyone n the band. We bring that to whatever we're doing regardless of the genre and it ends up being that cohesive DGD sound whether we do it intentionally or not."One of the more unique aspects of the bands sound is the contrasting vocal styles of the two frontmen. While it is not uncommon to have dual vocals, the range between the two on show here has to be heard to be appreciated, with Swan admitting this was a key factor in putting the band together."Yeah, I like having those dual vocals," he nodded, "and that idea when we started was kind of unique. After a while other bands have done it and it has become a normal thing but it was a little bit weird at the time we came out having a straight up clean vocalist and a screamer. It was different and I liked that. It allowed for some chaos and also a lot of melodic moments so you could hear that duality."Listen to the attached audio to hear Will speak about the bands upcoming album, Artificial Selection, on June 8, as well as the behind the scenes workings of putting that album together and the difficulties the band faced in picking singles to promote the album. Will also discusses the unconventional song titles and film clips, the climate that helped create Dance Gavin Dance and more.Kris Peters

Background: Since the times of domestication, cattle have been continually shaped by the influence of humans. Relatively recent history, including breed formation and the still enduring enormous improvement of economically important traits, is expected to have left distinctive footprints of selection within the genome. The purpose of this study was to map genome-wide selection signatures in ten cattle breeds and thus improve the understanding of the genome response to strong artificial selection and support the identification of the underlying genetic variants of favoured phenotypes. We analysed 47,651 single nucleotide polymorphisms (SNP) using Cross Population Extended Haplotype Homozygosity (XP-EHH). Results: We set the significance thresholds using the maximum XP-EHH values of two essentially artificially unselected breeds and found up to 229 selection signatures per breed. Through a confirmation process we verified selection for three distinct phenotypes typical for one breed (polledness in Galloway, double muscling in Blanc-Bleu Belge and red coat colour in Red Holstein cattle). Moreover, we detected six genes strongly associated with known QTL for beef or dairy traits (TG, ABCG2, DGAT1, GH1, GHR and the Casein Cluster) within selection signatures of at least one breed. A literature search for genes lying in outstanding signatures revealed further promising candidate genes. However, in concordance with previous genome-wide studies, we also detected a substantial number of signatures without any yet known gene content. Conclusions: These results show the power of XP-EHH analyses in cattle to discover promising candidate genes and raise the hope of identifying phenotypically important variants in the near future. The finding of plausible functional candidates in some short signatures supports this hope. For instance, MAP2K6 is the only annotated gene of two signatures detected in Galloway and Gelbvieh cattle and is already known to be associated with carcass weight, back fat thickness and marbling score in Korean beef cattle. Based on the confirmation process and literature search we deduce that XP-EHH is able to uncover numerous artificial selection targets in subpopulations of domesticated animals.

In the 18th and 19th century evolutionary biologists, including Darwin, emphasised the similarities between natural evolution and artificial ‘ improvement’ of livestock under domestication. They believed that studying domesticated animals and plants could illuminate the mechanisms of natural evolution.
