We like to pin clarifications or corrections on our videos. We appreciate comments that bring them to our attention. There is a text box in this video that states that natural selection acts on populations, but we want to clarify this. Natural selection is based on differential reproductive success of individuals and this is a mechanism for evolution, which acts on populations, in order for this to happen. Natural selection does *occur* in populations (some references will use the words "*act on*" such as this example esajournals.onlinelibrary.wiley.com/doi/full/10.1890/0012-9623-95.2.24), but as a mechanism, natural selection does so by differential reproductive success of individuals. Our focus is to prevent the misconception that it does *not* produce an evolutionary change within the individual. The individual's survival and reproductive fitness will affect the population. Since we can't easily edit the text box, we are going to opt to remove the portion with the text box as it is explained without the textbox later in the video.

I am a biology major but was losing my interest recently in school and my major. I came here through recommendations last night and watched almost all of your videos since. Each video reminded me why I chose biology in the first place and got me excited again. Your excited voice and sense of humor got my hearts beating with my hopes and dreams once more. I cannot thank you enough. How did I forget how much I loved biology? Thank you, thank you. XOXO

@loricalass4068 7 лет назад

Speciation does not support evolutonism as it is an example of stasis and stasis is the exact opposite of evolution. For ex. over 200,000 species of beetles are all still beetles. There are thousands upon thousands of species of birds, bees, lizards, trees, bacteria, trees, yeast, flowers, whatever. If a new species develops with any of those groups at all, you can bet your bottom science dollar that it will still be just a beetle, bee, bacteria, tree, fish, or whatever. We are supposed to fill in the blanks here with...faith...and think, "Well! If new species develops then things just keep evolving and evolving." But the next step above a species, in the Annimal or Plant Kingdom, is a Family. We aren't seeing any new Families forming. Anywhere. Ever. Accorrding to Darwin's so called Tree of Life and peer reviewed evolutionary literature, new Families have evolved. Over and over and over. However, nature operates today as it did in the past. In the real world, with trillions of life forms, we never see anything developing above the level of a new species. The life forms out there have purportedly had eons and eons of ancestors preceding them which should be showing at least one example of a part this Family "transitioning" to be another Family. But we only see that in the unverifiable, purely theoretical, realm of evolutionary literature, never in any life around us. If there is no evidence for transtiions from one Family to another - and please provide data if you know of any such evidence - then there is no evidence for evolution. But that's just for starters. If you want to take a walk on the wild side and look outside the box, you may find it interesting to see some of my other posts here.

The default dance is truly a masterpiece. Never, in all of history, has such an artistic masterpiece ever been created. The choreography is possibly the most beautiful sight ever beheld by the human eye. The sharp sound of the SLAP when the player’s hands collide perfectly with the beat of the song sends a bone chilling shiver down my spine, every single time I hear it. I find my self watching my in-game avatar performing this phenomenal dance ritual for hours on end. The beat of the song is without a doubt the most amazing musical composition in history, one to rival, if not surpass the complexity and beauty of Mozart’s classics. The default dance has truly revolutionized the future of music, and how artists should aspire to create. Some would describe the default dance as a meme, or just part of the game it is appearing in, however I would strongly disagree. These people simply do not understand that the default dance is the center of existence. The universe, science, and evolution are purely myths, as the default dance was the first life form to roam the Earth. Everything; human beings, nature, everything that defines this planet, has originated from ‘the building blocks of life’, the default dance.

I saw a docu series recently and in one episode they talked about a Tigon (Tiger Lion Hybrid) and how Lions usually have a gene which causes them to grow abnormally large physically ( found in the father's karyotype) but the mothers have a gene that prevents this.But when a Tigon is born its Abnormally large from a lion and a tiger due to the overgrowth gene, which doesn't allow it to live long. I think its the best example of the 2nd Postzygotic barrier you guys mentioned

@usersmml3329 3 года назад

Hi, so a quick question - what exactly is the role of geographical isolation? Like, are there benefits to it when speciation happens because of this type of barrier?

@Dr.IanPlect Год назад

The role it has is causing 2 populations of a species to live apart. This allows for the gene pools of each population to diverge, simply because the 2 gene pools no longer interbreed. Over enough time, this gene pool isolation and mutation within, makes the 2 populations distinct enough for them to be designated different species.
