    As a scientific concept, evolution was revolutionary when it was first introduced. With the help of all three of our hosts and the Smithsonian National Museum of Natural History’s new Deep Time Hall, we’ll try to explain how evolution actually works and how we came to understand it.

    This episode was written by Darcy Shapiro.

    If you don't believe in evolution you don't understand it.If you understand evolution it's easy to believe in it.

    Darwin was not only well travelled and well read, he was well fed he apparently ate many if not all of the animals he discovered.

    No such thing as evolution: DNA proves we didn't evolve:1)  Each DNA contains 100 million pages worth of instructions to build the entire body.  Do instructions write themselves?  Nope.  Instructions don't write themselves.  Behind every instruction is an 'instructor' who authored it.  Carl Sagan said:  "The information content of a simple cell has been established as around one trillion bits, comparable to about 100 million pages of the Encyclopaedia Britannica."2)  Every genome is written as a quaternary molecular digital code:  "All present life is based on digitally-encoded information."  (American Academy of Sciences)3)  Each cell contains hi-tech miniature organs (organelles - nucleus, golgi bodies, mitochondria, chloroplasts, etc.) - none of which are naturally found elsewhere - hence no natural explanation for their existence.

    Christians should watch this stuff. At this point I think people who have access to the internet are just like ignoring facts. This is better than going to church. Make this explode pls.

    “The extreme rarity of transitional forms in the fossil record persists as the trade secret of paleontology. The evolutionary trees that adorn our text- books have data only at the tips and nodes of their branches; the rest is inference, however reasonable, not the evidence of fossils.""-Stephen Gould

    Great video I like to find out more the problem that I have a disability I'm a stroke and cardiac arrest survivor just to clarify and the one stupid question I have is if living things change over time including us humans, how come the change doesn't go from having one thing and the next generation its something else?

    If evolution are true, Is there a discovery of specie today that being evolb to new specie?

    A very brief version of evolution.11:11 > "TIME IS A KEY COMPONENT OF EVOLUTION"Other variables are much more important than TIME.If the breeding cycle is very short, then TIME is less required.Many "tricks" can be used to shorten the breeding cycle. Correct selection of species. Acting genetically, environmentaly, etc - simultaneously & sequentially. Increasing "randomness" via radiation, chemicals, etc.In my forthcoming book: "Non-human Cognitive Science", I show how cache systems (software) can use hardware to create "evolution". This evolution video does not show that evolution is software. Hardware (biochemistry here) comes in many forms, but it does not create evolution.

    Something can’t come from nothing. Matter cannot make itself. There is no examples of change of kind. The birds adapted but they always remained birds. There is no fossil examples of the transitions actually happening. A bird is a bird is a bird. It’s not evolution, it’s adaptation. Of course life is always changing, the earth changes. If you are telling me that all life arose from the sea, how did gills magically become lungs? How long did that take? There are fish today that have four flippers, they did not evolve into legs. What really gets me is the absolute certainty of these ideas and claiming to be strictly scientific when no evidence of the beginning or change if kind can actually be provided. DNA is the book of like that was designed. It is not just by accident.

    Becoming quite addicted to this channel and having a decent understanding of both science and english while being a native french speaker I'm starting to seriously consider adding french subtitles on these videos. Though I've never done anything like that I'm sure I could figure it out.

    I literally just had to like the video immediately after they included Wallace. Thank you! However, Darwins theory was actually based on the Mockingbirds. Only later did the finches play a role.
