Wing evolution 3of4

Wings have evolved four times in the history of life on planet Earth. Insects, Pterosaurs, Dinosaurs and Bats. This series looks at these amazing evolutionary developments and the advantages which these features provide to the organism which has them. Life conquers the air.

Certain organisations continue to parrot the phrase "no transitional fossils have ever been found". However, the list of species which possess transitional features continues to grow. Epidexipteryx hui, Protoavis, Protarchaeopteryx, Archeopteryx, Avimimus, Sinosauropteryx, Caudipteryx, Rahonavis, Shuvuuia, Sinornithosaurus, Beipiasaurus, Microraptor, Nomingia, Epidendrosaurus, Cryptovolans, Scansoriopteryx, Yixianosaurus, Dilong, Pedopenna, Jinfengopteryx, Sinocalliopteryx, Sinornis, Ambiortus, Hesperornis, Ichthyornis

UG! These documentaries are always so badly worded. Anti-evolutionist morons eat this shit for breakfast. "Why did birds *want* to fly." "Wings *suddenly* appeared in the fossil record."

Most of us who aren't idiots know what the narrator means but dumb people seize on such miswordings and use them to bolster their case against evolution.

creation vs evolution.....

evolution wins(big time).

@Siddis33 its safe to say that if they evolved wings then they most likely could not use their arms to climb

@4alexza Individuals do not evolve, populations do.

This is a great video i love learning about the evolution of things, i just want to know now how certain genomes are activated or created to give a certain species their ability fly or other physical advantages to help them survive. if anyone has a link to such research i would love to learn =)

Evolution rulez!!!!

[Siddis33]

I have a problem with this flight developing theory from running uphill. In order for an animal to start flapping their ill adapted forelimbs to aid climbing they'd have to give up any other function of their forelimbs and claws, like climbing with them.

@4alexza imagine a whole group of people that bowl to make a living. In this group there will be natural (genetic) variation. Some people will have slightly longer arms then others. Over many generations the genes for longer arms will be slightly in the advantage because they help the bowler to make a living. Now its only a matter of time before longer arms will come to dominate the population.

[4alexza]

They theory doesn't make sense. If I was a bowler and after YEARS of bowling my bowling arm SOMEHOW became longer than my other one because my body saw a need to "adapt" that. My children would not have long bowling arms and thus what they are suggesting could NOT have happened. It is ludicrous in the highest degree.

This is a really good one. Thanks, djarm67.

It was so interesting to learn about this theory for how flight may have evolved in birds. I've always wondered about the possible intermediate stages.

I wish, though, that the video had gone into at least some detail about how insect wings may have evolved. I suppose it could have started with mutations that allowed certain insects to glide briefly while jumping from one tree to another, or something like that.
