Evolution of new species of finch observed

[Enki]

The hybridization of two closely related species can result in viable offspring. Whether one chooses to call these offspring a new species or sub species doesn't really matter, and is best left in the hands of the taxonomists in my opinion. Indeed, if you google 'San Isidro owl' you will come across pictures of this fairly new and viable hybrid, and one which I have been lucky to see when I went to Ecuador. The jury is still out as to whether this is a new species, or not.

However, it will be interesting to see whether we can learn more about another of evolution's methods, that of genetic drift, in what seemed a very restricted and inbred population of this new species(sub species?) of Galapago finch.

Vertebrates are constructed on a basic four-limbed pattern. To have wings, we'd have to do without arms or legs, which would not be much of an improvement. [Edit] Actually, it'd have to be arms we'd have to do without, as they, not legs, are analogous to birds' wings. Legs are in the wrong position.

wings would be great, they would be a huge step forward...

And so....?

As I said in #19, I'm fascinated to know what bizarre misunderstanding of evolution is leading you to ask about this...

Humans do have the capacity to fly. Haven’t you noticed?

I have flown countless times but not under my own power...

That reminds me, my 'angel' wings need servicing.

Saying that wings would be good, seems to imply that evolution has targets or plans.   Err, no.

it would seem some people think that is true, i often wonder how male and female of any species suddenly sprouted together and what advantage that would produce..

Sprouted together?
Suddenly?

Explain please.

Only people who are ignorant of how evolution works.

lmgtfy.

why would a species produce male and female and why would it happen at the same time??

Once again I'm left wondering what your actual misunderstanding is and just how deep your ignorance runs.

Sexual reproduction predates any modern species and is now thought to have been present in the last eukaryotic common ancestor. You also do understand that sexual reproduction can happen before distinct sexes, don't you?

That really suggests a total lack of understanding of evolution I'm afraid. Have you read any of the links provided?

so what would have caused male and female of a species to develop at the same time??

FFS at least read the answers you're getting - maybe even risk a glance at the links?

just answer in your own words, why and how would make and female of a species develop at the same time in the same place?

It's not necessary for that to have happened - as you would know if you'd have been arsed to read #37 (even if you didn't follow the link).

You know Orgel's Second Rule states that "evolution is cleverer than you are." - which is meant to mean, not that evolution is actually clever, but that people who can't see how evolution could have done something are lacking imagination.

It seems that fundie evolution deniers are particularly lacking in imagination - and also the ability to do internet searches, follow links, or even read posted answers.

You haven't the faintest idea what you're talking about, and you make a bigger fool of yourself with every post. Quit while you're behind!

Why don't you go to your local library and see if they've got the Ladybird Book of Biology?

If that's not available then perhaps Janet and John Play Doctors and Nurses?

Come to think of it, they didn't, necessarily. There are insect species which are almost entirely female, and which are usually parthenogenetic (google it), but which occasionally have it off with the very rare males of the species to introduce a bit of genetic variation. They could have managed without males altogether for millennia until evolution came up with males of the species. I've no idea whether that is actually what happened, but given the possibility of parthenogenesis in an all-female population of primitive creatures, males may have made their appearance much later.

that's the oldest and most pathetic brow beating excuse ever used, you must be to dumb to understand it if you do not believe it, what a croc...

I'll add "evaluate and check information found" to the list.

It wasn't an excuse - if it was you wouldn't have an answer. You asked a question that you obviously hadn't thought about, let alone tried to find the answer for yourself and then ignored the relevant information when it was supplied to you.

It doesn't take much knowledge and imagination to realise that male and female didn't have to suddenly appear at the same time.
