Oh. SO some plants take on a specific color or odor taht attracts bees or flies because the primitive plants (thier ancestors) that had some sort of feature like this survived? (which no one tells us how they acquired this feature in the first place) This argument is just as blind for a theist, than the creation idea is to ..whatever it is you are
If we wrere merely talking about an animal migrating by following a flock of birds, then yes you win.
1- But how does a beaver know how to build a perfect **** comparable to human damns in effectiveness and form?
2- How do the bees know that the best way to construct their honeycomnbs is a HEXAGON? (the shape that uses the least material and covers the most volume)
3- Why is it that mankind looks to nature to improve tecnology? Kevlar was invented after studying spider webs. STeel gerters that hold suspension bridges were designed with the human muscle tendons in mind.
Starts answering, stop nit picking the details.
AND, if you're so relying on instinct being explained. Check out Darwin's chapter on INSTINCT, it sthe chapter right after "PROBLEMS ON THEORY". He doesn't like instincts cuz it cannot be learned or transmitted.
Animals dont acquire NEW KNOWLEDGE of how to build things, no matter how long you give them.
ANYWAY! Im off on vacation for 2 weeks. SOrry ill miss your response.
1- see my post above and my explanation of spiders below
2- see above
3- Because nature has had millions of years and countless challanges to overcome compared to our few thousand years of engineering. If you compare early animals to their evolved descendents there is often an improvement in their physical structure that is adapted to the enviroment, horses for example. The same can happen with behaviors since they're both genetic.
Beavers and bees are both social animals so their behaviors can be both genetic and learned. To eliminate that variable and see purely genetic instincts at work we should look towards a solitary animal such as the spider.
Spiders are solitary animals that may never come into contact with adults of their species except for mating so the only tools they have are their natural abilities and instincts. The web design of a spider is species specific, if you look at the webs of two different spiders who never met, live in the same area, are the same species their webs will be practically identical. The web design is determined upon the enviroment and prey it is designed to catch. If introduced to a new enviroment the spiders web must be capable of catching enough prey or it will die. Natural selection takes over from there and only the successful design genes are passed down. Spiders of the same species but in different locations with different prey may have different web designs because of genetic drifts favoring a certain design from the previous area. The same conclusion can be used with other animals on how they create their "perfect" designs although with social animals you must also consider the possibility of part of it being spread around. Even in semi social animals such as mice we are able to manipulate their building habits thru genetic manipulation.
So we have two options here. 1- The behavior is gentic, which we have evidence for. 2- A god is talking to the spiders, which we have no evidence for. Hmmm... tough call.
"AND, if you're so relying on instinct being explained. Check out Darwin's chapter on INSTINCT, it sthe chapter right after "PROBLEMS ON THEORY". He doesn't like instincts cuz it cannot be learned or transmitted."
Get with the times, yet again your over a hundred years behind the times. Darwin knew nothing of genetics when he wrote the book, he had no knowledge of genetic based behavior either. That's why there is "Neo-Darwinism". It's the same basic theory but it corrects the mistakes Darwin made due to his limited data at the time.
"Animals dont acquire NEW KNOWLEDGE of how to build things, no matter how long you give them."
Depends exactly what you mean by knowledge. Chimps are capable of using reasoning to complete simple tasks such as stacking crates to reach a bannana suspended from the ceiling. Didn't a gorrilla, Koko, even learn sign language? No gorrilla before has ever done such a thing and it was accomplished in mere years. We're not the only animals capable of reasoning and thinking things out before we act, we're just the best at it.
As for knowledge such as instincts you're wrong again. New behaviors can also be learned thru social interaction. I doubt you read the easy link on animal behaviors so I'll copy/paste an exerpt about variations in feeding habits of a species that is based upon where they were born. These are solitary animals that wouldn't have picked up their behaviors from others.
"1. Steven Arnold tests the garter snake (Thamnophis elegans) for food preference. (Fig. 22.2)
2. Inland populations are more aquatic and feed on frogs and fish; they refused to feed on slugs.
3. Coastal populations are more terrestrial and feed on slugs.
4. Hybrid newborn garter snakes had an intermediate acceptance of slugs.
5. Work with smell receptors and tongue flicks showed physiological differences underlie the behavior."

Yet again you're wrong and only see the evidence you want to see. Your quote on Darwin is correct however you neglected that evolution has come a very long way since Darwin, genetics being a major factor that he had no knowledge of. And yet again your only arguement for intelligent design is that "I dunno how it happens, God must have dunnit".
