Biology Evolution questions?

Aug 252010

What kinds of differences did Charles Darwin notice about the different species of finches and tortoises on the Galapagos islands, and how did his observations influenced his thinking about natural selection,

What did Darwin find in the Galapagos?

I just took a test today on Evolution and I was wondering how many new species did Darwin find on the Galapagos and what were some of the more important ones? We learned about the Tortoise the Marine Iguana and Finches, what are some more?

Are human beings really the greatest creatures on Earth?

I recently got into an argument on whether or not humans are really so vastly superior to animals. Her argument was that animals can’t talk, they don’t have feelings, and they can’t create tools like human beings can so they are inferior. My argument consisted of pointing out that animals can communicate with each other, and several cases have been made to argue the fact that animals do indeed have feelings. I also used Darwin’s observations on the finches on the Galapagos Islands, stating that animals ability to adapt to overcome certain anatomical adversities evens the playing field. She is a devout Catholic so she told me that Darwin is a crock and God created all.

What I’m asking here is whether or not you believe that animals are truly so inferior to humans on an intellectual scale, or have they merely adapted to a point that fulfills all their base necessities? Are we only the dominant beings because we lack the ability to adapt and overcompensate for that through invention?
I wish to correct myself here. Previously I said that humans lack the ability to adapt through evolution, which is wrong because over thousands, maybe millions, of years man adapted to become what we are today.

Another thing I would like to make clear is that adaptation is all about time and place. People say all the time "if we adapted from monkeys, why are there still monkeys around?" Those monkeys lived in the thick rain forest so they did not need to adapt that much. The creatures we evolved from lived in plains areas, so we had to evolve to become upright to watch for predators. We created tools out of the necessity for them, the first being merely sharpened rocks at best. It would simple be a hassle to have a beak.

The internet, cars, and the computer are used to make our lives easier, but are they really needed. Like I said we overcompensate with our inventing, we make these things not because we need them but because we want things faster. We live our lives without all of it.
Another thing that I’m going to add, even though most people aren’t going to read it. I’m arguing that humans have put ourselves up on a pedestal and that we aren’t as great as we try to make us seem.

Question 1 (Multiple Choice Worth 2 points)

Darwin visited the Galapagos Islands several times. He observed some very unusual species. One species of bird, the finch, interested him. He observed some differences in the finches living on different islands. The finches that lived on each island had a different beak. Some beaks were short some long. Some beaks looked straight while others curved. Darwin believed that each species of finch was related but had developed some special beak adaptations because there were different food sources on each island.

What is the main idea of this paragraph?

Finches on different islands have different beak structures which Darwin believed was related to what they ate.

Finches have different diets

Darwin believed that finches can live anywhere as long as their beak structure is well suited for the food supply.

Finches are picky eaters

——————————————————————————–

Question 2 (Multiple Choice Worth 2 points)

The theory of evolution describes

how species reproduce.

how species become extinct.

how species change over time.

how species migrate from place to place.

——————————————————————————–

Question 3 (Multiple Choice Worth 2 points)

The theory of evolution does not

describe how DNA is formed.

support adaptation.

say that populations change.

support the process of natural selection.

——————————————————————————–

Question 4 (Multiple Choice Worth 2 points)

The theory of _______ tells us that favorable traits will become common in a population over time.

Mutation

Natural Selection

Translation

Evolution

——————————————————————————–

Question 5 (Multiple Choice Worth 2 points)

Fossils can help us

predict the future

prepare for changes in the environment

respond to changes in the environment

learn how species have changed

——————————————————————————–

Question 6 (Multiple Choice Worth 2 points)

Darwin studied specific species of animals on the Galapagos Islands and other places

similar species in different areas with unique traits.

all birds have the same size beaks.

giant turtles live longer than other species because of their large hearts.

fossils hold the key to the past.

——————————————————————————–

Question 7 (Multiple Choice Worth 2 points)

Natural selection does not

make species stronger over time.

select what a species needs.

cause changes in a population.

increase how often favorable traits are passed on.

——————————————————————————–

Question 8 (Multiple Choice Worth 2 points)

The genetic make up of an individual is called the

phenotype.

genotype.

DNA structure.

characteristics.

——————————————————————————–

Question 9 (Multiple Choice Worth 2 points)

According to the scientific theory of evolution

individuals have the same genes.

only dominant traits are passed on from parent to offspring.

populations change over time in response to changes in the environment.

populations never change.

——————————————————————————–

Question 10 (Multiple Choice Worth 2 points)

In order to be accepted, a theory, such as evolution, must be

testable

observable

testable and observable

neither testable nor observable

If Creationism is right then how do animals adapt to constantly changing environments?

Example Darwin’s finches. In isolation genetic drift caused them to develop different characteristics. The exitinction of one of the insects that they preyed on died some would be able to continue to live due to genetic mutations. If God created finches perfect then there would not be any variation and just about any change could mean an extinction.

Did your god decide that he would make finches of different beak sizes to live on each of the galapagos islands?

help me with a problem about Darwin's Theory of Evolution?

The Galapagos Islands support a variety of animal species. Darwin’s finches, in particular, are a diverse and highly specialized group- the beak of each finch species is particularly adapted to eating a certain food. How do you think the tiny Galapagos Islands can support this variety of animal species?

How did animals get redistributed around the world after Noah's flood?

Marsupials to Australia, New World monkeys to South America, Old World monkeys to Africa and Asia, etc.

In particular, why do island habitats such as New Zealand, New Guinea, and the Galapagos have many unique species of some Orders of animals, and none of other Orders. For example, the finches of the Galapagos, which fill the ecological niches held by other types of bird in other places? The evolutionary answer is that a couple of finches made it to the Galapagos and then evolved into many different species of finch, but what’s the Biblical answer?
True, finches can fly, but the same problem applies to the various species of giant Galapagos land tortoise, which can neither fly nor swim.
If it’s simply migration, why aren’t species of animals distributed more uniformly? Why should ALL species of kangaroo go to Australia, leaving none near Mt Ararat or anywhere in Asia?
Paulie D -

I require that religion be consistent with the world as it is, and I am curious about everything in the world. Are you suggesting this question should not be asked?
