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,

Part of an exhibit for the California Academy of Sciences on the Galapagos. Enigmatic yet poorly understood, many species of these ancient tortoises have been lost to exploitation. Sea farers of old captured these animals live, using them as fresh meat on long voyages leading to the decimation and even loss of some species in the achipelago. This old fellow is happy to be protected in the Charles Darwin reserve.
1. Who published his own theory of evolution by natural selection about the same time as Charles Darwin?
2. Any inherited characteristic that increases an organisms chance of survival, like webbed feet, sharp claws, or speed is called an ___.
3. A giraffe that stretches its neck longer by reaching for food and then passes this long-necked trait on to offspring is an example of ____ of ____.
4. Another name for divergent evolution is _____.
5. On the Galapagos Islands, Darwin observed that the characteristics of many animals and plants: a) all looked alike. b) varied from island to island. c) were acquired through use.
6. Because of its similarities to artificial selection, Darwin referred to the "survival of the fittest" as: a) use it or lose it. b) natural selection. c) homologous structures. d) struggle for existence.
7. The idea that each living species has descended with changes from other species over time is called: a) descent with modification. b) struggle for existence. c) artificial selection. d) acquired traits.
8. An inherited characteristic that increases an organism ability to survive and reproduce in its specific environment is called: a) homologous structure. b) vestigial organ. c) adaption. d) speciation.
9. A human appendix, whale hipbones, and a skin’s legs are examples of: a) homologous structures. b) embryonic mates. c) vestigial organs.
Answer any that you know. I REALLY need help, thanks!
FaceFull, I’m loaded with TONS of other AP and preAP homework and I just need to get this out of the way. It’d be nice if you would help, thanks.
Aqua, thank you so much!!

Charles Darwin goes to the Galapagos Islands and notices that Turtles are different from Island to Island. He decided this means that Animals develop by adapting to their habitats, and came up with a hypothesis on evolution. – Is this inductive or deductive thinking?
Well I have to do a report for school and I tried everything and go no answer on this so here are the questions.
All about galapagos plants!
What effects biodiversity of plants?
How did the plants get to the islands?
How many species of plants are represent to the island?
Are any of the plants used for export (to make money)?
How ae the plants adapted to survive their environment?
What is their average size, color, ect.?
What do the terms native species and invasivve species mean?
Which plants are native species?
How long have these plants inhabited the island?
Which plants are invasive species?
What is the concern/problem with invasive species?
What plants did Charles Darwin primarily study when he visited the Galapagos?
What are the three main species of cactus on the island?
How and why are these plants important to the environment?
How do animals interact with these plants?
Do any organisms eat the cactus?
Thanks.

The environments that Charles Darwin studied exhibited little biological diversity.
By careful anatomical study, Darwin found that the many species of plants and animals on the Galapagos Islands were unique and bore no relation to species seen in other parts of the world.
The tortoises of the Galapogos Islands are among the largest on Earth.
After returning to England, Darwin studied his collections for 10 years.
Darwin named the process by which evolution proceeds adrtificial selection.
—All of these questions are true or false..lol..please help if u can..

the Galapagos Islands, a famous group ofislands due to the visit by Charles Darwin aboard the HMS Beagle in the1830s. What about these islands caused Charles Darwin to be convinced life must evolve by natural selection?
a.Many of the animals on the Galapagos Islands were very similar to
animals seen on the South American coast and their only differences
seemed to be those that had to exist to survive on an island.
b.The life span of most animals on the Galapagos Islands are so short,
Darwin could watch changes in each generation.
c.The Galapagos Islands were unique in the fact no humans had ever
visited them and Darwin could see nature at its essence.
d.Charles Darwin noticed the animals must have evolved independently
from all other species on Earth because no similar animals or plants
could be found anywhere else on Earth.
