Celebrity Xpedition cruise to Galapagos Islands in 2007
Starting in the late 1800’s tortoises became popular pets, were used as food, and the shells were used to make various products. Sailors started capturing tortoises from the Galapagos Islands and surrounding areas. The population of giant tortoises declined rapidly. This rapid reduction in the population caused a severe reduction in the gene pool and the traits of the remaining tortoises became common. Traits were lost that were present only in the part of the population captured and taken away. Which force of evolution does this scenario represent?

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,

A plant or animal that is indigenous or native to one place but found nowhere else. Like komodo dragons or Galapagos giant tortoises. Or is there no such term, just my imagination?
Goodness gracious you people are good. I looked both those words up in the dictionary and you are both completely correct.

Why do people hunt and take tortoises in the Galapagos??
The Galapagos Islands are a world apart – in almost every way. Frankly, I did not know what to expect when I embarked on this journey. In preparation, I read again Charles Darwin’s “The Origin of Species.” When I finally followed (literally) in his footsteps, I found myself overwhelmed and speechless in the face of such beauty, unspoiled by any form of civilization. This is the closest thing to time travel you can find on earth. Sadly, I’m used to wild animals running away from me, being afraid of all humans as potential predators. But not so here on these islands. In fact, I had to watch my every step, so I would not hurt nesting Albatross or Blue-footed Boobies who showed no inclination to get out of my way for the sake of self-preservation. More than once, I nearly squished an Iguana blending perfectly into the rocky landscape. The best part of the Galapagos wildlife scene, of course, takes places under water. Bring your snorkel gear if you come here, because you are going to tango with the local seals, sea turtles and even the occasional shark (all harmless, I was told). The best (and in my opinion only) way to see the islands is to go by ship. I traveled comfortably to all the islands on the motor yacht “La Pinta.” This recently renovated vessel offers comfortable accommodations, excellent food and good service. There are other yachts in the area, so you have a choice, even in high season. But I do recommend that you make all your travel arrangements at least one …

A. Tortoises with dome-shaped shells were found on all of the islands.
B. The shape of the Galápagos tortoise shells varied with their different habitats.
C. The tortoises resembled fossil remains that were found on the islands.
I am doing an awareness project of some Issues of Ecuador and i decided to do it on the one of kind almost to extinction, Galapagos Tortoises, things i really want to try to give awareness is if they do go into extinction what would happen to the ecosystem, the balance towards other animals and as well as what it could affect Ecuador
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..
