What question did Darwin ponder that will transform the world? What if the earth was not round? Could the species themselves have changed? How many insects species are on the Galapagos?

Could the species themselves have changed?

After reading the book by Thomas Malthus, On Populations, Darwin realized that both plants and animals produce large amounts of offspring, More are produced than can survive. Those that do survive must compete for resources. a. Who does competition for resources favor? There is not any competition because new species cannot be formed. It favors those that do not have any special advantages. They tend to overpopulate. It favors those individuals that have an advantage. Favorable variations tend to be preserved and unfavorable ones are destroyed. The result is the formation of a new species.

What fascinates Darwin about the differences between land and sea creatures on and near the islands? There were thousands of different species in both land and water and Darwin obtained samples. Land life and wildlife was very sparce (limited, low) but the ocean life had an overwhelming number of species.

After Darwin read the book by Thomas Malthus, On Populations he thought about more indivduals being created than could survive he came up with a theory. What was this theory called? The theory of gravity which Natural Selection which is any trait that gives an organism a slight advantage in survival and reproduction is more likely to be passed down from one generation to the next.

Natural Selection which is any trait that gives an organism a slight advantage in survival and reproduction is more likely to be passed down from one generation to the next.

What did Darwin discover about how coral reef islands appear in the middle of the ocean? The coral reef will ONLY grow in waters more shallow than 200 meters. Darwin discovered that coral reefs cannot survive in deep water. On volcanic islands, the coral grows up and the island sinks down, a fringing reef progresses to a barrier reef, and eventually, leaves a signature atoll.

Summarize Malthus' prediction on human growth. nothing can stop human population growth. Some things like, war, famine, sickness and fighting over resources can slow human population growth. Only war can stop human population growth. Only famine can stop human population growth

Some things like, war, famine, sickness and fighting over resources can slow human population growth.

Darwin returned home to England from the Galapagos Islands. What were his conclusions after consulting with leading scientists about the birds? The birds originated on the same island and have the same beaks. The birds have not changed. All of the birds are of the same species but developed different beaks. The birds have changed. They are different species and must have come from different islands.

The birds have changed. They are different species and must have come from different islands.

Why did Darwin find it fascinating to discover seashells in the rocks near the border of Chile and Argentina, thousands of miles away from water? What does this say about how the landscaped has CHANGED or EVOLVED? Darwin discovered the earth's landscape, especially mountains, remains the same over time and never changes. The mountainous range was invaded by a bacteria causing shells to form. The whole area was thought to once be under water with the earth gradually and continuously changing with land rising in one area and falling in another.

What did Darwin notice about the similarities between the gigantic fossils and animals that he was seeing around him? There were no tree dwellers of any species. There was no relationship among species which Darwin found in South America. There is a powerful relationship between the animals that once lived in South America and those that live there today and entire species can disappear.

What reasoning did Darwin come up with for how plants and wildlife came to inhabit the Galapagos and other islands? dfdf They must have been colonized by different plants and creatures from distant continents.
