What did Darwin wonder about the different finch he observed in his travels?
Darwin wondered if the finches on the Galapagos Islands were an ancester to the mainland finches. It turns out they were, one finch went to the island and its decsandants spead across the island. Geographic isolation caused the gene pools to become isolated and each population adapted to a particular habitat on the Galapagos Islands. Over time all the populations became genotypically different that they do not interbreed. Mating finches look for the beak shape.
What is Island origin hypothesis?
Volcanic eruptions may have caused most islands (definitely some- good examples are the Galapagos islands).
6 What group of organisms is responsible for red tides and ciguatera fish poisoning?
Red tide is caused by an overabundance of specific protists, which infect bodies of water, making the water red. Red tide is extremely harmful to humans, as well as different marine animals.
How can a new species from?
To put it simply, new species can form when organisms within a population become so genetically different they can no longer reproduce with one another without generating harmful mutations. This can be caused by genetic drift and geographic isolation. Two populations of the same species who live in different parts of the world will diverge and go on separate genetic paths, until eventually the two populations become genetically different and branch off into two different species.
What was the first species to be extinct?
The first life on earth was unicellular organisms. These organisms reproduced asexually, meaning that they reproduced by copying themselves. Because they did not interbreed, a slight mutation in the DNA caused a new species to exist. If one of the mutant cells failed to divide, that was a species becoming extinct. Humans cannot even begin to fathom the number of these species there must have been or when they started to become extinct. Extinction is a natural process and cannot be stopped; when we talk about being concerned about extinction we generally mean extinctions caused by modifications made to the environment by humans.

What caused Darwin to develop his concept of evolution based on natural selection?
i dont no It was at the Galapagos Islands where he observed finches andd marine iguanas.
Why is galapagos island endangered?
The Galapagos fur seal is endangered because of food shortages caused by El nino. I'm not quite sure what that is but it has something to do with warm water currents. I suggest using Google to research the topic.
Do humans make impacts on the Galapagos islands?
Pollution caused by the airport there and cars. Deforestation in the creation of crop-fields. Damage to coral reefs by divers and ship anchors. Alien species such as dogs and cats, which alter the food chain.

What is the difference between leprosy and diphtheria?
These two diseases are caused by different infectious organisms and have different symptoms and different modes of transmission. The only real similarity is that they are both serious diseases.
