What did Darwin predict causes one species to evolve into another species?

Darwin proposed that evolution could be explained by the differential survival of organisms following their naturally occurring variation—a process he termed “natural selection.” According to this view, the offspring of organisms differ from one another and from their parents in ways that are heritable—that is, they …

What is Darwin’s Theory of species change?

Charles Darwin’s theory of evolution states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve.

How did Darwin become convinced that species could change?

Evolution of Darwin’s Theory Like Lamarck, Darwin assumed that species can change over time. The fossils he found helped convince him of that. From Lyell, Darwin saw that Earth and its life were very old. From Malthus, Darwin knew that populations could grow faster than their resources.

What did Darwin discover about species from one island to the next?

In this island Darwin noticed that most species were similar but different from other in the other islands, giving enough evidence to theorize that species change and this is related to their feeding and surroundings. He collected finches that helped him to understand this resolution.

Which observations did Darwin make?

Darwin’s important observations included the diversity of living things, the remains of ancient organisms, and the characteristics of organisms on the Galápagos Islands.

Which observations led Darwin to establish a relationship between extinct and living animals select all that apply?

Which observations led Darwin to establish a relationship between extinct and living animals? The bony shells of armadillos resembled the shells of ancient Glyptodon fossils. The fossilized remains of giant sloths were found in places where smaller sloths now live.

What observations did Charles Darwin make during his voyage across Galapagos Islands?

One key observation Darwin made occurred while he was studying the specimens from the Galapagos Islands. He noticed the finches on the island were similar to the finches from the mainland, but each showed certain characteristics that helped them to gather food more easily in their specific habitat.

What did Darwin observe about species on islands?

During his visit to the islands, Darwin noted that the unique creatures were similar from island to island, but perfectly adapted to their environments which led him to ponder the origin of the islands’ inhabitants. Among those that struck Darwin so greatly were the finches that are now named in his honor.
