What are two observations made by Charles Darwin during his 5-year voyage that led him to conclude that living species evolved from extinct species?

Darwin came to understand that any population consists of individuals that are all slightly different from one another. Those individuals having a variation that gives them an advantage in staying alive long enough to successfully reproduce are the ones that pass on their traits more frequently to the next generation. Subsequently, their traits become more common and the population evolves. Darwin called this "descent with modification."

Another observation he made was the fact that the plants and animals of the Galápagos Islands resembled those of the nearby coast of South America.

∙ 13y agoone was when he saw the changes in the beaks of the sparrows he was studying. he saw that each beak was specifically designed for the bird, how it ate, and what it ate.

What did Charles Darwin discover in the cliffs of Punta Alba?
Fossils that provided insight into the theory of evolution
How the fossil record indicates a long history of changing life forms.?
The fossil record shows that different species have evolved over time. The fossil record also provides evidence of how a specific organism evolved from earlier species. The fossil record shows that organisms have become more complex over time. It also shows which organisms lived during the same time period, which have a common ancestor, and which have become extinct.
How where humans invented?
Humans were not invented; they evolved gradually from some now-extinct group of primates. This ocurred as different inherited traits made some individuals more likely to survive and pass on their genes. This resulted in a gradual change in the population that eventually led to what we now call humans. Assuming we don't go extinct any time soon, wer are not an end product either. Our population may eventually evolve into something a bit different from how wer are now. What that might be, nobody knows.
Carbon-14 is useful for dating fossils that are what?
Old
What does threatened mean in science?
It means that the species is close to being extinct.

How do you determine whether species were extinct or evolved for example prehistoric man isn't considered extinct because it has evolved to modern humans while dinosaurs consider extinct?
dinosaurs arent extinct just like humans they evolved into birds and lizards
How did eoraptor extinct?
eoraptor did not went extinct they have all evolved in the begeining of the jurrasic and later in late jurrasic they have evolved into the birds
how did australopithecus extinct?
they evolved into humans.
What should i conclude as a scientist if a newly founded species has a pelvis but no legs?
A scientist would conclude that the ancestors of the given animal DID have legs, but, that over time, they evolved to become legless. Some examples of this kind of evolution include snakes, whales, dolphins, and the extinct, superficially fish-like icthyosaurs.
Why did the Rhamphorhynchus become extinct?
Like all dinosaurs, we still do not know how this prehistoric animal became extinct. it evolved though, because it lived in the Jurassic period of the mesosoic, and did not become extinct, but it evolved

How did apatosaurus become extinct?
they havent gone extinct they have just evolved into humans
Why did the dinosaurs evolved?
They didn't evolve! They went extinct.
What extinct cephalopod evolved in the Silurian period?
Ammonite
What happened to cro-magnons?
They evolved into homo sapiens and then came extinct.
What is a palaeosubspecies?
A palaeosubspecies is an extinct species of animal which evolved into its present form.
