The modern concept of genetics was unknown during Darwin's lifetime, and for many years after. Darwin based his theory of evolution upon observation of the similarities and differences between closely related species, and how they could have developed.
sexual reproduction and mutations provide variation among species
how has Charles Darwin influenced people about modern views of evolution
The term 'modern theory of evolution' most likely refers to the 'modern synthesis', which combines Darwin's classical model with modern genetics.
True, they should share fewer homologous structures than two more closely related organisms.
religious beliefs and social structures are closely related
Not at all. Giraffes are mammals, which are not closely related to dinosaurs. Dinosaurs are more closely related to birds and modern reptiles.
A evolutionary form of a bird. It had wings and feathers but still probably acted like a dinosaur but im not sure.
No modern bird is more closely related to dinosaurs than any other.
yes
Woolly mammoths look very much like modern elephants. They are more closely related to Asian elephants than to African elephants.

Whales are related to the even-toed hoofed mammals. Whales are most closely related to modern hippos, and should share a common ancestor with them.
Mammoths are most closely related to modern elephants
Humankind is the perfect example.We have shown with fossils that there are numerous transitional forms, from apelike predecessors, to simple hominins to hominids, to more recent ancestors to the modern homo sapiens.We have shown via genetic, physiological and anatomic comparisons that humans are closely related to certain apes, then somewhat less closely related to other primates, then less closely again to certain groups of mammals, and then less closely again to the rets of mammals.
sexual reproduction and mutations provide variation among species
No. Mammals evolved from synapsid reptiles, a group not closely related to dinosaurs. Dinosaurs are more closely related to modern reptiles and birds than they are to mammals.
