Adaptations and Natural Selection

“The video describes how faster rabbits are more likely to survive and reproduce in an environment with foxes. If scientists examined fossil records from that region over many generations, what changes in rabbit leg bone structure would they likely observe, and how would this support the idea of evolution? The video explains that male elephants with larger tusks are more likely to win mates and pass on their genes. If scientists studied fossil records of elephants over time, what would they expect to find regarding the average tusk size in earlier versus later fossils, and how would this relate to natural selection? The video discusses how emperor penguin chicks that can tolerate the cold are more likely to survive and reproduce. If scientists analyzed fossil records of emperor penguins from different time periods, what differences in bone density or feather structure might they find that would indicate adaptation to colder temperatures over generations?”
