What did scientists conclude from the studies conducted on North Atlantic killer whales? A B C D The conditions for natural selection were met. The two groups have converged into a second species. The conditions for natural selection were not met. The two groups have diverged into species.

In which of the situations below would speciation be most likely to occur? You can choose more than one answer. a. Seven lemurs escape from an enclosure at Duke University. To everyone's surprise, they establish a small but viable population coexisting successfully with humans in a partly suburban environment very different from their native Madagascan habitat. b. Bighorn sheep occupy mountains from Canada to Death Valley in Southern California, interbreeding all along the way. The populations at the two ends of the range live in very different environments. c. A few individuals of a butterfly species were blown to an island during a severe storm. d. A population of juniper shrubs is split by the formation of a canyon. Every year, strong winds carry a small amount of the shrubs' pollen across the canyon.

n the late 1800s, the saltation hypothesis (hopeful monster hypothesis) was proposed as a way to explain how speciation happens. Why was this hypothesis ultimately rejected by "the new synthesis"?     Because it was silly     Because it required individuals to evolve rather than populations     Because it could not explain where mutations came from     Because we discovered the DNA nature of genes

Can you please help answer this question?

Can you please explain why E is correct?

Cana a change in the physical enviroment of a population result in evolution by natural slection?(hint: remember the peppered moth's camouflage and color changes of tree bark due to pollution)
