Ancestral species are common on a certain hawaiian island. However, on the islands surrounding it derived species are more common. Does this phenomenon support dispersal or vicariance? Explain.
I think it supports dispersal, because it’s likely that the ancestral species originated on the first island and then through migration moved to the other islands, occupying slightly different niches and conditions and thus becoming different. I don’t think it would support vicariance because if an event broke up all the islands wouldn’t the species be completely different and not derived?

That would be hard to determine since the Google update affected all websites that practised keyword spamming and other over-optimisation methods.
My guess would be the popular niches with a lot of competition, like the making money online and computer/electronics niches.

okay so i need to explain how you would figure this out. A table cloth has a circumference of 100 inches… can it cover a table whose diameter is 30 niches

a. convergent evolution
b. competition
c. mutation
d. co- evolution
e. natural selection
i have searched and searched for this answer and still nothing please help.((:

(A) closely related species in different niches
(B) closely related species in similar niches
(C) unrelated species in different communities
(D) unrelated species in the same community occupying different niches
(E) ecological equivalents in different niches

Other countries are just as mean?? I feel like America is mean in its own ways though.. In stupid ways.. lol Being competitive and cut throating in jobs. Always out to make a buck. Screwing people over with car deals. It is all about greed and corruption in America.
I feel like in other countries though they have their own crazy stuff. They might not have corporations, but they have terrorist they are training and people killing each other and crazy rituals.
So in the end, the entire world has its own ways of being mean and promoting injustice.. It’s all just a matter of how your country handles things. For us BIG BUSINESS is the way. For others TERRORISM is the way. We all have our corrupt niches. Right?
