Most modern animal and fish?

Postby Norppa » Mon Sep 18, 2006 12:19 pm

Hello,

Which is the newest family of species of any vertebreae animal on earth today? Whic is the newest species inside that family? Newest meaning, appeared most recently.

Which is the newest species and family of fish on earth today? Also, which is the most advanced? Is it possible to declare any fish as more advanced to another?

Thank You in advance people :-) Going fishing now :-)

The way I see it, every species of life that there is now is just as "modern" as any other one in existance, theyre are the best possible expression of specialization for whatever habitat they inhabit.

"Advanced" is one of those words that make a lot of evolutionary biologists cringe (especially non-American biologists) as it carries connotations of the old 'ladder of progress' misconception. "Most recently evolved" and "most advanced" don't necessarily go together (I know you didn't say that they did).

a thing is that both fishes and reptiles developed new structures to adapt them in their environment for the past millions of years so in a assuption that both of them just follow the flow and their environment..therefore they are capable of evolving to other forms of living organisms..a theory relates both fishes and reptiles. we cant assume anything about how modern the animals are because there are possibilities of evolving from their ancient relatives...

Mahargynot:
Why is it "especially non-American biologists" that cringe at the word "advanced"? Is this to infer that Americans do not cringe at the word? What do you suppose they do when they hear the word "advanced"? Ignore the term? Do a little jig? Stand on their heads and spout meaningless mantras? Clap their hands and exclaim with glea, 'Yea, and we are the most advanced!"? Look sullen and sad and recognize that only the more "advanced" cockroaches will survive the inevitable demise that humanity shall practice upon itself and the Earth?

Just curious, :).
