ladder of evolution

[noz92]

does anybody know where i can find a complete copy of the ladder of evolution? or does anybody know the complete ladder?

[JaKiri]

'Ladder' implies discrete stages, not a constant state of transition, so I'd disagree with such a thing validly existing by today's science.

[noz92]

so how do i know the order things evolved in, how do we know for sure that the jellyfish was the first multicelular animal to evolve? what scale do we have for evolution?

[atinymonkey]

We asked the giant jellyfish. He's rather accommodating when it comes to genealogy. It started with Gregory, the amoeba, who just decided to become a jellyfish.

Isn't evolution fun?

[Sayonara³]

You're looking for charts that show the known history of adaptive radiation.

[noz92]

yes, do you know where i can find any?

[pulkit]

When you are looking for an evolutionary chart, shouldn't you be searching for a particular creature's ?

[noz92]

well, i guess that would work, know where i can some of those, i'd say more like homo sapien sapiens, but i'd like one that goes back to the first single celled organisms.

[pulkit]

If I find ne charts etc. I'll forward them

[LucidDreamer]

I believe what your looking for is called a cladogram.

[noz92]

If I find ne charts etc. I'll forward them
alright, thanks

Uhm, for the moment ignoring the obvious fossil gaps, the charts you desire would be huge(size and lenghtwise).

[noz92]

well, i'm just wanting one that goes pretty far back, thats really what i'm asking for.

[admiral_ju00]

In that case, let me see what kind of graphs I can find(although I'm pressed for time, so nothing will happen 'till late tonight or tomorrow).
In the mean time, I suggest you look up a man named Carl von Linne, and a bit of his work.

You might be able to find what you need here: http://www.palaeos.com/

[admiral_ju00]

Here are some graphs for you. I merely provided you a compilation of graphs, but if you do it careful enough, you should be able to link the various graphs into one.

I tried searching on the net (i was looking for the human ones), all i ever ended up with traced human evolution at best from the primate stage forwards......could not find anything beggining at a uni-cellular organism

[noz92]

thanks

Here's one more that may be of interest.
Although I may just keep on adding more and interesting phylogenetic graphs here.

does anybody know where i can find a complete copy of the ladder of evolution? or does anybody know the complete ladder?

the ladder of evolution should have died when darwin wrote origins, it simply doesn't exist. The correct term is cladogram, and it is more like a bush. There are no "higher or lower" forms, just forms that are adapted to their niche, or becoming extinct.

True, if the fossil gaps were much smaller than they are, it would have been possible to make one very large and complex tree.

thanks for the hyperlinks (again).

Xenoturbella bocki is a worm. It is the most primitive existing member of the group to which humans belong, called the deuterostomes. This is what we evolved from 500 million years ago, as did all mammals, fish, starfish and worms.

You might search, then, at two stages : pre- and post- Xenoturbella bocki.
