We have, multiple times.
"No" transitional ones is completely false and is claim made over and over again. It is *wrong*.
Read the links in this section on fossils to find out why you are totally wrong. It is incredibly annoying that creationists continue to lie about this.

Fascinating link Soggy. Here is a brief snippet from same:
"There are transitional fossils within the Cambrian explosion fossils. For example, there are lobopods (basically worms with legs) which are intermediate between arthropods and worms (Conway Morris 1998)"
And how do evolutionists know they are transitional? Simple, because they are. Did they actually witness the transition between worms and arthropods? No. But they know it happened. That's not science, it's faith. The Church of "Science"-ology.
Well, no. The conditions for fossils to form are rare and finding those fossils is even rarer. Transitional animals only exist for short periods of time, thus the odds of them being fossilized is very low. Even with all this, we have transitional fossils.
Shouldn't there be a bunch of them? Of course not, and because there is not, the great and dead SJG devised the fantasy of punctuated-equilibrium to explain the lack of transitionals.
Please read the dang thread...it has been done to death.

Yes we can. It has been experimentally tested in labs. Before perpetuating more lies, please go back and read the thread, especially Warthaug's posts as he does this for a living.
