Ha still alluding to flatworm sex creating mankind, but not brave enough to come out of the closet and say it??Follow the evidence, if you dare.
Tell us what you think we find regarding man resulting from worm sex from following evidence?Be brave, be real, follow the evidence.
Reality is not the issue here. The issue was your admission that you actually believe in your heart that worms had sex and mankind resulted!!!
No need to go further! We get a nice clear look at your true belief from the worm sex created man claim! Science cannot show any so called first lifeform so we can get out teeth into what they call out oldest living ancestor..the flatworm!!!!
No denying that all history led up to the blood of the Lamb of God. They needed to know. It is what life is all about.
Gotta love your guts and honesty.Yes, our oldest living ancestor is the flatworm. Sorry that bothers you. Doesn't make it less true that you don't like it.
Gotta love your guts and honesty.
Now try to get your male evo comrades to fess up.
Right, I know you can't make him man up. You have admitted you believe you came from flatworm sex, that'll do.I am not accountable for his decisions, if he doesn't want to say that, I won't try to make him do it. I will openly assert the evidence we have indicates flat worms to be our oldest living ancestor. Not that any of the species that currently live are the same we descended from, but you get the general point.
And who knows what sort of species will be looking back on us as their ancestor in a few million years, or if any species shall do so.
Perhaps they will find us gross too, whatever.
We get that you believe that. Wish I could help.It isn't like I don't find flatworms gross, I do, especially their freaky cartoon looking eyes, ugh. But they are an ancestor nevertheless.

Like I said to dad, FOLLOW THE EVIDENCE!
Right, I know you can't make him man up. You have admitted you believe you came from flatworm sex, that'll do.
Follow the evidence, if you dare.
You have evidence for flatworm sex producing humans? Realizing this is a family forum, could you give the evidence for this particular creationist view?
You don't do links, so, google flatworms and oldest living ancestor and you will get the information for EVOLUTION and flatworms.
You can do that, can't you?
Ok, back.
Wish I hadn't read some of the stuff on flatworm behavior, while at the same time is was entertaining. Good for a chuckle or two.
This is the evidence that flatworms having sex are our ancestors???
"The flatworms, known in scientific literature as Platyhelminthes or Plathelminthes (from the Greek πλατύ, platy, meaning "flat" and ἕλμινς (root: ἑλμινθ-), helminth-, meaning worm) are a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrate animals. Unlike other bilaterians, they have no body cavity, and no specialized circulatory and respiratory organs, which restricts them to flattened shapes that allow oxygen and nutrients to pass through their bodies by diffusion."I just don't have enough faith to embrace the flatworm creationist view.
A Wiki definition doesn't cut for these purposes just. You bypassed other sources that discuss the topic at hand. That's ok.

Flatworms Are Oldest Living Ancestors To Those Of Us With Right And Left Sides, Reported In The 19 March Issue Of Science
[SIZE=-1]This news release is also available in Spanish. [/SIZE]
Washington DC - A team of scientists from Spain and the UK has determined that a certain curiously primitive group of flatworms are the oldest living ancestors to all "bilateral" animals-that is, those with a right and left side. These worms were previously thought to belong to a much younger group of organisms, and their newfound identity also implies that bilateral organisms began making their debut on Earth earlier than previously thought. The finding is reported in the 19 March issue of Science.
Researchers agree that the first multicellular animals had circular shapes that were "radially symmetrical," just like the jellyfish or sea anemones of today. A crucial step in the evolution of more complex organisms was the transition to body shapes with bilateral symmetry. (For example, most of the features that allow an animal to move itself from one place to another--legs, fins, wings--can only develop on bilateral organisms.) In spite of the major evolutionary importance of this transition, until now scientists have known little about the earliest bilateral animals.
It has generally been thought that most bilaterians arose during a dramatic diversification of animal life (dubbed the Cambrian explosion) 540-500 million years ago. That's because the ancestors of nearly all major modern animal groups, or phyla, made an appearance in the fossil record during this period. However, evidence has been growing that there was an extended and fruitful period before the Cambrian when bilateral organisms may have arisen and diversified. The new study by Jaume Baguñà, of the University of Barcelona, and his colleagues supports this theory by identifying a group of contemporary flatworms called the Acoela as the living descendants of an early lineage from this pre-Cambrian time. (Flatworms, several of which are parasites, are only distantly related to, and much simpler than, the familiar earthworms.)
"It may well be that the origin of bilateral organisms occurred a bit earlier on, [before the Cambrian explosion,] from simple animals whose fossils have not been recovered," said Baguñà. "This may mean that we need to look more carefully at pre-Cambrian rocks or sediments to search for primitive bilateral animals."
Baguñà and his colleagues, Iñaki Ruiz-Trillo and Marta Riutort of the University of Barcelona and D. Timothy J. Littlewood and Elisabeth A. Herniou of the Natural History Museum in London, began their study with the intention of investigating a troublesome subgroup of flatworms that didn't fit neatly into its prescribed classification. The Acoela, as this subgroup is known, are unlike other flatworms for a number of reasons, particularly because they are unusually primitive. For example, other flatworms have digestive tracts of some sort, but the Acoela lack them altogether.
To determine whether the Acoela might not be better classified separately from the other flatworms, Baguñà and his colleagues took a molecular approach. Molecular studies such as this investigate the evolutionary relationships among taxonomic groups, based on the assumption that mutations in a gene occur at a constant rate. Once researchers have determined the sequence of a particular gene, they can compare the gene in a variety of organisms. If the sequences are significantly different, that implies that the organisms are more distantly related. In other words, more time has passed since they diverged from their common ancestor.
The research team sequenced the Acoela's "18S rDNA" gene, which had already been sequenced in many other animals, including other types of flatworms. The scientists then compared this sequence in a variety of animals, using a software program to create an evolutionary road map that showed the most likely relationships among the organisms. According to the results, the Acoela were the first group of organisms to split off from the radial organisms, well before the other flatworms arose in the midst of the Cambrian explosion. The scientists suggest that the Acoela should be classified in their own new phylum.
At some point during the period in which bilateral animals appeared, another important transition took place, this one involving a fundamental change in the way animals developed as embryos. Radial animals are also "diploblastic," meaning their tissues develop from two primary layers of embryonic cells. In contrast, tissues of the more complex "triploblasts" develop from three primary layers of embryonic cells. Because information from the pre-Cambrian is so sparse, researchers don't know yet the details of when or how this other change occurred-they just know that bilaterians were also triploblastic. "The finding of the Acoela well in the middle of the long branch separating diploblasts from triploblasts may be the first item to bridge the gap and to give us a better understanding of how the major body plans emerged," said Baguñà.
