Introduction What is a transitional fossil? The term “transitional fossil” is used at least two different ways on talk. I call these two meanings the “general lineage” and the “species-to-species transition”: This is a sequence of similar genera or families, linking an older group to a very different younger group. Each step in the sequence consists of some fossils that represent a certain genus or family, and the whole sequence often covers a span of tens of millions of years. A lineage like this shows obvious morphological intermediates for every major structural change, and the fossils occur roughly but often not exactly in the expected order. Usually there are still gaps between each of the groups — few or none of the speciation events are preserved. Sometimes the individual specimens are not thought to be directly ancestral to the next-youngest fossils i. However, they are assumed to be closely related to the actual ancestor, since they have intermediate morphology compared to the next-oldest and next-youngest “links”. The major point of these general lineages is that animals with intermediate morphology existed at the appropriate times, and thus that the transitions from the proposed ancestors are fully plausible.

The first ancestors of fish may have kept the larval form into adulthood as some sea squirts do today , although this path cannot be proven. Vertebrates , among them the first fishes , originated about million years ago during the Cambrian explosion , which saw the rise in organism diversity. Pikaia had a primitive notochord , a structure that could have developed into a vertebral column later.
Unlike the other fauna that dominated the Cambrian, these groups had the basic vertebrate body plan: The first jawed vertebrates appeared in the late Ordovician and became common in the Devonian , often known as the “Age of Fishes”. The Devonian also saw the rise of the first labyrinthodonts , which was a transitional between fishes and amphibians. The colonisation of new niches resulted in diversification of body plans and sometimes an increase in size.
The Devonian Period to Ma brought in such giants as the placoderm Dunkleosteus , which could grow up to seven meters long, and early air-breathing fish that could remain on land for extended periods. Among this latter group were ancestral amphibians. The reptiles appeared from labyrinthodonts in the subsequent Carboniferous period.
The anapsid and synapsid reptiles were common during the late Paleozoic , while the diapsids became dominant during the Mesozoic. In the sea, the bony fishes became dominant. The later radiations, such as those of fish in the Silurian and Devonian periods, involved fewer taxa, mainly with very similar body plans. The first animals to venture onto dry land were arthropods.

Evidence for Creation A question many people have about the Flood is how did both freshwater and saltwater fish survive? Individual fish from most species will die if placed in a wrong environment. Fish obviously survived—but how? To make matters worse for fish, the Flood certainly involved tectonically induced tsunamis sometimes called tidal waves —incredibly energetic shock waves in the ocean that traveled at great speeds and pummeled the land with towering walls of water.
Fish are very sensitive to shock. Likewise, the Flood involved underwater mudflows, which even today are known to flow at up to miles per hour, following an underwater earthquake or other disturbance. But what about the fish and other marine creatures? How could they survive, particularly both fresh and saltwater forms?
Unlike carnivorous fish, tilapia can feed on algae or any plant-based food. This reduces the cost of tilapia farming, reduces fishing pressure on prey species, avoids concentrating toxins that accumulate at higher levels of the food chain and makes tilapia the preferred “aquatic chickens” of the trade. Like other large fish, they are a good source of protein and popular among artisanal and commercial fisheries. Most such fisheries were originally found in Africa , but outdoor fish farms in tropical countries, such as Papua New Guinea , the Philippines , and Indonesia , are underway in freshwater lakes.

So suggests new research that tracked changes in two genes thought to help regulate brain growth, changes that appeared well after the rise of modern humans , years ago. That the defining feature of humans — our large brains — continued to evolve as recently as 5, years ago, and may be doing so today, promises to surprise the average person, if not biologists. Lahn and colleagues examined two genes, named microcephalin and ASPM, that are connected to brain size.
If those genes don’t work, babies are born with severely small brains, called microcephaly. Using DNA samples from ethnically diverse populations, they identified a collection of variations in each gene that occurred with unusually high frequency. In fact, the variations were so common they couldn’t be accidental mutations but instead were probably due to natural selection, where genetic changes that are favorable to a species quickly gain a foothold and begin to spread, the researchers report.
Lahn offers an analogy: Medieval monks would copy manuscripts and each copy would inevitably contain errors — accidental mutations. Years later, a ruler declares one of those copies the definitive manuscript, and a rush is on to make many copies of that version — so whatever changes from the original are in this presumed important copy become widely disseminated. Scientists attempt to date genetic changes by tracing back to such spread, using a statistical model that assumes genes have a certain mutation rate over time.
For the microcephalin gene, the variation arose about 37, years ago, about the time period when art, music and tool-making were emerging, Lahn said.

Experiments, analysis and stories of the online dating scene. Thursday The Unsatisfied Women of Plenty of Fish I’ve been searching around various different blogs lately trying to find different people’s experiences in using PlentyofFish. Lately, I’ve been stumbling across some blog posts by some women who are out in the dating scene looking for potential male suitors.
Unfortunately, it seems like a lot of disappointment in the men on the site. And for the most part, these men are making a lot of the common mistakes that I’ve mentioned repeatedly on this very blog. Lets take a further look at two of these examples, shall we? The Saving Diva Saving Diva setup a Plenty of Fish profile and has commented that she receives many short lame messages containing such subject lines as Hi, cute pic, etc. Is this how all online dating sites are?
Transitional Vertebrate Fossils FAQ: Part 1A
The first appearances of the ichthys symbol in Christian art and literature date to the 2nd century AD. The symbol’s use among Christians had become popular by the late 2nd century, and its use spread widely in the 3rd and 4th centuries. For example, Orpheus was described as a “fisher of men” as early as the 3rd or fourth century BC. The fish was sacred to the goddess Atargatis , for example, who was said to cause tumors in those who ate them.

Important We believe any unbiased reader will realize that we were fair with our treatment of the two models in the table above. Yet, although the theory of evolution matches the facts in some cases, evolution is still an unproven theory. By now, you may believe it should be your first choice also. Unlike many others that preceded us, we attempted to find a clear defense of evolution for two reasons: To keep from being accused of bias.
To keep from making claims that someone could refute later. Even though there are a great number of claims in books and on the Internet, we could find no scientific, testable facts that support the theory of evolution. The best site we could find was at The University of California at Berkeley. If you are interested, click here to examine the scientific evidence recorded at UC Berkeley yourself.

Matt is a professional painter sharing house painting tips and product reviews. Plenty of Fish and Okcupid were the first dating sites I ever used before they were available as an app. I rarely use either site now, but I will share the pros and cons of both, based on my experience using these apps extensively in the past. I can’t say one site is better than the other. Plenty of Fish has a much larger user base, but sometimes one site will produce better results than the other.
Using both sites is best, but Okcupid has changed, removing features that were once free and making them available only as a paid upgrade. The site is still free to use, but you can no longer see who viewed your profile unless you upgrade. There are premium upgrade options available, but the site is completely free to use otherwise, including sending and receiving messages.
Unless you live in a rural area, you won’t have a shortage of people to message. The site was around long before dating apps and it’s still one of the largest free dating sites on the Internet. The app has a swiping feature similar to Tinder. See who viewed your profile for free.
