Fugle nedstammer fra dinosaurerne.

Fugle nedstammer fra dinosaurerne. Lige denne teori er meget populær hos mange forskere. Hvordan kom fuglene til, det er spørgsmålet der prøver at blive besvaret i denne her artikel. Det siger at da dinosaurerne forsvandt for cirka 65 millioner år siden, der blev det så fuglenes svar på big bang. Udviklingen fra dinosaurer til fugl skulle siges at være på spil her. Et dansk forskerhold sat fokus på fuglenes ellers rodede stamtræ. Forskere kigger på hvilke dyr der først fik fjer og hvem der først kom på vingerne. Vores undersøgelse prøver at se på hvilke gener fra forskellige fugle, der også kan ses på dyr som levet under dinosaurernes tid eller i hvert fald har gener fra dinosaurerne.
Til undersøgelse har man anvendt programmet Mega 6 som bruges til at iagttage forskellige DNA sekvenser fra dyr også sammenligne dem med hinanden. Undersøgelsen prøver at se om der genetisk sammenhæng mellem de forskellige arter.
Ud fra vores arbejde med generne fra forskellige dyr så er vi kommet frem nogle resultater. Vi har taget DNA sekvenser fra 4 dyr. En Dompap(Fugl), en Skarv(fugl), en Båndvaran(øgle) og en Spidskrokodille. Vi kiggede så på om man kunne drage paralleller på generne hos de 4 dyr. Resultaterne fra undersøgelse var ret positivt, overaskende mange gener var faktisk de samme selvom de kommer fra forskellige arter og slægter. Det følger så teorien om at fuglene stammer fra dinosaurerne og de må har været årsagen til at fuglene kom til.

Birds are descended from dinosaurs. Just this theory is very popular with many researchers. How did the birds to, that is the question that tries to be answered in this article here. It says that when the dinosaurs disappeared for about 65 million years ago, was it so the birds ' response to the big bang. The evolution from dinosaurs to birds should be said to be at stake here. A Danish research team focused on the birds ' otherwise messy family tree. Researchers are looking at the animals that first got the feathers and who first came on the wings. Our study tries to look at which genes from different birds, who also can be seen in animals that lived during dinosaurernes time or at least have genes from the dinosaurs. The study has used the program Mega 6 which is used to observe different DNA sequences from animals also compare them with each other. The study tries to see if there are genetic correlation between the different species.From our work with genes from different animals so we arrived some results. We have taken DNA sequences from the 4 animals. A Crossbill (Bird), a Cormorant (bird), a tape monitor lizard (lizard) and a pointed crocodile. We then looked at whether we could draw parallels on the genes of the 4 animals. Results from the study were fairly positive, over the appearance of many genes were actually the same even though they come from different species and genera. It follows then the theory that birds are derived from dinosaurs and they must have been the reason why the birds came to.

The study has used the program Mega 6 which is used to observe different DNA sequences from animals also compare them with each other. The study samples to see if any genetic relationship between species.
Based on our work with genes from different animals so we come to some results. We have taken DNA sequences from four animals. A Bullfinch (Bird), a cormorant (bird), a Båndvaran (lizard) and a peak Crocodile. We looked looked at whether one could draw parallels to the genes of the four animals. The results from the survey was fairly positive, overaskende many genes were actually the same even though they come from different species and genera. It follows the theory that birds are derived from dinosaurs and they must have been the reason that the birds came.
