Rooster_DAR Posted March 31, 2007 Share Posted March 31, 2007 For all you science buffs out there, apparently new evidence shows that the demise of the dinosaurs did not allow the proliferation of mammals to produce any ancestral mammals of today. Interesting, I am going to read more on how they came to this conclusion, as many scientists are weary about these claims. It seems they are not claiming that modern mammals arose later and were not related to prehistoric species, except for maybe a very few specimens. Regardless, it's good to see science at work!

quankanne Posted March 31, 2007 Share Posted March 31, 2007 am confused between title and text: are you saying that evidence indicates no link between dino and modern-day mammals (evolutionary), or that the death of dinosaurs had nothing to do with the rise of mammals? :confused: and what are they basing this conjecture on? (now just curious) Link to post Share on other sites
Trialbyfire Posted March 31, 2007 Share Posted March 31, 2007 I'm a little confused too. One theory is that certain dinosaur species evolved into modern day birds. I don't believe there has been any theory connecting mammals with dinosaurs except from the perspective that there may have been some competition over food sources. Is the theory that you're suggesting associated to the evolution of mammals instead? Link to post Share on other sites
quankanne Posted March 31, 2007 Share Posted March 31, 2007 birds? Bats, I could see, but birds? kinda freaky to imagine. But, then again, i'm brain-frazzled right now ... Link to post Share on other sites

Cheers! Loosing ability to link dinosaurs to the mammals of today? Lol Rooster Dar It sounds like the gap between Genesis l: 1 and 2. May hold water. Because Genesis1 vs. 1 says; in the beginning God created heaven and the earth. vs.2 tells us the earth was without form a void and darkness was upon the face of the earth and the spirit of God moves upon the waters. Isaiah 45:18 God did not create the earth without form and void. So in verse one it was... ...in verse two it was not. What are you reading from? Link to post Share on other sites

Author Rooster_DAR Posted March 31, 2007 Author Share Posted March 31, 2007 Had to dig around to find the orignal article, here it is. They are basically saying the extinction of the dinosaurs did not produce a flurry of new species that led to modern mammals, which has been the common belief. http://www.cnn.com/2007/TECH/science/03/28/mammal.evolution.ap/index.html Link to post Share on other sites

Hmmm...sounds interesting. Please keep us updated if you learn anything else. It's like when the scientific community splintered on the Asteroid vs Volcanic eruption theory for the demise of dinosaurs. As it stands, some still believe it was the Ice Age and a tiny group, some virulent disease. Link to post Share on other sites
norajane Posted March 31, 2007 Share Posted March 31, 2007 Yes, this is what I have learned as well. It seems this new finding may be threating that original perception. D'oh! From what I got out of the article, the original concept was that when the dinosaurs died off 65M years ago, it was thought that led to a mammal explosion of new species as they no longer had to compete with dinosaurs for food and dinosaurs were't eating them anymore. But the study - which seems to have supporters and detractors regarding the dates - shows that mammal explosion didn't happen 65 M years ago, the mammals around back then didn't lead to the current mammals we have now (cats, elephants, horses, and people), and the mammal explosions in history actually occurred 100M years ago, and between 55M and 35M years ago (so, significantly before and after the dinosaurs). So now, they don't really know why the second explosion happened and are thinking it may have had to do with climate change and plant life explosions. Link to post Share on other sites
Trialbyfire Posted March 31, 2007 Share Posted March 31, 2007 Ah, okay. I somehow missed the link he posted. Researchers should now look at such things as the rise of flowering plants and a cooling of the worldwide climate to explain why ancestors of present-day mammals took off before the dinosaurs died out, Gittleman said. The cause of the later boom is also a mystery, he said. I can see why this would have some impact. Dinosaurs would be heavily reliant on temperature due to their bodies being similar to reptiles and certain types/abundance of flora. Smaller mammals would be less susceptible to temperature change. Perhaps that's why the primitive mammals weren't necessarily the ancestors of modern mammals due to size, therefore requirement for larger quanitities of flora. Link to post Share on other sites
Tony T Posted April 1, 2007 Share Posted April 1, 2007 For all you science buffs out there, apparently new evidence shows that the demise of the dinosaurs did not allow the proliferation of mammals to produce any ancestral mammals of today. Interesting, I am going to read more on how they came to this conclusion, as many scientists are weary about these claims. It seems they are not claiming that modern mammals arose later and were not related to prehistoric species, except for maybe a very few specimens. More recent theory has it that the dinosaurs were destroyed about 70 million years ago (ending the Jurassic period) along with most other life forms by a giant meteor which crashed in the vicinity of Cancun, Mexico. The massive nuclear collision caused a thick, dark cloud to surround the earth and drop temperatures to intolerably low levels and block all sunlight for thousands of years. It took millions of years for the atmosphere to be restored to a state where higher life forms could emerge and adapt once again. There were some organisms that seemed to last through this period because of adaptation but not many. Lots of people think cockroaches, alligators, hippos, etc. are examples because they appear rather prehistoric. A lot of scientists feel this same scenario will happen again one day....and somebody else will have to come along and invent an operating system for computers. Perhaps some new life form, far different from homosapiens, will emerge at that time to give the earth a new look and a better shot at survival. Link to post Share on other sites
