Dna? sadly not. the oldest dna recovered is from a horse bone found preserved in the frozen arctic soil. we know this bone is somewhere around 700,000 years old. this age is kind of critical because this is actually the oldest ice that s known. so dinosaurs went extinct 65 million years ago. between then and now there have been periods in history when there was no ice, it was a very vsh hot planet. that means there s probably no place that dinosaur dna at all survives. what about the frozen mammoths let s go to ice age if we re going to do movies. people do find frozen mammoths right? yes. there are hundreds even thousands of extremely well pre served remains like mammoths mastodons, species that went extinct within the last 20,000 to 50,000 years. mammoths survived we know until around 3,000 years ago on an
Is trapped in amber, a mosquito fossil. using sophisticated techniques they extract the preserved blood from the mosquito and bingo, dino dna. can that happen? what i m about to say is extremely disappointing. we will never clone dinosaurs. the problem is the dna in every single one of our cells does certainly survive after death, but it doesn t survive for very long. in fact how long it survives will vary depending on the environment, preservation cold places are a lot better for preservation than warm places and dry places are better than wet places. it turns out that amber is an extremely poor place for dna to survive. it s porous and bacteria can get in there and chomp up the dna, eat it up until there s nothing else. could there be some place in the arctic where there s dino
Beth shapiro, welcome. thanks for inviting me. first, the jurassic movies have as their original premise, all stem from the basic idea that you can clone a dinosaur. they find a mosquito, i think it is trapped in an embers a mosquito fossil. using sophisticated techniques they extract the preserved blood from the mosquito and bingo, dino dna. can that happen? what i m about to say is extremely disappointing. we will never clone dinosaurs. the problem is the dna in every single one of our cells does certainly survive after death, but it doesn t survive for very long. in fact, how long it survives will vary depending on the environment, preservation. cold places are a lot better for preservation than warm places, and dry places are better than wet places. it turns out that amber is an extremely poor place for dna to survive. it s porous and bacteria can get in there and chomp up the dna, eat it up until there s nothing else. could there be some place in the arctic where there
