But with the discovery that birds descended from one branch of the dinosaur family tree, and the unearthing of the first feathered dinosaurs a couple decades ago, some people — researchers, artists and ordinary dino-philes — have taken the whole Big Birdosaurus thing Way. The thinking was (and still is) that feathers first evolved in dinosaurs not for flight or showy peacockery displays but for insulation.
Smaller animals don’t generate as much body heat, so they need more insulation — in this case, more feathers.
I loafe and invite my soul, I lean and loafe at my ease observing a spear of summer grass.
My tongue, every atom of my blood, form'd from this soil, this air, Born here of parents born here from parents the same, and their parents the same, I, now thirty-seven years old in perfect health begin, Hoping to cease not till death.
Feathers are an advanced, or derived trait, and derived traits, once established, usually (but not always) stick with an evolutionary lineage. There is a big difference between a tyrannosaur: humans versus humanoids in every cheesy sci-fi show ever, or hominins (us, and our immediate evolutionary kin) and hominoids, which include all the hominins plus apes, chimpanzees and orangutans.
There is quite a difference in furriness between us and our closest living relatives, bonobos and chimps, and we’ve only been separated from them, genetically speaking, for a few million years.
Or it might have evolved some compensating method of heat loss that we don’t have any clue about based on the fossil record.” Show Me Some Skin The team’s detailed analysis of existing specimens of later tyrannosaur skin revealed that it resembles that of duckbilled dinosaurs, which are not closely related.
There are numerous fossilized skin samples sitting in museums and identified as belonging to duckbilled dinosaurs, but it may be time for a rethink on that, too.
The team concluded that, while at least some of the early tyrannosauroids (like later tyrannosaurids lost the fine feathers of their distant, more primitive tyrannosauroid ancestors.
(Note: we can’t say tyrannosauroid A is the direct ancestor of tyrannosaurid B because the fossil record is just not that complete, but it’s similar to looking at modern humans and then back at, say, the australopiths such as Lucy and South Africa’s Little Foot.
Bigger animals generate more body heat and would be more concerned with shedding it to avoid overheating.Tags: Adult Dating, affair dating, sex dating
