No. Non-avian dinosaurs were extinct about 65 million years ago, as the most recent dinosaur bone was directly dated as being 64.8 ± 0.9 Ma old. The second dinosaur bone sample from Paleocene strata just above the Cretaceous-Paleogene interface yielded a Paleocene U-Pb date of 64.8 ± 0.9 Ma, consistent with palynologic, paleomagnetic, and fossil-mammal ...

Has tuff found amongst the deposits at the Dinosaur National Monument? Yes. The most famous section of the rocks in Morrison Formation in Dinosaur National Monument, the Brushy Basin Member, is chock full of volcanic ash beds that have long since been converted to rock (1, 2, 3). It's also chock full of dinosaur fossils, which is what makes it so famous. ...

Their claim is incorrect. On an astronomical scale, one kilometer is a very small value. In fact, Earth's orbit regularly varies by far more than 1km. According to the NASA's Solar System Exploration website's facts and figures, Perihelion (closest) Metric: 147,098,291 km Imperial: 91,402,640 miles Scientific Notation: 1.47098 x 108 km (0....

The Goldilocks zone ("Circumstellar habitable zone") is a real thing: In astronomy and astrobiology, the circumstellar habitable zone (CHZ), or simply the habitable zone, colloquially known as the Goldilocks zone, is the region around a star within which planetary-mass objects with sufficient atmospheric pressure can support liquid water at their ...

According to a Nature article from 1998 this is true (or at least, was in 1998). Coelacanths were known for decades, but only as fossils. They appeared in the fossil record around 370 million years ago, had their heyday in terms of species diversity around 220 million years ago, and went into a long sunset that appeared to end with extinction, around 70 ...

Yes, Patrick Matthew recognized and published the basics of evolution by natural selection prior to Darwin. It is also well-known that Alfred Russell Wallace independently developed the same theory apart from, but at the same time, as Darwin. Neither Matthew nor Wallace, however, devoted a lifetime to researching and publishing a ground-breaking, full ...

There is a simple factual response based on the fossil record, "No. Dinosaurs and people did not coexist" but this does not really answer the question "did humans draw dinosaurs?" -- with the implicit assumption that the two coexisted. Here I will provide some commentary about cave drawings (petroglyph, pictogram) with sources for further reading. First a ...

This answer has three sections: Is human intelligence declining? No. Is the genetic foundation of human intelligence eroding? This has not been shown. Are other factors influencing the genetic component of intelligence? Probably. Is intelligence declining? No, human intelligence is not declining. In fact, it is increasing. This is actually stated in the ...

This is a fairly common objection to evolution, that appears in various forms. There is a good answer here. It can be generalised to this: Given a biological structure made up of a specific arrangement of a large number of substructures how likely is it that this particular arrangement could be formed by picking the substructures at random? Where the ...

The Rhesus factor is due to a particular mutation and is a gene which derives from our common ancestors with chimpanzees and gorillas: The human RH locus is responsible for the expression of the Rh blood group antigens. It consists of two closely linked genes, RHD and RHCE, that exhibit 92% similarity between coding regions. These observations suggest ...

Yes. Homo sapiens is, as far as we know, the only species that has permanently enlarged breasts. In the rest of the primates, plump breasts last only as long as breastfeeding does: Humans are the only primate to have breasts that are enlarged at all times, in contrast to other primates which have swollen breasts only when breastfeeding. This ...

In A Source Book on Chinese Philosophy, Wing-Tsit Chan remarks of Chuang Tzu (page 177), All this is a direct product of his concept of Nature. To him, Nature is not only spontaneity but nature in the state of constant flux and incessant transformation. This is the universal process that binds all things into one, equalizing all things and all opinions. ...

The BBC article is based on this recent paper: Cliff-edge model of obstetric selection in humans that was published in October 26, 2016. It is a bit too soon to see what post-publication peer-review will say about this, but noted Skeptic and evolutionary biologist, Professor P.Z. Myers has posted at his Pharyngula blog: the paper doesn’t show a causal ...

Ellis Silver takes a number of features of human physiology, claims they are inexplicable by evolution, and comes to the extreme conclusion that aliens placed humans on Earth. However, each of the features are actually prosaically explained by evolution. For example: Bad backs - The Daily Telegraph (A terrible source, I admit, but I only have to do ...

Given the proposed mechanism of evolution (rather than the creationist parody of it) there has been plenty of time. When Darwin was proposing his theory of evolution and long before the molecular basis of inheritance and biological structure were fully understood, he expressed concerns that the mechanism might struggle to explain some complex biological ...

The hypothesis that humans descended from chimp-pig hybrids can be denied on the following points. Hybrids between different orders of mammals are very rare due to the genetic differences and differences in chromosome number. Despite McCarthy's suggestions to the contrary, reports of hybrids between different orders of mammal, though, are, literally, ...

I have been unable to find papers that make an estimate of the total amount of time required for the complete evolution from the LUA. However, I can cite a couple of important papers which show that some of the more complicated steps can be achieved in timescales that are relatively short. The 1994 paper, (A Pessimistic Estimate of the Time Required for ...

This varies by country. For international information see European Christians are at the forefront in accepting evolution: results from an internet-based survey Evolution & Development, 12 (6), 537-540: It was found that almost 60% of Christians believe in creationism and less than 10% believe in natural evolution. The majority of Christians ...

Yes, on both counts. This is based on a newer version of the same Pew survey DavePhD used (his was from 2007, mine from 2014). The new version directly provides numbers for the first question rather than having calculate it from other numbers. For the first question, the percentage of Christians agreeing with the statement is as follows (for humans): ...

There was a very detailed evolution/creation survey done in September 2010 across numerous counties. This is only one time point, but by comparing the views of younger people to older people in certain countries a shift away from evolution is seen. The format of the survey was that people age 16-64 were asked: There has been some debate recently ...

This question is answered by research conducted by Richard Steckel [2] taken from military records, and data on skeletal remains [1] .. analyzed skeletal data from 30 previous studies. The bones had been excavated from burial sites in northern European countries, including Iceland, Sweden, Norway, Great Britain and Denmark. In most cases, the length ...

More recently than the other answers Pope Francis gave an address to the Pontifical Academy of Sciences on 27 October 2014 ... When we read the account of Creation in Genesis we risk imagining that God was a magician, complete with an all powerful magic wand. But that was not so. He created beings and he let them develop according to the internal laws ...

I'll avoid trying to define what "additional genetic information" means and focus on what the Lenski experiment actually shows. The claim from Ken Ham that an existing gene was switched on is essentially correct, although there is a bit more to the whole thing. The genetic background for the evolution of the Cit+ trait is examined in Detail in the paper "...

There is evidence of the opposite. Here are some comprehensive references that based on genetic evidence show how actual human evolution probably happened. Some basics: Pääbo, 2003. Stringer, 2012 comments on what makes modern humans human - of course without mentioning members of the Suidae family. Finally, the introduction of Harris and Nielsen, 2016 ...

Yes, there's some alien hunting going on. Detection Well, yes, money is being spent to search for intelligent aliens. The obvious case is SETI, the Search for ExtraTerrestrial Intelligence. Quoting from their mission statement, Our mission is to explore, understand, and explain the origin and nature of life in the universe, and to apply the knowledge gained ...

It is true to an extent, because you can't really draw a line between nature and culture. I don't think there's a definite answer to this question, but I'll try to share some theories around it. From an evolutionary point of view, female hominids have always invested a big part of their time and energy in their offspring's survival. Our babies take a very ...
