... It depends on skin area/body volume ratio. Growing too large such animal may need more oxygen rather than skin area may provide. And food sources, of...
... Tim, the large size is not a problem, but the next question is "Why?". The lake is also oligotrophic, and too large species will have smaller number...
... Oh, I'm sorry. I was talking about the idea of a giant water frog in general, I wasnt referring to your lake-dwelling frog at all. What kind of environment...
... First of all, it needs a supply of oxygen. It means in warm water containing low amount of dissolved oxygen it can not appear. The exception may be old...
Todays subject is asking a question about human anatomy. If humans evolved towards a different size, be it large or small, what modicications would take place...
... I think bipedal construction of the skeleton limits strictly the size increasing - it affects on child birth first of all. I think any dwarf forms may...
... That would mean that the future evolution of human species would contain variations on the current range of human heights. We *could* concievably have...
... I think Dougal Dixon in "Man after man" made all (im)possible variations of human body, except for possible ones. Tim, sooner or later I'll do his "Man...
... But of course, Dixon had his big excuse in that the humans were genetically modified, Nemo Ramjet used the same idea for his modified humans. I think...
... it´s true in the evolutionary history we only know giant frogs in the geological age of the carbonifore or devonic. in a world with other competition...
in my imaginated warm climated future world I use names for some animals, like roc, the mytical giant bird, i asigned it for a giant predatory crow, and...
... Oh, Dougal Dixon's ideas rooted deeply in minds of explorers of the future. Welcome here, electree164! I'm glad to see new members here. Sorry for my...
... Hmmmmmmmmmmmm... Sorry, but first animals-of-the-next-kin-to-frogs evolved only in Triassic. Protobatrachus, or Triadobatrachus was the first known anuran....
... I´m sorry, i comit a great mistake. i´m thinking in the "devil frog" beelzebufo ampinga, a enormous frog(40 cms) from Madagascar, 70 millions of years in...
hi. i´m new in this group and i very gratefull for my welcome. this forum is fantastic and i have to congragulate his creator. yourselves have to forgive me...
... *** The creator of this group is Tim Morris, from Australia. And I'm only "second pilot" here, Pavel Volkov from Russia. ... *** Don't worry. Sometimes I...
You must study the laws, principles and mechanisms of evolution. I read complete the Origin of the especies and i stare at some books, but the knowings that i...
... So, I see some mistakes in your creatures. First, crocoturtle. Turtles lost their teeth at least in Triassic. And you draw your creature having toothed...
... well i created antler like tooth only in males and they usem them only in reproductory seasons, for fights. after that the tooth fall, then they can eat. ...
... Oh, we speak about a little bit different things. I don't ask about the function of their teeth - it is clearly seen. I speak about their shape and growth....
... other problem are the species and the continental ubication, in how much time could my species evolve? i think my world is favourable for 23 or more...
message for anybody. I need a lot of help in the topic of the marine creatures of my world. i have few imformation of the species that could survive at an...
... Exactly what I thought about once! Anyway, I'd made a bizarre world composed of clades that are quite marginal on Earth (gingkos, tuataras, etc.)...
