I finished the converting of Darwin's book to HTML and loaded it yesterday to my site library. Now I can focus on Neocene ideas. What about singing perches (or...
I just remaind you of two another sea-lakes: Baikal in Asia (the sea- like by its size and depth), and Mishe-Nama in North America (former Hudson Bay, renamed...
... Can they breed in fresh water? I think it is an important restriction for their further evolution. In closed freshwater lake their population may just...
... They can't. They must migrate into estuaries to do it. So, because of it I doubt seriously in their ability to exist in Carpentaria Lake. But in Arafura...
So, let's lift this topic up. Of course, I'll speak about Neocene, the epoch 25 MY in the future. I may imagine worm-tailed pythons, medium-sized ground snakes...
... I agree, certain snakes in the poresent do something similar. ... Birds seem to be good at evolving inflatable sacs to resonate calls, or even for other...
I was discussing the idea of giant futuristic Arthropods with a friend of mine once, and he gave me a novel solution to the problem of growing large. If we...
... Hmmm. What kind of predators? Among arthropods spiders and many other Chelicerata, a part of insects, crabs and centipedes are predators. ... Ah! You...
Asia is the largest continent of the world. It includes various natural zones - from ice deserts of the north to hot deserts of the south and central part, and...
Now I work at the descriptions of water birds of Fourseas living in vast Karakum delta, where the Uzboy River (filled with water again) separates to many...
... For the Jacarta coast, I imagine Mammals that dominate the area now will become extinct. I'm sure smaller mammals would evolve to fill these niches, like...
... I think cormorants mimicking pelicans would definately evolve. I think herons and bitterns would be present, as well as rails and ducks, including Mergus....
... I think filter-feeders may live in salt reservoirs, where there is a plenty of any one kind of food organisms prospering out of competition. In favourable...
... I think any large animals must live in forest. Destroying trees like modern elephants and rhinos, they'll provide smaller ones with the food - large...
... Thalassocorax, the description is prepared. ... Possible, cyprinid fishes. I think also crabs of family Potamonidae (characteristic for Asia now) may live...
And what do you think about any analogues of phasianids in African forests? Afropavo is rarity now, Francolinus species live in plain and mountain areas. And...
... Some species could use the Phasinid tail assembly as a sound producing organ. The tail feathers could be reduced to thick, hollow tubes, which could be...
... In this case the ability to fly is reduced. Maybe, only two or four middle feathers in tail will change. Or covering feathers above tail? I think small...
... I agree, the number of "percussive feathers" would vary from 2 to 4 in the tail. In some more advanced species, they would have percussive feathers in the...
... Sounds good. But drumming and rattling sounds wouldnt be the only sounds available. With development of hooks, knobs and spines projecting from the...
... I don't think so. They may use such sounds in courtship ritual. In this case only males will have this device, and females lack of it will fly better....
