The origin of human language
2024-09-29 15:54 Some imagine “cavemen” with a very limited language.  If they talk at all people imagine pidgin.  The present-day human species have never talked like that when people spoke their mother tongue.
The origin of humanity
2024-09-27 14:40 I know people don’t like being grouped with monkeys.  However, purely biologically we are.  Our genus (Homo) have only had one species (Homo sapiens) since at least the end of the last ice age.
Famous prehistoric mammals
2024-09-09 13:04 After the Cretaceous–Paleogene mass-extinction it took 15 million years for the world to recover.  Mammals and birds then evolved to take over the role of the dinosaurs.  Towards the end whales arose too take over after the plesiosaurs.
On the Cretaceous–Paleogene mass-extinction
2024-09-02 12:16 The world looked a bit differently 66 million years ago.  Pangaea had splintered into Africa, Antarctica, Australia, Eurasia, North America and South America.  Antarctica was connected to Australia, and Eurasia to North America.
Contemporary with the dinosaurs
2024-08-29 12:25 Plants has changed much since the time of the dinosaurs.  However, not so very much as many imagine.  Mosses, lycophytes and ferns existed long before the dinosaurs.
Real dinosaurs
2024-08-17 19:29 Some perceive dinosaurs as entertainment for children.  Dinosaurs are actually subject to scientific investigation.  As they are described today they make sense to me.  They make as much sense as platypuses, kangaroos and bats.
On the Permian-Triassic mass extinction
2024-08-12 12:53 At the end of the Permian Pangaea was born.  Africa, Antarctica, Australia, South America and South Asia had long held together.  It is probably rather obvious how Africa and South America were stuck together.
Life before the dinosaurs
2024-08-07 16:56 Many imagine the early Earth as covered in molten rock.  Fact is the Earth’s crust solidified within a hundred million year after the birth of the Moon.  200 million years later the Earth was almost completely covered by seas.
The primeval myth
2024-06-13 13:53 I state points in prehistoric times for a good reason.  There is a myth of a vague “primeval time” when everything one knows about lived at the same time.  Then I mean different animals, larger than current ones and more or less strange.
Radioactivity, fission and fusion
2024-04-12 12:52 Radioactivity is about certain elements – or variants of them – in course of time decaying.  Most such which has been found have never been observed to decay.  A smaller fraction has and then emit ionising radiation.
