Origin of flowers has been discovered

, , ,

Flowering plants emerged on the planet over 160 million years ago – but it has never been entirely clear how these angiosperms came from their predecessor, gymnosperm ferns. New genetic analysis of the Amborella, a shrub with deep evolutionary roots, shows that there was a genomic doubling around 200 million years ago. The results were […]

Origin Of Modern Lions Discovered

, ,

In an attempt to understand the origin and population history of lions, scientists sequenced DNA from both living lions and museum-preserved lions, some of which are now extinct, from different geographical areas. They found that recent lion lineages began to diverge in the Late Pleistocene, and that the modern lion populations last shared a most […]

Algae Study Sheds Light On The Evolution Of Sexes

, ,

In an intriguing new study, scientists discovered that a single gene in multicellular green algae that determines whether the organisms produce sperm or eggs evolved from a primitive form in its unicellular ancestor that does not have separate sexes. The research may therefore hint at how sexes in multicellular organisms evolved from sexless ancestors. The […]
