New proto-mammal fossil sheds light on evolution of earliest mammals

New proto-mammal fossil sheds light on evolution of earliest mammals

August 7, 2013 A newly discovered fossil reveals the evolutionary adaptations of a 165-million-year-old proto-mammal, providing evidence that traits such as hair and fur originated well before the rise of the first true mammals. The biological features of this ancient mammalian relative, named Megaconus mammaliaformis , were described by scientists from the University of Chicago in the Aug 8 issue of Nature .

‘Head-first’ diversity shown to drive vertebrate evolution

‘Head-first’ diversity shown to drive vertebrate evolution

December 21, 2011 The history of evolution is periodically marked by explosions in biodiversity, as groups of species try out a wide range of shapes and sizes. With a new analysis of two such adaptive radiations in the fossil record, researchers have discovered that these diversifications proceeded head-first.

A small step for lungfish, a big step for the evolution of walking

A small step for lungfish, a big step for the evolution of walking

December 12, 2011 View video of the African lungfish using its thin pelvic limbs to lift its body off the bottom surface to propel itself forward. The eel-like body and scrawny “limbs” of the African lungfish would appear to make it an unlikely innovator for locomotion.

Tiktaalik discovery among National Geographic’s top grants

Tiktaalik discovery among National Geographic’s top grants

December 8, 2011 Neil Shubin’s 2004 discovery of the pivotal fossil Tiktaalik roseae , a transitional species between ancient fish and the first limbed animals, is among 10 projects selected for their historical significance as part of the National Geographic celebration of the magazine’s first 10,000 grants. Since 1890, the National Geographic Society has funded grants to every corner of the planet –unlocking many of its secrets, sometimes in spectacular ways.

Errors in protein structure sparked evolution of biological complexity

Errors in protein structure sparked evolution of biological complexity

May 18, 2011 Over four billion years of evolution, plants and animals grew far more complex than their single-celled ancestors. But a new comparison of proteins shared across species finds that complex organisms, including humans, have accumulated structural weaknesses that may have actually launched the long journey from microbe to man.
