One of the biggest mysteries of evolution is how species first developed complex vision. Jellyfish are helping scientists solve this puzzle, as the group has independently evolved eyes at least nine ...

Q: What fascinates you about the eye? A: The eye is an absolutely fascinating organ because it's an organ of extreme perfection, as Darwin has called it. We are able to adjust the focus, we are able ...

Prologue : Molecular genesis -- The age of first cellular life -- The age of complex cellular life -- Eukaryotes organize and metazoans arise -- Early animals prepare the ground -- Vision's big bang ...

Scientists found that adult bristleworm eyes grow continuously thanks to a rim of neural stem cells similar to those in vertebrate eyes. This growth is surprisingly regulated by environmental light ...

CAMBRIDGE, MA -- Why did humans evolve the eyes we have today? While scientists can’t go back in time to study the environmental pressures that shaped the evolution of the diverse vision systems that ...

A new study, led by the University of Vienna and the Alfred Wegener Institute in Bremerhaven, shows how the eyes of adult marine bristleworms continue to grow throughout life – driven by a ring of ...

This study from MIT explores eye evolution through AI simulations, uncovering how different tasks shape visual systems and ...

Wild cats showcase a stunning diversity of eye colors, proving a mystery for researchers because most wild species are known to have narrow eye color schemes (usually black, brown or yellow). Eye ...
