Problems with reproduction in birds

In birds and other species alike, pairs can face considerable difficulties with reproduction. Scientists at the Max Planck Institute for Ornithology in Seewiesen have now shown in an extensive analysis of 23,000 zebra finch ...

Shifts in butterfly mating preferences

In their efforts to identify the genetic basis for differences in mate choice that keep two co-existing species of butterfly separate, evolutionary biologists at LMU have identified five candidate genes that are associated ...

Lungfish fins reveal how limbs evolved

The evolution of limbs with functional digits from fish fins happened approximately 400 million years ago in the Devonian. This morphological transition allowed vertebrates to leave the water to conquer land and gave rise ...

Geneticists zeroing in on genes affecting life span

Scientists believe about 25 percent of the differences in human life span is determined by genetics—with the rest determined by environmental and lifestyle factors. But they don't yet know all the genes that contribute ...

Why the goby can conquer the waters of the world

The round goby, one of the most common invasive freshwater fish in the world, boasts a particularly robust immune system, which could be one of the reasons for its excellent adaptability. This is the result of genome research ...
