How fish evolved their bony, scaly armor
About 350 million years ago, your evolutionary ancestors—and the ancestors of all modern vertebrates—were merely soft-bodied animals living in the oceans. In order to survive and evolve to become what we are today, these animals needed to gain so.....»»
Air pollution particles may be contributing to dramatic drop in global insect numbers
The impact of air pollution on insect health and reproduction is greater than previously understood and could be contributing to global declines in insect populations, including in remote wilderness areas, new research shows......»»
Size does matter: Group size and mating preferences drive deeper male voices
Deeper male voices in primates, including humans, offer more than sex appeal—they may have evolved as another way for males to drive off competitors in large groups that favored polygyny, or mating systems where a male has multiple mates, according.....»»
Study reveals how a tall spruce develops defense against hungry weevils
A study led by a North Carolina State University researcher identified genes involved in development of stone cells—rigid cells that can block a nibbling insect from eating budding branches of the Sitka spruce evergreen tree. The insect's attack ha.....»»
