For over 60 years, scientists have theorized that a person's body shape and size could be influenced by the climate of where they live. Now a new study from the University of Tennessee, Knoxville, suggests there's more to ...
There is new evidence that the "mother's curse" - the possibility that moms may transmit genes to their children that harm their sons but not their daughters - holds true in animals.
Spectacular failures to replicate key scientific findings have been documented of late, particularly in biology, psychology and medicine.
It's easy to understand why natural selection favors people who help close kin at their own expense: It can increase the odds the family's genes are passed to future generations. But why assist distant relatives? Mathematical ...
A new study into pythons and boas has for the first time found the two groups of snakes evolved independently to share similar traits, shedding new light on how the reptiles evolved.
An evolutionary framework aiming to track the pathways wild organisms followed to survive and thrive in environments dominated by humans has been developed for the first time.
The same gene that enables tropical butterflies to mimic each other's bright and colourful patterning also caused British moths to turn black amid the grime of the industrial revolution, researchers have found.
A study of butterflies suggests that when a species adapts, other parts of its genetic make-up can be linked to that adaptation, limiting diversity in the population.
How birds' beaks evolved characteristic shapes to eat different food is a classic example of evolution by natural selection.
What are the cause and innate power for the biological evolution? This is a controversial problem from ancient times to now. The interpretation for the evolutionary process is at an ambiguous phase although the academia admitting ...
