Global warming led to dwarfism in mammals -- twice Posted: 02 Nov 2013 06:55 AM PDT Mammal body size decreased significantly during at least two ancient global warming events, a new finding that suggests a similar outcome is possible in response to human-caused climate change, according to paleontologists.

Non-genetic inheritance and changing environments Posted: 01 Nov 2013 06:17 AM PDT In the last two decades climate change emerged as a momentous threat to ecosystems and species, calling for - politics aside - a greater interest in the adaptation abilities of the world's creatures. Understanding and predicting how populations will respond to climate fluctuations has been attracting a wealth of research into evolutionary biology and the molecular components of evolution; with some vital questions motivating these studies: namely, how organisms will handle their new circumstances, or how populations will be able to cope with climate change in order to survive and avoid extinction. With the far-reaching impacts of climate change being felt globally, it is no wonder that scientists are desperate to understand evolution and its implications for adaptation abilities.
