"Penguins are 10 times older than humans and have been here for a
very, very long time," said Daniel Ksepka, Ph.D., a researcher at the National Evolutionary Synthesis Center (NESCent). Dr. Ksepka researches the
evolution of penguins and how they came to inhabit the African
Because penguins have been around for over 60 million
years, their fossil record is extensive. Fossils that Dr. Ksepka and his
colleagues have discovered provide clues about migration patterns and
the diversity of penguin species.
Dr. Ksepka goes into more depth
about how his research is piecing together the evolutionary puzzle of
penguins and other related bird species.

PODCAST & VIDEO: Engineering Around Extreme Events
Extreme events, such as super floods and hurricanes, are becoming more common, so civil engineers are trying to adapt civil infrastructure such as bridges to these unpredictable and sometimes devastating meteorological events. Engineer Ana Barros discusses how engineering can prepare us for extreme weather events, but also how changing climate and population conditions can affect the ability of infrastructure to hold up over time.
