When did wolves become dogs?

What evolutionary and developmental processes are involved in creating physical variation?

Is selection responsible for moulding the diversity of life?

Or does developmental bias via drive and constraint determine how animal shapes change?

Abby Drake is interested in the processes that produce macroevolution and dictate which physical appearances, evolve and which do not.

She is especially interested in learning how species evolve: What mechanisms produce enough physical or behavioural change to ensure reproductive isolation on the population level?

To this end, she studies developmental processes that lead to large modifications of morphology, using variation in vertebrate skulls to answer these questions.

Abby uses three-dimensional scan data to capture each specimen’s 3D geometry.

This type of data allows her team to look at the shape of the skull holistically using a sophisticated shape analysis called geometric morphometrics.

While she also works on cetaceans, owls and primates, this episode focuses on her extensive work examining canids: when did wolves become dogs, how have we shaped them, and where might they go in the future?

Gestures & communication: chimpanzees have a point

How chimpanzees communicate

Imagine deciphering the first form of intentional communication to be recorded in the animal kingdom, such as how chimpanzees communicate.

That’s exactly what Dr. Catherine Hobaiter has done after years of following wild chimpanzees in the Budongo Forest of Uganda, Africa.

She studies the evolution, acquisition and flexibility of communication and social behaviour, in particular through long-term field studies of wild chimpanzees.

For the past seven years, Cat has been working as a primatologist at a forest research-station in Uganda to better understand chimpanzee communication and behavior.

She hopes to to advance our understanding of great ape communication, and in addition, by looking at areas of overlap or species specific traits, she hopes to also gain an understanding of the evolutionary origins of language.

In this episode, we learn from Cat about her exciting observations of a communication system where animals don’t just share information through behaviour, but deliberately send messages of meaning to each other.

Listen in, and you’ll find out exactly how how chimpanzees communicate.

The importance of bees: more than honey

The importance of bees

Ever wondered why you should care about bees?

Here’s a fact: bees are responsible for the successful production of around a third of the food you eat.

As one of our oldest domesticated animals, bees and people share an amazing history.

But the future is uncertain, with devastating global declines in both feral and managed populations.

Boris Baer and Barbara Baer-Imhoof, in conjunction with their colleagues at the Centre for Integrative Bee Research at the University of Western Australia, are researching many aspects of honey bees, in the field and in the lab.

In our first episode featuring an invertebrate species, we learn more about our relationship with bees, what would happen if they vanish and ways we can help them thrive.

Wild behaviour: the science of why cats like boxes

Why cats like boxes

Sandra McCune holds a PhD that examined the temperament and welfare of caged cats as well as qualifications in vet nursing and zoology. She knows the answer to why cats like boxes, and the science behind it.

In her current role as the Scientific Leader for Human-Animal Interaction at the Waltham Centre for Pet Nutrition, she manages a large portfolio of collaborative research projects.

These projects cover many aspects of human-animal interaction, in countries including US, UK, Austria, Germany, Sweden and Australia.

In addition to having written research papers and book chapters on several aspects of cat behaviour, cognition, welfare and nutrition, Sandra has lectured and advised many animal shelters, ethologists, animal welfarists, and groups of vets and vet nurses.

Sandra is sought out as a voice within industry and regularly speaks at international conferences on pet ownership issues and the bond between people and pets.

Today we’re talking to Sandra about pet cats, their incomplete domestication, our attachment to them and the behavioural links between wild big cats, and the cat in your home.

We also find out why cats like boxes!
