Such expressions as that famous one of Linnæus, and which we often meet with in a more or less concealed form, that the characters do not make the genus, but that the genus gives the characters, seem to imply that something more is included in our classification, than mere resemblance. I believe that something more is included; and that propinquity of descent,—the only known cause of the similarity of organic beings,—is the bond, hidden as it is by various degrees of modification, which is partially revealed to us by our classifications (Darwin, 1859, p. 413f).

Australian Postgraduate Award in Biogeography Available at UNSW


An Australian Postgraduate Award (APA) is available for a PhD in the Biogeography Lab of Dr Malte Ebach at the School of Biological, Earth and Environmental Sciences, University of New South Wales. The Biogeography Lab investigates the biotic evolution of Australasia and the geographical and geological processes responsible for biotic diversification over time. We seek a highly motivated student with a good honours or Masters degree in biology/ evolutionary biology or geology/palaeontology to choose from two projects:

1. Evolution and biogeography of water-bugs of Eastern Australasia

This project, in collaboration with Professor Gerry Cassis (UNSW), examines the morphological and molecular systematic relationships of selected endemic taxa of water-bugs (Gerromorpha and Nepomorpha) in Australasia and the relationships between the biotic areas they inhabit. The broader project investigates the biotic evolution of Australasia and the geographical and geological processes responsible for biotic diversification. Requirements: Interest in evolutionary biology, taxonomy, biogeography, field work and natural history. Experience in either systematics, biogeography and molecular techniques would be an advantage.

2. Palaeozoic biogeography and trilobite evolution

This project, in collaboration with Dr John Paterson (UNE), investigates the systematic biology of Carboniferous trilobites (Proetida) and their evolutionary relationships in order to infer palaeogeographic and tectonic reconstructions. The broader project investigates the biotic evolution of Australasia and the geographical and geological processes responsible for biotic diversification.

Requirements: Interest in palaeobiology, palaeobiogeography, field work and natural history. Experience in either sedimentology, biostratigraphy and taxonomy would be desirable.

Please note that applicants must be a citizen or permanent resident of Australia.

Please direct all enquiries and applications to Dr Malte Ebach (mcebach@gmail.com).

Darwin came from Essex (via Peru) says cat's DNA

From the Wollongong Herald

The DNA recovered from Charles Darwin's cat has proven that the 19th century naturalist was descended from South American Indians.

The aspirant Find-an-Ancestor Project uses the DNA from celebrity pets to map human origins. Tiddles, Charles Darwin's first tabby, is one of 30 exhumed ex-pets. "We'd never thought we'd find Tiddles, or any of the 10 cats Darwin owned during his life" says Prof. Trevor Bruce of the University of Ulladulla".

Research funded by the Geelong Anti-ageing Centre tested Tiddle's preserved DNA and discovered that Darwin's ancestors came from a small village in present-day Peru. From there they travelled directly to Essex, possibly via a land bridge made of ice, or by small raft, from France. "The evidence is astounding" says Prof. Bruce, "it is amazing how much information one can extrapolate from DNA".

Tests have led scientists to propose the 'Out of Anywhere hypothesis'. Prof. Bruce explains: "Look, it doesn't matter whose DNA you have, people just seem to originate anywhere. We had the late Liberace's budgie examined and found out that 'The Glitter Man' was descended from Eskimos".

Further research hopes to discover the centre of origin for all humans. Dr. Karen Hall hopes that this will herald a new hypothesis. "Palaeoanthropologists say that humans and apes originated in Africa. Show me one celebrity with a pet gorilla!"

You can participate in the Find-an-Ancestor Project by sending $120.00 for a 'detection kit'. The kit includes a swab and a shovel for extracting pet DNA.
