SPLATS about biogeography
The principles of biogeography
- Around 400, St Augustine considered the distribution of the animals after Noah's flood, and suggested that either men or angels must have transported them.
- Science cannot sustain the view that there ever was a flood like Noah's, and so does not consider this distribution puzzle as a real problem.
- In 1860, Alfred Russel Wallace described the boundary between the Australian and Oriental faunal regions, now usually called the Wallace line or Wallace's line.
- The Wallace's line follows a deep-water channel which runs between Kalimantan and Sulawesi, and between Bali and Lombok, dividing Indonesia into two zones.
- In 1859, Asa Gray suggested the north American and Eurasian floras had once been homogeneous, then separated by Pleistocene glaciation and by later evolution.
- Lydekker's line and Wallace's line are examples of biogeographic boundaries that mark the limits of ancient zones of evolution and the spread of various taxa.
- Evidence for evolution is found in biogeography, where related types of land animals such as Old and New World monkeys are found on related land masses.
- Biogeography also reveals lots of useful information about the way the planet's tectonic plates have moved around in the past, carrying life forms with them.
