This study provides empirical evidence of eco-morphological differentiation occurring very quickly after the colonization of a new and vacant habitat. Exceptionally low levels of neutral genetic diversity and inference from coalescence indicates that the Midas cichlid population in Apoyeque is much younger (ca. 100 years or generations old) than the crater itself (ca. 1 800 years old). This suggests either that the crater remained empty for many hundreds of years after its formation or that remnant volcanic activity prevented the establishment of a stable fish population during the early life of the crater lake. Based on our findings of eco-morphological variation in the Apoyeque Midas cichlids, and known patterns of adaptation in Midas cichlids in general, we suggest that this population may be in a very early stage of speciation (incipient species), promoted by disruptive selection and ecological diversification.
Is this it ? Are creationist going to find a weak spot what they can use to deny it's evolution taking place ?
...Of particular interest has been the creature’s origin. Encyclopaedia Britannica says that ‘little is known of their ancestry’ and: ‘Most authorities believe the order Monotremata originated from a line of mammal-like reptiles different from that which gave rise to the other mammals. Nonetheless monotremes may well represent features of anatomy and development that characterized the earliest mainstream mammals.’
Scientists initially considered the platypus to be ‘primitive’, but then they discovered the incredibly complex electrolocation techniques the animal uses to find food. To evolutionists this made it a ‘highly evolved animal and not a primitive transition between reptiles and mammals.’
The platypus, along with its fellow monotreme, the echidna, was believed to have evolved in isolation when the land mass that would become Australia (Gondwana) broke away from the other continents supposedly 225 million years ago. This idea of evolution in isolation followed the theory of Darwin, whose affinity for evolution may also have been influenced by his early studies of the platypus during his time on The Beagle.
However, the discovery in the early 1990s of three platypus teeth in South America—almost identical to fossil platypus teeth found in Australia—threw that theory upside down. (Marsupials, too, were once considered to be exclusive to Australia, but their fossils have now been found on every continent.) Adult living platypuses do not have teeth, but the discovery of platypus fossils in Australia had already identified that their ancestors did have teeth, which were unique and distinctive.
In reality, there is nothing in the fossil record to indicate that the platypus was ever anything other than a platypus. It is not a living ‘transitional’ form. It is a truly unique creature, and one that continues to baffle those who insist on making it fit into an evolutionary tree.
For those not familiar, the coelacanth was once only known from the fossil record. Paleontologists confidently pronounced that it went extinct some 65 million years ago, since no trace of it was found in more “recent” fossil layers. Imagine their surprise when, in 1938, a living coelacanth was found off the coast of Madagascar!..
Nice sensationalist title, though.
