Melchior:
Do you not understand that 1 and 3 apply equally to Macro-evolution?
Hi,
The journal
Science just named its “breakthrough of the year” as “evolution in action”, citing a number of recent and important studies. Hopefully, the next 10 or 15 years will see this “macro” and “micro” evolution language among popular culture come to an end. From the ABC coverage:
===================
Research into the formation of new species as they evolve to differ from others:
In 2005, scientists found a type of warbler known as the European blackcap that was separating into groups with differing migration patterns.
Another study found European cornborers in the same field dividing into two types, one of which sticks to corn while the other eats hops and mugwort. The borers have developed different pheromones, scent chemicals that help them breed with only their own group.
And formerly ocean-living stickleback fish that were left stranded in lakes at the end of the last ice age have evolved into several different species.
That study was done by David Kingsley of Stanford University, who reported in March that 15 isolated populations of freshwater sticklebacks had all lost their bony armor through mutations in the same gene.
While scientists had previously shown evolution in biochemical processes, such as antibiotic resistance, some critics had argued that it would be impossible to evolve large changes in the forms of natural populations.
“That is obviously false,” said Kingsley. “Sticklebacks with major changes in skeletal armor and fin structures are thriving in natural environments. And the major differences between forms can now be traced to particular genes.”
