Tidak Runtuhnya Teori Evolusi Dalam 20 Jawaban - Part 1
Berdasar pengalaman selama menanggapi masalah teori evolusi, umumnya kreasionis yang membantah teori evolusi selalu saja membawa dan mengutip tulisan Harun yahya. Mereka tak peduli jika HY bukan ahli di bidang biologi, dan tak punya kompetensi di bidang tersebut.

Thread ini khusus untuk menanggapi karya HY, 'runtuhnya teori evolusi dalam 20 pertanyaan', yang bisa dibilang cukup dasar. Jadi hal-hal di luar itu kemungkinan tak dibahas.

Dari pengantar dulu

Tanggapan:
Teori evolusi tak pernah bicara soal 'kebetulan', kecuali kita mau mengatakan setiap fenomena alami yang terjadi di alam adalah 'kebetulan'. Proses evolusi adalah proses alami yang terjadi di alam. Dan ilmu biologi umumnya memang mengklasifikasikan manusia dalam taksonomi sebagai anggota dari keluarga (gamily) kera besar, dimana anggota keluarga lain diantaranya gorilla, orang utan dan simpanse. Monyet tidak termasuk keluarga kera besar.

Ingat 3 poin penting yg gw bilang kmaren ga?

1. Citation abal2
2. Citation quote mining
3. Citation nabok mukanya sendiri
emoticon-Ngakak

Sumberr liger itu ada 2 opini. Dia cuma ambil opini yang atas tanpa peduli opini yg bawah. Apa itu namanya kalo bukan quote mining? Apalagi opini yg bawah nabok mukanya. Jelas ga diakuin sama dia

Nih gw bawain lengkapnya ya


The finches that Charles Darwin collected in the Galapagos Islands are considered textbook examples of how a single species differentiated into many to exploit different resources. Subtle changes in the size and structure of beaks among the six species of ground finches have been called “evolution caught in the act.” But are they really one species, or several? In Science Smackdown, we let experts argue both sides of the question.

No New Species

The textbooks are wrong, says ornithologist Robert Zink of the University of Minnesota’s Bell Museum of Natural History. The ground finches may seem to be different species, at least with superficial comparison, but they’re stuck in what he calls Sisyphean evolution. “Species kind of get started, but . . . they never make it to the top of the hill,” Zink says.

In a recent paper in Biological Reviews, Zink helps make the case. “None of these ‘species’ are distinct,” he says. The various ground finches don’t differ significantly in ways that usually differentiate bird species, such as plumage patterns or song. Unlike with discrete species, these features aren’t stable and can vary over just a few generations, depending on weather and food availability. Sequences of their nuclear and mitochondrial DNA show little variation and none of the telltale signs that suggest distinct species.

The circumstances in the Galapagos — frequent interisland travel due to short distances between islands and interbreeding — prevent the finches from truly forming distinct species. It makes more sense to classify the birds as a single species of ground finch with ecologically driven variations, Zink says.


Species, Species Everywhere

Princeton-based husband-and-wife evolutionary biologists Peter and Rosemary Grant disagree. They started studying finches in 1973 and have long held that ground finches represent “species before speciation is complete.” (In fact, that’s how they titled one of their papers.) It’s natural that the nascent species would show genetic resemblance, Peter Grant says. Nonetheless, the traditional view that the ground finches make up six species holds up on the basis of breeding behavior and songs.

“It makes no sense to us as biologists studying populations in nature to combine them all into one species,” says Grant. Despite rare hybridization, the finch populations remain behaviorally and morphologically distinct and, according to Grant, are on their way to becoming separate species.



Bisa diliat sendiri bedanya ya.

Ditambah lagi. Zink cuma ngomentarin finch secara khusus. Setau gw ornithologist itu masih berhubungan erat sama evolusi karena ornithologist juga mempelajari bagaimana burung secara genetis berkaitan dengan dinosaurus.

Sementara itu di lain sisi, peter sama rosemary udh mempelajari finch sejak 1973.
