Based on the mutation rate of the molecular clock, it will take 22.5 million years for one full base pair mutation to occur.

<h3>What is a molecular clock?</h3>

A molecular clock is a biomolecule which is chosen to serve as a clock due to its periodical changes in a regular pattern.

Mutation in genes can serve as molecular clock.

The mutation in the gene of coding for the venom mutates at a rate of 0.76 base pairs every 17.1 million years.

It will take 17.1/0.76 = 22.5 million years for 1 base pair to mutate.

Therefore, it will take 22.5 million years for one full base pair mutation to occur.

In 2004, scientists announced the discovery of the fossil remains of some extremely short early humans on the Indonesian island
Alex

Answer: The most accepted guess is: By bamboo rafts.

Explanation:

There are two hypotheses.

The first is that they arrived on Flores as Homo erectus and then evolved to Homo floresiensis. The second is that they were already Homo floresiensis when they arrived. This second one is the more accepted hypothesis because it would take organization and language to accomplish this technological water transportation feat. Homo erectus is not known to have developed speech.

Now at the time this transport was estimated to have happened, 100000 years ago, the islands of Komodo and Flores were joined and visible from the mainland. Together they constituted a 19km wide straight visible that could be easily seen from the mainland. The Homo floresiensis tribes built bamboo rafts, or possibly some other floating apparatus made if wood, and sailed there. The islands then progressively drifted apart, isolating them.

PS: It is important to note that some things may have drove them there such as famine, violence, etc.

tester [92]

Answer:

375 million-year-old fish, a large scaly creature not seen before, that they say is a long-sought "missing link" in the evolution of some fishes from water to a life walking on four limbs on land. In addition to confirming elements of a major transition in evolution, the fossils are widely seen by scientists as a powerful rebuttal to religious

Explanation:

on closer examination, scientists found telling anatomical traits of a transitional creature, a fish that is still a fish but exhibiting changes that anticipate the emergence of land animals — a predecessor thus of amphibians, reptiles and dinosaurs, mammals and eventually humans
