The Colorado River carved out a deep canyon in the habitat of an Abert’s squirrel population. This is an example of which stage of speciation? Question 3 options: The populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring. The populations successfully interbreed. The populations become totally separated from one another. The populations are isolated and thus do not interbreed.

Answers

Answer 1

The correct answer is the populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring.

A species is a populace whose participants can interbreed and bring fertile offspring. Reproductive isolation takes place while a populace splits into corporations and the 2 populations now do not interbreed. When populations grow to be reproductively isolated, they could evolve into separate species.

What is speciation?

Speciation is the evolutionary manner via way of means of which populations evolve to grow to be awesome species. The biologist Orator F. Cook coined the time period in 1906 for cladogenesis, the splitting of lineages, rather than anagenesis, phyletic evolution inside lineages.

Hence concluded that the populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring.

Que características poseen los babuinos que no poseen los Lemures

Answers

Answer:

Opposing thumbs, expressive faces, complex social systems: it's hard to miss the similarities between apes and humans. Now a new study with a troop of zoo baboons and lots of peanuts shows that a less obvious trait -- the ability to understand numbers -- also is shared by humans and their primate cousins.

"The human capacity for complex symbolic math is clearly unique to our species," says co-author Jessica Cantlon, assistant professor of brain and cognitive sciences at the University of Rochester. "But where did this numeric prowess come from? In this study we've shown that non-human primates also possess basic quantitative abilities. In fact, non-human primates can be as accurate at discriminating between different quantities as a human child."

"This tells us that non-human primates have in common with humans a fundamental ability to make approximate quantity judgments," says Cantlon. "Humans build on this talent by learning number words and developing a linguistic system of numbers, but in the absence of language and counting, complex math abilities do still exist."

Cantlon, her research assistant Allison Barnard, postdoctoral fellow Kelly Hughes, and other colleagues at the University of Rochester and the Seneca Park Zoo in Rochester, N.Y., reported their findings online May 2 in the open-access journal Frontiers in Comparative Psychology. The study tracked eight olive baboons, ages 4 to 14, in 54 separate trials of guess-which-cup-has-the-most-treats. Researchers placed one to eight peanuts into each of two cups, varying the numbers in each container. The baboons received all the peanuts in the cup they chose, whether it was the cup with the most goodies or not. The baboons guessed the larger quantity roughly 75 percent of the time on easy pairs when the relative difference between the quantities was large, for example two versus seven. But when the ratios were more difficult to discriminate, say six versus seven, their accuracy fell to 55 percent.

That pattern, argue the authors, helps to resolve a standing question about how animals understand quantity. Scientists have speculated that animals may use two different systems for evaluating numbers: one based on keeping track of discrete objects -- a skill known to be limited to about three items at a time -- and a second approach based on comparing the approximate differences between counts.
