hi. an interesting question: according to evolution fly and mosquito split off about 250 my ago. fly generation is about less than one month. so even if one generation mean only 1 new mutation we will need only 10^8 month to change his entire genome. or about less than 10^7 years. so fly and mosquito are suppose to be different in about their entire genomes from each other. far from reality.

The high rate of mutations you propose does not need to occur in to achieve the observed diversity, esp. in sexually reproducing organisms. There is strong pressure for stability for genes that penetrate to expression; due to the fact that its likely any particular genetic mutation that occurs in an offspring may be deleterious to an organisms survival, thus, causing most many mutations to never be passed down. For this reason, dramatic evolutionary changes in genomic groups tends to occur in "fits and spurts", in response to changes in the environment. The most dramatic changes to the environment, such as separation of once-unified land masses, meteor strikes, volcanic eruptions, will tend to result in correspondingly dramatic changes to genomic groups. That is: mutations suddenly have more potential than before. Or, in the case of a two groups of the same species becoming isolated from each other, certain types of mutations that would have been "diluted" out within a few generations of interbreeding (think red hair and black hair humans) may become the norm (certain areas of northern Europe have extremely high concentrations humans with having red hair.

terry good eye I didn’t think that until I looked at this comment

Put that thing back where it came from or so help me!

@@domingopablo9613 The FitnessGram™ Pacer Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The 20 meter pacer test will begin in 30 seconds. Line up at the start. The running speed starts slowly, but gets faster each minute after you hear this signal. Ding A single lap should be completed each time you hear this sound. Ding Remember to run in a straight line, and run as long as possible. The second time you fail to complete a lap before the sound, your test is over. The test will begin on the word start. On your mark, get ready, ding

why senior year? I was a grad of 2020... and no graduation ceremony :( I'm now in college which is all virtual.

@@abigailf.6212 awww I'm so sorry that's the only terrible thing about that and I hope they somehow pay u back for that it's a very special moment❤️

Kellen Willliams welp I was homeschooled, the program I was with wasn’t able to do it, so probably not :(

please come back alive

Woah😊

This comment was uploaded 5 years ago. Ive got an ap bio exam tomorrow and I’m curious to know how you did in the college board exam 😭

What the crap does this have anything to o with his video????? STOP TRYING!!!!!!

I saw that too!! Was a fun little thing to add

How did that to?

kittycat123e phylogeny is the study , cladogram is used in studying characteristics

birds and bats do have common ancestor. but it was not that recent, their common ancestor was some sort of amniote like 300 million years ago, before they split into sauropsids and synapsids they looked like small lizards that evolved from their amphibious ancestors. but it was not flying. and i dont know which color it was.

if you respond to this after 7 years you are a legend
