Macroevolutionary studies focus on change that occurs at or above the level of species, in contrast with microevolution so you have to explain mutation that ad info above the level of species,with gene duplication. in any duplication of a region of DNA that contains a gene; it may occur as an error in homologous recombination, a retrotransposition and that does not ad information

Good imagination and changing of definitions of Kind

@cyclonus11 A wolf and a coyote don't interbreed. They can because they share a common ancestor. Cattle and bison don't interbreed in nature either.
Creatards think there should be a Crocoduck because they don't understand evolution.

Another example would be the 'Coywolf' - a fertile hybrid between the grey wolf (Canis lupis) and the coyote (Canis latrans).

While I completely agree with the premise of this video, I'm going to point out a major flaw. A species is NOT defined by the ability or inability to interbreed and produce fertile offspring. It is defined by genetic difference, and nothing more; the ability to breed is a result of chromosome and gene alignment during reproduction. Take a look at domestic cattle and the American bison; both are different species (different genus even) and both can produce fertile offspring. Look up 'beefalo'...

@EvolvedAtheist Yeah, idiot! [to kmmaraxus, not EvolvedAtheist]. Do what EvolvedAtheist says!

There are some predictions about what we could be evolving towards. Or what paths various species may evolve towards. However they are all speculative
1) Because mutations are random and cannot all be accounted for
2) Because we do not have perfect predictive models of the future environment
3) Because we do not have a perfect map of all allele frequencies across this and other species.
I'm a skeptic of all. By your definition a female human that can no longer breed means shes the end of her species, or just incapable? Your logic is fuzzy

@kmmaraxus
Your logic is worse than fuzzy. Your non-breeding female would be the end of her species ONLY if she were the LAST female on earth. Think before you type.

So I'm evolutionary illiterate. I'm not going to lie about that. I have to ask though. What is the homosapien or modern human I guess evolving into? Are there any models based on any type of observations that would indicate we are evolving into something else or what we'll be in say 100000 years from now? Also how can we tell a true evolutionary change from a genetic mutation for example?

@exacerbatedtaboo
// evolving into? //
No way to predict.
// true evolutionary change from a genetic mutation //
biological evolution = change in allele frequency in a population = accumulated mutations
deleterious SNP or bigger mutation => disease or death
There are *lots* of excellent videos on the topic of biological evolution on YT.
