what would it take to create a
new
human species?
changes to DNA?
to have different functions, susceptibility to disease etc.
examples
Neanderthal
GMO --> for crops and CRISPR
supercoiling method
different number of chromosones
type of alleles that are different
banana and chimpanzees both have 48 chromosones
the chromosomes need to be even --> maintain reproductive ability
ensure MR H GREN and basic life functions are preserved
the genes are different
coding sequence
alleles mutations by slight base pair differences
the loci is different
length of DNA
number of base pairs
phenotypically different?
based on natural selection
have to be physically different but not enough to become different species
limit to the changes
look physically different, observable differences --> expression of different alleles
sometimes may not be visible
most likely will happen for a new human species
examples
length of arms
Neanderthal
Definition
: The observable characteristics in an individual resulting from the expression of genes
time?
longer period of time
to create a whole new species
continue the mutation through reproduction
adaptation & natural selection (happens over billions of years)
short period of time
generational mutations
physical isolation?
prevent cross-breeding
specific environments for adaptation
for natural selection to take effect
what makes a new species
be able to reproduce
slight changes in genes
different chromosones
cannot reproduce with different species
make fertile offspring
