I agree, fundamentally they are both “evolution” .
Micro-evolution happens at micro level, such as a slight deviations in the chromosomal sequence over time without affecting the entire DNA sequencing.
Macro-evolution happens at a larger scale, such as the joining of two chromosomes to form a single larger chromosome, drastically affecting the chromosome sequencingsuch as in humans, and is the historic moment where humans split off from the older hominid species.
i.e. ancestor hominids experienced a series of micro evolution resulting in the modern variety of great apes but maintaining 24 pr of chromosomes, whereas a single macro evolutionary mutation in an ancestor hominid fusing 2 chromosomes into one single larger chromosome produced humans.
The human chromosome #2 is a fusion of two separate chromosomes in our hominid ancestor. Thus resulting in a macro evolution of 23 pr chromosomes in human DNA , where all other modern apes still have 24 pr chromosomes in their DNA.
Human Chromosome 2 is a fusion of two ancestral chromosomes
All great apes apart from man have 24 pairs of chromosomes. There is therefore a hypothesis that the common ancestor of all great apes had 24 pairs of chromosomes and that the fusion of two of the ancestor's chromosomes created chromosome 2 in humans. The evidence for this hypothesis is very strong.
