FTD

Frontotemporal dementia (FTD) is a group of related conditions resulting from the progressive degeneration of the temporal and frontal lobes of the brain. These areas of the brain play a significant role in decision-making, behavioral control, emotion and language.

 And those are some examples:

- socially inappropriate behaviors 
- loss of mental flexibility 
- decline in personal hygiene
- language problems, and movement disorders
- difficulty with concentration and thinking.

1-Natural selection:



is based on differential success in survival and reproduction individuals in a population exhibit variations in their heritable traits, and those with traits that are better suited to their environment tend to produce more offspring than those with traits that are not as well suited. Darwin's grand idea of evolution by natural selection is relatively simple but often misunderstood. To find out how it works, imagine a population of beetles:

There is variation in traits. For example, some beetles are green and some are brown.

There is differential reproduction. Since the environment can't support unlimited population growth, not all individuals get to reproduce to their full potential. In this example, green beetles tend to get eaten by birds and survive to reproduce less often than brown beetles do. 2- Microevolution: change in allele in frequencies population by time.

3- genetic variation: differences among individuals in the composition of their genes or other DNA sequences.

1-evolution: development  or improvement .

2-biotechnology: the genetic manipulation of microorganisms for the production of antibiotics, hormones

3- Genetic engineering : is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms. The techniques involve sophisticated manipulations of genetic material and other biologically important chemicals.
