Fossil does not support bat evolution

Mutations simply produce new varieties of already existing traits. For example, mutations in the gene for human hair may change the gene so that another type of human hair develops, but the mutations won't change the gene so that feathers or wings develop.

Sometimes mutations may trigger the duplication of already existing traits (i.e. an extra finger, toe, or even an entire head, even in another area of the body!). But mutations have no ability to produce entirely new traits or characteristics.

Furthermore, only those mutations produced in the genes of reproductive cells, such as sperm in the male and ovum (or egg cell) in the female, are passed on to offspring. Mutations and any changes produced in other body cells are not transmitted. For example, if a woman were to lose a finger it would not result in her baby being born with a missing finger. Similarly, even if an ape ever learned to walk upright, it could not pass this characteristic on to its descendants. Thus, modern biology has disproved the once-held theory that acquired characteristics from the environment can be transmitted into the genetic code of offspring.

Young people, and even adults, often wonder how all the varieties and races of people could come from the same human ancestors. Well, in principle, that's no different than asking how children with different color hair ( i.e., blond, brunette, brown, red ) can come from the same parents who both have black hair.

Just as some individuals today carry genes to produce descendants with different color hair and eyes, humanity's first parents possessed genes to produce all the variety and races of men. You and I today may not carry the genes to produce every variety or race of humans, but humanity's first parents did possess such genes.

All varieties of humans carry genes for the same basic traits, but not all humans carry every possible variation of those genes. For example, one person may be carrying several variations of the gene for eye color ( i.e., brown, green, blue ) , but someone else may be carrying only one variation of the gene for eye color ( i.e., brown ). Thus, both will have different abilities to affect the eye color of their offspring.

Some parents with black hair, for example, are capable of producing children with blond hair, but their blond children (because they inherit only recessive genes) will not have the ability to produce children with black hair unless they mate with someone else who has black hair. If the blond descendants only mate with other blondes then the entire line and population will only be blond even though the original ancestor was black-haired.
