Defendant was charged in a two count information with assault with intent to murder 1 and assault with intent to rape. 2 Following a jury trial in Detroit Recorder’s Court defendant was convicted of both offenses. He was sentenced to a prison term of 20 to 30 years on the first count and 6-1/2 to 10 years on the second count. By order dated November 15, 1975, this court granted defendant’s application for delayed appeal.
Defendant raises three issues on appeal, only one of which merits discussion.
As to count 1 of the information the trial court instructed the jury that their verdict could be *591 guilty of assault with intent to murder, guilty of assault with intent to do great bodily harm less than murder, guilty of felonious assault, or not guilty. As to count 2 the jury was instructed that their verdict could be guilty of assault with intent to rape or not guilty.
The defendant requested instructions on assault and battery on count 1 and attempted rape on count 2. Both requests were refused.
The rules governing the necessity of instructing on lesser included offenses have recently been reviewed and expanded in
People v Chamblis,
"The duty of the trial judge to instruct on lesser included offenses is determined by the evidence. People v Phillips,385 Mich 30 ;187 NW2d 211 (1971). If evidence has been presented which would support a conviction of a lesser included offense, refusal to give a requested instruction is reversible error. Id, at 36. People v Hamilton,76 Mich 212 ;42 NW 1131 (1889).
"If the lesser offense is one that is necessarily included within the greater, the evidence will always support the lesser if it supports the greater.
"In the area of 'cognate’ lesser offenses, the evidence in each case adduced at the particular trial must be examined to determine whether that evidence would support a conviction of the lesser offense.” Id, at 390.
A "necessarily included” offense is one which necessarily must be committed before commission of the greater offense is possible. The greater offense must include all the legal and factual elements of the "necessarily included” lesser offense. A "cognate offense” is an offense which contains some elements not contained in the greater offense but which is related to the greater *592 offense by the fact that it shares several of the elements of the greater offense and is of the same class or category. People v Ora Jones, supra.
Assault and battery is not an offense necessarily included within the crime of assault with intent to murder.
People v Ora Jones, supra, People v Ray,
We must examine the evidence in this particular case, therefore, to determine whether that evidence would support a conviction of the lesser offense. Applying the test established in People v Chamblis, supra, we conclude that it would. If defendant had been originally charged only with assault and battery the evidence adduced at trial would have supported a guilty verdict. The requested instruction therefore should have been given. See People v Chamblis, supra, at 423.
Reversal is not required, however, for two reasons. First, the defendant was convicted of the charged offense even though instructions were given on the two lesser offenses of assault with intent to do great bodily harm less than murder and felonious assault. If the jury had doubts about defendant’s guilt of the charged offense but believed him to be guilty of some wrongdoing they could have found him guilty of one of the lesser offenses. They did not do so. We must conclude, therefore, that the jury had no reasonable doubt as to the defendant’s guilt of the charged offense. Second, on retrial the jury could not be instructed any differently than they were at the original trial because of the rule announced in Chamblis, supra, prohibiting instruction on lesser included offenses for which the maximum allowable incarceration period is one year or less in any case in which the charged offense is punishable by incarceration for more than two years.
*593 Defendant’s conviction of the offense of assault with intent to murder is therefore affirmed.
Attempted rape is an offense necessarily included within the crime of assault with intent to rape.
People v Patskan,
*594 We must conclude, therefore, that the trial court erred in refusing to instruct the jury on attempted rape. However, we must also conclude that the jury found that the crime of attempted rape had been committed since they found the defendant guilty of the greater offense of assault with intent to rape.
We, therefore, adopt the remedy employed by the Supreme Court in
People v
Jenkins,
Affirmed in part; modified in part. Remanded.

The prosecutor relies on
People v David,
It has always been recognized in this state that the duty of the trial judge to instruct on lesser included offenses is determined by the evidence. If there has been evidence adduced at trial which would support a conviction of the lesser included offense, refusal to give a requested instruction on that offense is reversible error.
People v Phillips,
It is in the area of determining when the evidence adduced at trial supports a conviction of a lesser included offense that
Chamblis, supra,
and
Ora Jones, supra,
appear to have changed the rule of law formerly followed in this state. Prior to
Chamblis
and
Ora Jones
it was generally recognized that evidence supporting a greater offense would
not
always support a lesser offense even if the lesser offense were of the genre described in
Ora Jones
as "necessarily included”. If the evidence was consistent only with a verdict of guilty of the charged offense or not guilty it was not error for the trial court to refuse to instruct even on a necessarily included lesser offense.
See People v Hearn,
"The rule is that entitlement to a charge on a lesser included *594 offense largely turns on whether, on view of the evidence favorable to the defendant, there is evidence which would justify the jury in concluding that the greater offense was not committed and a lesser included offense was committed.” (Emphasis supplied.)
This rule was expressly repudiated in Chamblis. People v Chamblis, supra, at 419-420.
Decisions of the Supreme Court which change existing rules of law are normally applied prospectively only. It should be noted, however, that although
Chamblis
and
Ora Jones
appear to have changed the rules for determining whether or not the evidence adduced at trial supports conviction of a lesser included offense the rule announced in
Ora Jones
relating to necessarily included offenses has been applied by the Supreme Court retroactively in
People v Lovett,
